Complete Guide To Microphone Frequency Response (With Mic Examples)

My New Microphone Complete Guide To Microphone Frequency Response (With Mic Examples)

Frequency response (along with polar response) is the most important specification of any given microphone. The characteristic sound of any given mic is explained largely by frequency response.

What is microphone frequency response? Microphone frequency response is the frequency-specific output sensitivity of a microphone. It details the relative output levels of the sound/audio frequencies a mic is able to reproduce. Frequency responses are specified as frequency ranges and as comprehensive graphs/charts.

In this complete guide, we'll discuss microphone frequency response in great depth. Frequency response is a critical specification to comprehend if we are to fully understand microphones. My goal here is to answer any questions you may have about microphone frequency response.

What Is Microphone Frequency Response?

As the name suggests, microphone frequency response is the microphone's response to frequencies. More specifically, frequency response is a microphone's frequency-specific sensitivity to sound frequencies.

Microphones respond to sound waves (mechanical wave energy) at their diaphragms, converting the waves into audio signals (electrical energy).

Sound waves are complex and are typically made of a range of frequencies with a range of amplitudes. These sound waves have a frequency range of 20 Hz – 20,000 Hz.

The frequency response represents the range the mic is sensitive to within the audible sound frequencies. The microphone could effectively recreate the entire audible sound range from 20 Hz to 20 kHz, or it could be limited to a smaller band within the audible frequency spectrum.

Within that pickup range, a mic's frequency response also represents the frequencies it is more sensitive to and those frequencies it is less sensitive to.

Let's look at an example to help illustrate.

In this example, we'll look at the frequency response specs for the famous Shure SM57 dynamic microphone.

Shure SM57 Dynamic Microphone


Shure is featured in My New Microphone's Top 11 Best Microphone Brands You Should Know And Use.

The specifications sheet of the Shure SM57 microphone tells us that the microphone's frequency response is 40 Hz – 15 kHz.

This means that the SM57 will effectively recreate sounds in the range of 40 Hz to 15,000 Hz. The mic will be capable of outputting these frequencies in its mic signal.

However, this is not the full story. The SM57 does not simply start recreating sound at 40 Hz and stop at 15,000 Hz. Nor does it recreate all the frequencies within this range equally.

To get the full story, we must take a look at the SM57's frequency response graph:

mnm Shure SM57 frequency response large | My New Microphone
Shure SM57 Frequency Response Graph

In the above graph, we see a frequency response line that denotes the SM57's frequency-specific sensitivity.

Although the frequency response range of the SM57 states it recreates sound down to 40 Hz, we see that, at 40 Hz, the microphone is 12 dB less sensitive than its average line (denoted by 0 dB on the Y-Axis).

Similarly, the SM57 has decreased sensitivity of about 8 dB at 15,000 Hz in the upper range.

Within the range of 40 Hz – 15 kHz, we also see a slight dip in response around 400 Hz and a large boost between 2 kHz and 12 kHz.

This is to show that the frequency response range is a sometimes misleading specification. It is better to rely on the frequency response graph to truly understand a microphone's frequency response.

Decibel And Hertz: The Measuring Blocks Of Frequency Response

Before we get too deep into our discussion of microphone frequency response, we must understand the units of frequency and relative levels.

  • Frequency is measured in Hertz or Hz (cycles per second).
  • Relative microphone output levels are measured in decibels or dB.

Frequency And Hertz (Hz)

The frequency of a sound wave or audio signal represents the number of times a sound wave repeats itself per second.

Frequency is inversely proportional to a sound wave's wavelength, and the following equation relates the two:

f = ν/λ or λ = ν/f

• f = frequency
• λ = wavelength
• ν = velocity of sound (assumed constant 343 m/s or 1,125 ft/s)

mnm Sine Wave Frequency Wavelength | My New Microphone
A Visual Representation Of The Relationship Between Frequency And Wavelength

Frequency is measured in Hertz (Hz), which means cycles/second.

In terms of pitch, doubling a sound wave's frequency results in a pitch exactly one octave above. For this reason, frequencies are best represented logarithmically rather than linearly. We see this on the X-Axis of frequency response graphs.

Relative Levels And Decibels (dB)

As discussed, frequency response is the microphone's frequency-dependent sensitivity along the range of audible frequencies.

We use the decibel (dB) to convey the differences in a microphone's output level between frequencies, we use the decibel (dB).

Decibels, like frequency, are also logarithmic and are standard units of measurement for both sound waves and audio signals.

Decibels are units that compare the intensity of sound or the power of an electrical signal to a given level on a logarithmic scale.

In the context of a frequency response graph, relative mic signal power is measured along the Y-Axis and is noted in decibels.

The frequency response graph will have a 0 dB reference point (horizontal line). The frequency response line will tell us the microphone output level at frequencies along the audible spectrum relative to this 0 dB reference point (horizontal line).

Take note of the following generalities about how we hear changes in decibels:

  • A 1 dB difference is only barely noticeable by most people.
  • A 6 dB difference is considered to be about twice (or half) the amplitude (perceived volume).
  • A 12 dB difference is considered to be about 4 times (or quarter) the amplitude (perceived volume).

For a detailed description of decibels and their role in audio and sound, check out My New Microphone's awesome reference What Are Decibels? The Ultimate dB Guide For Audio & Sound.

How To Read A Frequency Response Graph/Chart

So far, we've covered the definitions of microphone frequency response, frequency and Hertz, and relative levels and decibels. We've also seen a couple of frequency response graphs.

With that knowledge, let's dive deeper into how to read a frequency response graph or chart.

A microphone’s frequency response diagram has two axes:

  • X-Axis: frequencies (Hz)
  • Y-Axis: relative sensitivity (dB)

Let's take another look at the aforementioned Shure SM57 dynamic microphone's frequency response graph. I've explicitly added arrows to represent the X-Axis (frequencies) and Y-Axis (relative sensitivity).

| My New Microphone
Shure SM57 Frequency Response Graph With X And Y Axes Overlaid

The X-Axis

The X-axis of a frequency response graph shows the frequencies in Hertz (Hz).

Most of the time, the X-axis shows the frequencies across the audible range of sound (20 Hz – 20,000 Hz) even if the microphone does not have a response across the entire range. This is shown above in the SM57's graph.

Other times manufacturers may extend their X-axes to include frequencies in the infrasound (below 20 Hz) and ultrasound (above 20 kHz) ranges.

Let's look at some examples:

mnm Earthworks M50 with frequency response | My New Microphone
The Earthworks M50 Frequency Response
X-Axis goes from 5 Hz (infrasound) to 50 kHz (ultrasound)
mnm DPA 4006A with free field grid frequency response | My New Microphone
The DPA 4006A Frequency Response (Free Field Grid) X-axis goes up to 40 kHz


DPA is featured in My New Microphone's Top 11 Best Microphone Brands You Should Know And Use.

As mentioned, sound frequencies are heard logarithmically. In other words, we hear every doubling of a frequency as an octave above the original.

A 1 Hz difference results in a greater pitch difference in the low frequencies than in the higher frequencies.

Therefore, the X-axis is set up as a logarithmic scale.

Each octave (every doubling of frequency) takes up the same length along the X-axis. You can see this in each of the frequency response graphs mentioned in this article.

In other words, the space between one frequency value and the next frequency value gets smaller and smaller as you move from the left to the right on the graph.

The Y-Axis

The Y-axis of a frequency response graph shows the relative sensitivity in decibels (dB).

Frequency response graphs usually have their Y-axes set up in 1, 5 or 10 dB intervals. In our above examples:

  • Shure SM57 frequency response Y-axis has 5 dB intervals on grid.
  • DPA 4006A frequency response Y-axis has 5 dB intervals on grid.
  • Earthworks M50 frequency response Y-axis has 2 dB intervals on grid.

It's critical to note that the decibel values along the Y-axis are noted linearly. However, as we've discussed, decibels themselves are a logarithmic ratio.

Let's recap the generalities about how we hear level changes in decibels:

  • A 1 dB difference is slightly noticeable by most people.
  • A 6 dB difference is considered to be about twice (or half) the amplitude (perceived volume).
  • A 12 dB difference is considered to be about 4 times (or quarter) the amplitude (perceived volume).

So frequency response graphs have a set 0 dB point on their Y-axis. This provides a set 0 dB horizontal reference line across the graph.

  • Markings above the 0 dB point represent an increase in sensitivity.
  • Markings below the 0 dB point represent a decrease in sensitivity.

Remember that the Y-axis represents relative sensitivity. The absolute output of a microphone depends on many other factors, including the amplitude and frequencies of the sound waves it is subjected to.

The Frequency Response Line

So we know the measurements along to X and Y-axes. To complete the diagram, though, we need a line to actually represent a microphone's frequency response.

The frequency response line matches frequencies to the relative output level of the microphone. It gives us a solid idea of the frequency-specific sensitivity of the microphone, or, in other words, the mic's frequency response!

Let's bring back the Shure SM57's frequency response graph to look at the frequency response line. Recall that the frequency response range of the SM57 is from 40 Hz to 15,000 Hz.

This image has an empty alt attribute; its file name is mnm_Shure_SM57_frequency_response_large.jpg
Frequency Response Of The Shure SM57
  • At 40 Hz, the SM57 is not very sensitive (-12 dB).
  • From 40 Hz to just under 200 Hz, the sensitivity of the SM57 ramps up at about 6 dB per octave.
  • There is a slight dip in sensitivity around 400 Hz (2 dB).
  • There's a upward ramp in sensitivity from 2 kHz to about 6 kHz, where the mic becomes 7 dB more sensitive.
  • Past 6 kHz, the microphone has non-linear peaks and valleys in sensitivity until about 12 kHz.
  • There is a sharp high-end roll off from 12 kHz to 15 kHz (the upper end of the SM57's frequency response range).

Note that sometimes there will be multiple response lines drawn on the graph. Typically these will relate to one or more of the following:

To illustrate this, let's take a look at the frequency responses of 2 new mics:

AKG C 414 XLS Frequency Response

AKG is featured in My New Microphone's Top 11 Best Microphone Brands You Should Know And Use.

The AKG C 414 XLII has three selectable high-pass filter options (at 40 Hz, 80 Hz, and 160 Hz). The above frequency response graph shows that the 40 and 80 Hz options filter out more steeply at -12 dB/octave while the 160 Hz option filters out at a gentler -6 dB/octave.

mnm ElectroVoice RE20 with frequency response | My New Microphone
Electro-Voice RE20 Frequency Response
(Various Lines For High-Pass Filter Options & 180° Off-Axis)


Electro-Voice is featured in My New Microphone's Top 11 Best Microphone Brands You Should Know And Use.

The above RE20 frequency response graph shows us the mic's response with and without its high-pass filter engaged. It also shows us the response directly to the microphone's rear (180° off-axis).

The RE20 is a cardioid microphone, and so it has maximum rejection at 180°. The graph tells us that there's roughly 16 dB attenuation to the rear of the microphone across its entire frequency response.

Reading A Frequency Response Graph

Let's recap. When reading a microphone's frequency response graph, we will see the following:

  • The low-end roll-off of the microphone within the audible frequencies (if applicable).
  • The high-end roll of the microphone within the audible frequencies (if applicable).
  • The frequencies where the mic is most sensitive.
  • The frequencies where the mic is least sensitive.
  • How flat (or coloured) the mic's frequency response is.
  • Various lines to represent high-pass filters (if applicable).
  • Various lines to represent other EQ boosts or cuts (if applicable).
  • Various lines to represent proximity effect at various distances from the mic (some manufacturers add this to their directional mics).
  • Various lines to represent the rear pick up of directional mics (some manufacturers add this).

With a trained eye, we may look at a series of microphone frequency response diagrams and know how to maximize their potential.

However, even with a trained eye, it’s difficult to know whether or not you’ll subjectively enjoy the character and coloration in a certain situation until you actually put the microphone in that situation. After all, many other specifications affect a mic's sound.

Flat Vs. Coloured Microphone Frequency Responses

To quickly describe a microphone's frequency response, we can put a microphone into one of two groups:

  1. Flat frequency response: the microphone is equally sensitive to all the frequencies across the audible frequency spectrum. It could also mean that microphone is equally sensitive to all frequencies within its range (though there will be low-end and/or high-end roll-offs). The mic has a flat frequency response line in it graph.
  2. Coloured frequency response: the microphone is more sensitive to some frequencies and less sensitive to others. A coloured mic will often have a low-end roll-off, high-end roll-off, or both. The mic has a a non-flat frequency response line.

A perfectly flat microphone frequency response is difficult to create. “Flat microphones” will generally have some variation in their frequency-specific sensitivities.

So long as the microphone portrays a mostly horizontal frequency response line, we can call its frequency response “flat.” Of course, this is subjective.

Let's look at some examples to better understand flat and coloured frequency responses.

Flat Frequency Response Microphone Examples

Flat microphones provide consistent sensitivity across the frequency spectrum.

These are often condenser microphones (both small and large-diaphragm). The specifics of condenser capsule and diaphragm design make flat frequency response relatively easy to achieve.

Mics with flat frequency responses are chosen for their accurate and detailed recreation of sound.

Example microphones with flat frequency responses:

Neumann KM 184

The Neumann KM 184 is a small-diaphragm cardioid condenser microphone with a flat frequency response.

mnm 300x300 Neumann KM184 1 | My New Microphone
Neumann KM 184


Neumann is featured in My New Microphone's Top 11 Best Microphone Brands You Should Know And Use.

Here is the KM 184 frequency response graph:

mnm Neumann KM184 frequency response large | My New Microphone
Neumann KM 184 Frequency Response Graph

Notice that the KM 184 frequency response line is not necessarily flat, though the microphone is often considered to have a flat frequency response.

From about 100 Hz to 20,000 Hz, the response is very flat, straying only ±2 dB and only having a slight boost in the brilliance range around 8,000 Hz.

The KM 184 also has a gentle low-end roll-off starting around 200 Hz, but that doesn't overly colour the mic signal.

This shows that, although the graph is not perfect, the KM 184 is considered to have a flat frequency response.


The AKG C 414 XLII is a large-diaphragm multi-pattern microphone.

Each of its polar patterns has a slightly different but flat frequency response graph. Pictured below is the cardioid option's frequency response graph:

This image has an empty alt attribute; its file name is mnm_AKG_C414XLS_with_frequency_response.jpg
AKG C414 XLII “Flat” Frequency Response Graph

Like the aforementioned Neumann KM 184, the AKG C 414 XLII is not perfectly flat. However, it is certainly arguable that the C 414 has a flatter frequency response than the KM 184.

With no high-pass filters engaged, we see only the slightest low-end roll-off. This is followed by an almost perfectly flat response until about 1,000 Hz.

Above 1 kHz, there are slight variations (no more than ±3 dB) in sensitivity.

The AKG C 414 XLII is an excellent example of a flat microphone.

DPA 4006A

The DPA 4006A is a small-diaphragm cardioid microphone that has an extremely flat frequency response.

This image has an empty alt attribute; its file name is mnm_DPA_4006A_with_free_field_grid_frequency_response-1024x236.jpg
DPA 4006A “Flat” Frequency Response Graph

Note that the DPA 4006A frequency response graph goes up to 40 kHz on the X-axis (rather than the typical 20 kHz).

From 20 Hz to about 5,000 Hz, the frequency response of the 4006A is completely flat.

The upper-frequency response depends on if the sound source is on-axis (where the microphone is pointing) or diffuse (off-axis or reflecting around the acoustic space).

On-axis sounds are subjected to a gentle boost in the upper-frequency range, while diffuse sounds are gently rolled off.

Flat/Coloured Frequency Response Microphone Examples

Some microphones fall into the middle ground between “flat” and “coloured.”

Ribbon microphones often fall into this grey area. They sound very accurate and natural, even though they do not typically portray overly flat frequency responses.

These microphones yield a fairly natural sound but will have some jaggedness in their frequency response line. Often these “flat/coloured” mics have significant high-end and/or low-end roll-offs.

Mics with flat/coloured frequency responses are often chosen for their character while accurately and naturally capturing sound.

Example microphones with flat/coloured frequency responses:

Electro-Voice RE20

The Electro-Voice RE20 is a moving-coil cardioid dynamic microphone with a relatively flat frequency response (compared to other moving-coil dynamic mics).

This image has an empty alt attribute; its file name is mnm_ElectroVoice_RE20_with_frequency_response-1024x491.jpg
Electro-Voice RE20 “Flat/Coloured” Frequency Response Graph

The frequency response line of the Electro-Voice RE20 is far from a flat line. However, from about 70 Hz to 14 kHz, there is really only a ±2 dB variation in the mic's response.

The low-end and high-end roll-offs certainly play into the colouration of the RE20, along with the jaggedness of the response line.

So the Electro-Voice could be considered both flat and coloured. It is certainly flat relative to many other moving-coil dynamics but is definitely coloured if compared to the above condenser microphones.


The AEA R84 is a bidirectional ribbon microphone with a frequency response typical of high-end ribbon mics.

mnm AEA R84 with frequency response graph | My New Microphone
AEA R84 “Flat/Coloured” Frequency Response Graph


AEA is featured in My New Microphone's Top 11 Best Microphone Brands You Should Know And Use.

Ribbon microphones are cherished for their natural sound, especially when recording digital audio.

The gentle high-end roll-offs of ribbon mics (like the AEA R84) cause them to approximate how we naturally hear sound.

The frequency response line of the AEA R84 is far from flat, but the microphone sounds incredibly natural and picks up sound accurately.

I would not call the R84's frequency response flat. However, the definitions of flat and coloured mics may very well fit in the grey area.

Coloured Frequency Response

Coloured microphone exhibits peaks and valleys within their frequency responses.

Due to their rugged and heavy nature, many moving-coil dynamic microphones have coloured frequency responses brought on by resonant frequencies and inertia within their diaphragms and capsules/cartridges.

Coloured microphones are often chosen to accentuate the important frequencies of their intended sound sources while suppressing the not-so-important or competitive frequencies.

Example microphones with coloured frequency responses:

Shure Beta 52A

The Shure Beta 52A is a moving-coil dynamic microphone with a supercardioid polar pattern and extremely coloured frequency response.

mnm 300 Shure Beta52A | My New Microphone
Shure Beta 52A

Here is the Shure Beta 52A frequency response graph:

mnm Shure Beta52A frequency response large | My New Microphone
Shure Beta 52A Frequency Response Graph

The peaks and valleys in the Beta 52A are vast.

The microphone heavily accentuates 4 kHz and is very sensitive to low-end frequencies (particularly at close distances due to the proximity effect). There is also a very sharp high-end roll-off between the peak at 4 kHz and the upper point of the 52A's frequency response at 10 kHz.

The extreme colouration of the Beta 52A makes it a specialty microphone marketed as a kick drum mic.

In fact, the Shure Beta 52A is my top recommendation in my Best Kick Drum Microphones article.

Shure SM57

The Shure SM57 is a moving-coil dynamic microphone with a cardioid polar pattern and coloured frequency response.

mnm Shure SM57 with frequency response graph | My New Microphone
Shure SM57 “Coloured” Frequency Response Graph

As we can see, the SM57 is definitely coloured.

The coloured frequency response of the SM57 makes it an excellent choice for vocals and other instruments, particularly in live situations.

  • The low-end roll-off improves noise cancellation and gain-before-feedback.
  • The peak at 6 kHz improves speech intelligibility and accentuates many instruments.
  • The high-end roll-off reduces harshness while improving gain-before-feedback.

The Frequency Response Microphone Specification

Frequency response is a critical specification for microphone manufacturers to put on their mic spec sheets.

For more information on microphone specifications and the most important mic specs, check out my articles Top 5 Microphone Specifications You Need To Understand and Full List Of Microphone Specifications (How To Read A Spec Sheet).

As we've discussed, there are two general ways of expressing microphone frequency response:

  1. The range of frequencies a microphone will reasonably reproduce. This will often be expressed with a measure of tolerance.
  2. A graph showing the relative sensitivity of a microphone to frequencies within its “range.”

The range of frequency response is not overly helpful (even with a measure of tolerance).

For example, a 20 Hz – 20,000 Hz frequency response range tells us a mic will effectively output frequencies across the audible range, but we have no idea if the mic will boost or cut any particular frequencies within this range.

20 Hz – 20,000 Hz ±3 dB tells us that the mic frequency response is at least fairly consistent and flat. However, we're still guessing at the frequencies where the mic is 3 dB more sensitive and where it is 3 dB less sensitive.

By far, the best way to convey microphone frequency response is with a graph.

Frequency Response Specification Example: Shure Beta 52A

The Shure Beta 52A has a frequency response specification of 20 Hz – 10,000 Hz. Shure also provides the following frequency response graph.

mnm Shure Beta 52A with frequency response graph | My New Microphone
Shure Beta 52A Frequency Response Graph

As you can see, the graph yields so much information that “20 Hz – 10,000 Hz” cannot convey.

Choosing The Microphone With The Proper Frequency Response

There are many different microphones on the market with many different frequency responses.

We've discussed flat and coloured frequency responses and how a microphone's frequency response makes up the mic's characteristic sound.

So how do we choose the right microphone with the right frequency response for the right purpose?

There are a few things to ask ourselves.

  • What sound source(s) are we miking?
  • In what acoustic situation are we miking the sound source(s)?
  • How are we miking the sound source(s)?

In other words, we should ideally understand the sound and frequency profile of the source and the acoustics of the space. We should then optimally choose a mic with a frequency that enhances the sound of the source, taking into consideration the technique(s) we'll be using to place the microphone in order to capture the source.

Let's look at some examples:

Choosing A Mic Frequency Response For Voiceover

Voiceovers are ideally recorded solo in soundproof isolation booths. These acoustic spaces have as little room sound and reflections as possible.

This allows us to position the microphone optimally for the room and the voiceover performer.

So we have an ideal recording environment, and we're recording the human voice. In this situation, a microphone with a flat frequency response would be ideal.

A flat frequency response will pick up the voiceover with as little colouration as possible.

A popular voiceover microphone example found in professional studios around the world is the famous Neumann U87 Ai:

| My New Microphone
Neumann U 87 Ai

The Neumann U 87 AI has 3 selectable polar patterns and a high-pass filter.

Here are the frequency response graphs for each of the polar patterns (omnidirectional, cardioid, and bidirectional):

mnm Neumann U87AI frequency responses condensed | My New Microphone
Frequency Response Graphs Of The Neumann U 87 AI

Although any of the above polar patterns would work well on voiceovers in isolation booths, the cardioid pattern is the most popular.

As we see in the graph above, the U 87 cardioid mode is wonderfully flat between about 70 Hz and 5,500 Hz. This is what we want in a voiceover microphone.

The slight low-end roll-off helps to eliminate noise in the signal.

If we really need extra low-end, the cardioid mode does exhibit proximity effect, so we can easily move the performer and mic closer together. Conversely, if there's too much low-end or the proximity effect is too much, there is a high-pass filter.

The 2-3 dB bump in sensitivity between 6 kHz and 12 kHz adds a bit of sparkle to a voiceover.

The slight high-end roll-off helps to reduce the harshness or brightness of the voiceover. This is particularly helpful in digital audio, which is sometimes too clean/bright.

Choosing A Mic Frequency Response For Live Vocals

In most situations, live vocals are performed on relatively noisy stages. Even in small ensembles and venues, there will likely be other instrumentation, crowd noise, room noise, and the PA system that will also be entering the mic designated for the vocals.

For this reason, live vocal mics are positioned as close as possible to the vocalists. This makes for the best isolation of the vocal performance possible.

Typically, they also have cardioid polar patterns and point away from loudspeakers. This is to increase gain-before-feedback and yield a cleaner, clearer vocal signal.

The above two points tell us that the typical live vocal mic will exhibit proximity effect.

Because the stage will likely be noisy and there will be a significant bass boost due to the proximity effect, a microphone with a low-end roll-off in its response is preferred for live vocals.

A high-end roll-off is also nice to have in order to filter out any harshness in the signal due to cymbals and high-frequency sound sources.

These roll-offs also help to reduce the likelihood of microphone feedback.

Additionally, because the environment will probably be noisy, a boost in the speech intelligibility range (roughly 2 kHz – 6 kHz) will allow the vocals to cut through the mix a bit more without the need for equalization after the fact.

The most popular live vocal microphone in the world is the Shure SM58 (link to check the price on Amazon):

| My New Microphone
Shure SM58

The Shure SM58 is a moving-coil dynamic microphone with a cardioid polar pattern.

Here is the frequency response of the Shure SM58:

mnm Shure SM58 frequency response | My New Microphone
Shure SM58 Frequency Response Graph

The Shure SM58 has a frequency response that lends itself extremely well to live vocals.

The low-end roll-off effectively filters out low-end rumble for electrical mains and stage vibration.

However, because the mic is directional, the proximity effect will effectively flatten out the lower frequency response, assuming the vocalist will be very close to the mic.

From about 100 Hz to 2,000 Hz, the SM58's frequency response is flat. This allows it to capture the bulk of the vocals very accurately.

The boost in the presence range (3 kHz – 10 kHz) allows the intelligibility of vocal performance to cut through the mix.

The high-end roll-off filters out any excessive brilliance from the voice or environment.

Choosing A Mic Frequency Response For A Snare Drum In A Drum Kit

Miking a drum kit can be as simple as placing an overhead or room mic, or it can be as involved as close-miking every single drum. In most situations (when equipment allows), drum kits are miked with two overhead mics, a dedicated kick drum mic, and a dedicated snare drum mic.

Snare drums typically have a strong fundamental frequency in the low-mid range (100 Hz – 250 Hz). Above the fundamental, there's really no rhyme or reason to the frequencies. However, snare drums usually have another peak in the upper mid-range between 3-6 kHz.

Selecting a mic with a frequency response that boosts around the fundamental and upper mid-range peak of the snare drum will help accentuate the character of the snare.

The acoustic environment of a snare drum (or any other drum within a drum kit) is noisy, to say the least. Isolating the snare is impossible, but we still strive to do so.

In attempting to isolate the snare, we generally mic it very closely with a directional microphone. This means that the proximity effect will be a factor to account for.

Choosing a mic with a low-end roll-off in its frequency response will help filter out low-end rumble, the sound of the kick drum, and combat the proximity effect.

A high-end roll-off is also preferable to effectively filter out the brilliance of the drum kit's cymbals.

A go-to for miking snare drums has already been mentioned several times in this article. It is the famous Shure SM57:

mnm 300x300 Shure SM57 1 | My New Microphone
Shure SM57

The Shure SM57 is a moving-coil dynamic microphone with a cardioid polar pattern.

Here is the frequency response graph of the Shure SM57:

mnm Shure SM57 frequency response large | My New Microphone
Shure SM57 Frequency Response Graph

The above graph shows that the SM57 has a frequency response that suits the typical snare drum quite nicely.

Its low-end roll-off helps filter out the other drums in the kit. However, the proximity effect will still allow the mic to pick up the low-end of the snare, assuming we are close-miking the snare.

The upper-midrange boost helps to accentuate the snap and character of the snare drum.

The high-end roll-off of the SM57 helps filter out the sound of the drum kit's cymbals.

Choosing A Mic Frequency Response For A Grand Piano

The grand piano is a huge instrument with a huge range.

Multiple microphones positioned at different spots around the instrument and acoustic space are often used to capture the best sound of a grand piano.

Flat, extended frequency responses are ideal for capturing the truest sound of the beautiful grand piano.

A common environment to mic up a grand piano would be in a concert hall. The audience noise is typically negligible in these large reverberant rooms, but the mics will pick up sound reflections around the acoustic space. This is perfectly fine and generally wanted.

Omnidirectional mics with flat frequency responses, in general, sound the most natural. And so, grand pianos are typically recorded with these mics!

A recommended mic for capturing the sounds of a grand piano if the AKG C 414 XLS:

The AKG C 414 XLS is a large-diaphragm multi-pattern condenser microphone.

Although the AKG C 414 XLS has 9 selectable polar patterns, we'll focus on the omnidirectional pattern.

Here is the frequency response of the C 414 in omni mode:

The flat nature of the AKG C 414 XLS frequency response allows it to capture the true sound of the grand piano and the reverberations of the acoustic space.

If there is too much low-end rumble in the mic signal, try engaging one of the 3 selectable high-pass filters.

To read more about choosing a microphone for the grand piano, check out my article Best Microphones For Grand Piano.

Choosing a microphone with a complimentary frequency response comes with the practice of recording various instruments. To recap, a solid strategy includes just 3 steps:

  1. Understand the frequency range (fundamentals and harmonics) of an instrument.
  2. Choose a microphone with a frequency response that enhances the important frequencies of that instrument.
  3. Be aware of mic placement; the nearby extraneous noise; and the proximity effect.

How Do Microphones Pick Up Different Frequencies?

Different sound frequencies vibrate the air at different rates. As we've discussed, frequency is measured in Hertz (Hz), which is cycles or vibrations per second.

Sound vibrations in the air are caused by longitudinal waves (sound waves). These waves have peaks (max compression) and troughs (max rarefaction), just like other waves.

mnm Sine Wave Amplitude Cycle Peak Trough | My New Microphone

The wavelength of these longitudinal waves is inversely proportional to the frequency (assuming a constant speed of sound).

mnm Sine Wave Frequency Wavelength | My New Microphone

Lower frequencies naturally have a greater amplitude (a fundamental frequency of an instrument, for example, has a greater amplitude than its harmonics).

These “quieter” harmonics are added to the overall vibration of the air, resulting in all sorts of interesting waveforms. So we have slower-moving waves (low frequencies) and faster-moving waves (higher frequencies) effectively summed together to vibrate the air in complicated ways.

Our ears pick up on this and send an electrical signal to our brains.

Microphone diaphragms are very similar!

A microphone’s diaphragm will vibrate according to the sound waves it is exposed to.

Microphone diaphragms, capsules/cartridges, and overall bodies have natural resonant frequencies that affect the peaks and valleys within their overall frequency response. This is particularly relevant in the relatively heavy diaphragms of moving-coil dynamic mics.

The Determining Factors Of Microphone Frequency Response

Frequency response is the most significant determinant of a microphone’s characteristic sound. It is a function of many variables both inside and outside the microphone itself.

The following factors influence the frequency response of a microphone:

The Weight Of The Diaphragm

The weight of the microphone diaphragm is a limiting factor in the high-frequency response.

The inertia of a heavy diaphragm makes it less sensitive to smaller wavelengths of sound (higher frequencies). For this reason, the relatively heavy moving-coil diaphragms have poorer high-frequency sensitivity than their lighter condenser and ribbon counterparts.

The Size Of The Diaphragm

The diameter of a circular diaphragm plays a big role in determining its microphone’s high-frequency response.

If a sound wave has a wavelength equal to the diameter of a diaphragm, it will apply equal amounts of both positive and negative pressure, effectively cancelling itself out.

Sound waves shorter than this wavelength get quite “phasey,” especially when both sides of the diaphragm are exposed to external sound pressure. This further reduces the clarity of the high-frequency response.

The shorter the wavelength, the higher the frequency and so smaller diaphragms can physically reproduce higher frequencies than large diaphragms.

The Shape Of The Diaphragm

The shape of the diaphragm is one factor in the resonant frequencies of the microphone.

Typical moving-coil and condenser diaphragms are circular and susceptible to resonant frequencies (think standing waves).

A wavelength having exactly twice the length of the diaphragm diameter causes a sort of standing wave on the diaphragm. The nature of the diaphragm shape slightly accentuates this wavelength’s frequency. Integer multiples of the wavelength behave interestingly on the diaphragm, causing either self-cancellation or resonant standing waves.

Ribbon microphones are different. Their long, corrugated ribbon diaphragms typically do not have strong resonant frequencies due to their irregular shape!

Moving-coil diaphragms often have leaf slots and indents where the coil attaches. This irregular shape also affects the microphone’s frequency response.

The Tension Of The Diaphragm

The tension of a diaphragm affects the inertia of the diaphragm and the frequency response of the microphone.

Think of tuning a snare drum. The tighter we stretch the skin, the higher the resonant frequency of the snare drum—similarly, the tighter a microphone diaphragm, the higher its resonance frequency due to tension. Just don’t hit microphone diaphragms with drumsticks!

In small-diaphragm condenser microphones, this tension may cause resonance way above the audible range of human hearing.

Large-diaphragm condensers will usually have a high-frequency boost due to diaphragm tension.

Ribbon diaphragms are often loose enough for their resonant frequency (due to tension) to be in the sub-bass region or even below the audible range of human hearing.

The Damping Material And Space Around The Capsule

Microphones typically have protective grilles around their capsules. Within the grille and around the capsule, there is often dampening acoustic foam. There is a space between the grille, foam, and capsule.

The damping material helps protect the capsule from plosives while damping higher frequencies.

The space within the mic has the potential to promote short-standing waves.

Although minor and terribly complicated, these seemingly small factors are serious parts of microphone design and frequency response.

Generally speaking, diaphragms are damped at −6 dB per octave to produce a natural-sounding frequency response.

Directionality Of The Capsule

Yes, even the directionality of a microphone affects its frequency response. This is particularly true when moving off-axis from directional microphones.

In a directional microphone, the capsule is designed with a specific “path” that sound must travel to get from the front of the diaphragm to the back of the diaphragm. This distance affects the high-frequency roll-off of microphones.

The frequency roll-off starts at a peak point: At a frequency with a wavelength twice that of the path length from front to the back of the diaphragm. At this frequency, there is a maximal pressure difference between the two sides of the diaphragm, causing a peak in frequency response.

The pressure difference above this cut-off frequency will get smaller and smaller. The amplitude difference will also get smaller with higher frequencies. These both cause a decrease in frequency response.

Note that microphones are more directional at high frequencies and become increasingly omnidirectional at low frequencies. 

Therefore, the off-axis frequency response of a directional microphone will have relatively less highs and more lows compared to the on-axis response. As we move the sound source further off-axis, the microphone becomes worse at reproducing high frequencies.

Resonant Frequencies Of The Microphone Body

All physical objects have resonant frequencies (think tuning forks). Microphones are no different.

Quality microphone bodies are designed with this in mind, and special care is taken to minimize the presence of resonant frequencies. But the fact remains that these resonant frequencies of the microphone body will affect the frequency response.

Distance Between The Sound Source And The Microphone

Though not a part of the microphone anatomy, sound source distance plays a role in the frequency response of directional microphones, specifically on the low-end. This is due to the proximity effect, which we’ll discuss in more detail later.

The closer the sound source is to a microphone, the more low frequencies the microphone will reproduce.

Output Impedance Versus Load Impedance

Voltage transfer between microphone and preamp increases as the load impedance increases compared to the mic output impedance. A load impedance at least 5 times that of the output impedance is preferable.

However, a microphone’s output impedance is frequency-specific and is often much greater at low frequencies. Therefore, low load impedances may cause a loss of low-frequency response.

High frequencies can be lost at the impedance converters (step-up transformers or circuitry) due to the increase in the mic signal impedance.

The Frequency Response Of The Human Ear

Yes, our ears also have a frequency response!

The outer limits of human hearing, as we’ve discussed, are 20 Hz on the low end and 20,000 Hz on the high end.

We’ve evolved to have a sensitivity between 2,000 Hz and 5,000 Hz. This is the range of speech intelligibility in the human voice. As we discussed earlier, vocal microphones benefit from a boost in this range.

As we get lower on the spectrum, heading toward 20 Hz, we become less and less sensitive to SPL levels.

We actually feel these sub-bass frequencies (20 Hz – 60 Hz) more than we hear them.

On the higher end of the spectrum, we slowly lose sensitivity as we get older and repeatedly damage our hearing.

For example, from spending so much time playing music in loud bands and attending loud shows, I personally have a hard time hearing anything above 16,500 Hz… Protect your ears!

To better understand the complicated frequency response of human hearing, check out the Fletcher-Munson curves:

mnm Fletcher Munson Curves 1 | My New Microphone
Fletcher-Munson Curves

The above curves show us, generally speaking, the relative frequency-specific sensitivities of human hearing.

On the above graph, you'll find several lines related to different phon values.

A phon is a level of perceived loudness. You'll see that the lower the “phon” line, the less sound pressure level is needed for us to hear a frequency.

  • 0 phon is the threshold of hearing
  • 120 phon is the threshold of pain

At the low-end (20 Hz), we see that it would take a great sound pressure level for us to actually hear a sound. However, at a frequency of 4 kHz, we are very sensitive to sound pressure variations.

What Are Frequency Bands?

Before we move on, I’d like to give a bit more information on the frequency bands (ranges) and how we hear them:

Note that these ranges are simply rough guidelines. There is no standard here.

The frequency ranges are:

  • ≤ 60 Hz = Sub Bass.
  • 60 Hz – 250 Hz = Bass.
  • 250 Hz – 500 Hz = Low Mids.
  • 500 Hz – 2 kHz = Midrange.
  • 2 kHz – 4 kHz = High Mids.
  • 4 kHz – 6 kHz = Presence.
  • ≥ 6 kHz = Brilliance.

≤ 60 Hz = Sub Bass

This frequency band is felt more than it’s heard (check out the Fletcher-Munson curves). Most instruments and sounds lack information in this range.

Pay special attention to the sub-bass frequency response in the microphones for kick drums, bass guitar amplifiers, and tubas.

60 Hz – 250 Hz = Bass

This is where most of the “musical” bass information is. The fundamental frequencies of many instruments are in this range, including the fundamental frequency of most human voices!

250 Hz – 500 Hz = Low Mids

This range contains the stronger harmonics of the bass instruments and the fundamentals of some higher-pitched instruments. Too much response in this band may cause the microphone to sound “muddy.” Not enough response in this band may cause the mic to sound too thin.

500 Hz – 2 kHz = Midrange

The human ear starts getting more sensitive in this range. This range contains weaker harmonics from bass instruments and stronger harmonics from higher-pitched instruments.

2 kHz – 4 kHz = High Mids

The human ear is the most sensitive in this range. A microphone that has a substantial boost or cut in this band will not accurately recreate a sound's timbre.

4 kHz – 6 kHz = Presence

If a microphone is sensitive in this range, it may add more presence to the sound, or it may sound harsh. There’s a fine line.

If there’s a dip in a microphone’s frequency response in this band, it can make the source sound transparent or further away than it actually is.

≥ 6 kHz = Brilliance

Many dynamic microphones drop off somewhere in the “brilliance” frequency band (even though they may be rated to capture up to 20 kHz).

This band is part of why condenser microphones, in general, sound more “hi-fi” than their dynamic counterparts. Condenser microphones typically do a great job at picking up frequencies in this range, which encompasses all the upper harmonics of sounds as well as the “air” and “sparkle” of a sound (those are my technical terms).

Ribbon microphones tend to gently roll off in the brilliance band, therefore reproducing a “warm” sound.

How Is Frequency Response Measured In Microphones?

The process of properly calculating a microphone’s frequency response is simple to conceptualize. However, microphone manufacturers need expensive equipment to actually measure correctly. This equipment includes:

  • An anechoic chamber
  • A perfectly calibrated loudspeaker

An anechoic chamber is absolutely acoustically dead. There is no ambient noise in an anechoic chamber, nor are there any reflective surfaces in the room itself. It’s not uncommon to have negative dBA values when measuring the room noise of an anechoic chamber. This is incredible!

Next, a perfectly calibrated loudspeaker is needed. This loudspeaker needs a flat frequency response and must be able to output 20 Hz to 20,000 Hz evenly. Like the anechoic chamber, a truly incredible amount of design detail must go into this loudspeaker.

The microphone in question is placed in front of the loudspeaker, connected via XLR to a calibrated spectrum analyzer, and the test is ready to take place.

Pink noise is played through this loudspeaker and captured by the microphone.

Pink noise is used because it has equal energy across all octaves in the human range of hearing. And so, if the resulting frequency response diagram is not flat, it has something to do with the microphone’s response to particular frequencies.

The microphone signal is routed into a spectrum analyzer, and a frequency response chart is then produced.

This sounds expensive, and it is!

An Alternative Way To Measure Frequency Response In Microphones

Instead of using this expensive equipment to produce an accurate frequency response, manufacturers (and audio enthusiasts alike) compare against a known reference.

By analyzing the microphone in question against another mic with a known frequency response, we calculate the differences and deduce a frequency response for the unknown microphone!

In this option, we need to ensure that everything but the microphones is the same in both tests:

  • The room
  • Everything in the room
  • The position of the microphones
  • Distance to the speaker
  • The same pink noise is to be used and at the same volume

This is a cheaper option. The room doesn’t need to be anechoic since both microphones will be subjected to the same stimulus. Though acoustically dead rooms are better since reflections of sound within the room will give a skewed result.

Also, the loudspeaker doesn’t need to be perfect but should be calibrated so we know the pink noise is as flat as it can be.

We find the differences in frequency response between the two microphones using frequency analyzers. From that, we chart out a new frequency response diagram based on the known diagram.

Even that sounds tedious…

And it is, but it’s worth having in a datasheet to better serve the customer.

However, some manufacturers do more “guesswork” than others regarding their frequency response charts. So sometimes, the frequency response diagram isn’t necessarily accurate.

Another way these charts lack accuracy is in the scale of the graph. Oftentimes the response line is smooth and sums the average sensitivity (rather than being very precise and jagged). This is fine to purvey a general sense of where the mic naturally boosts and cuts in the frequency spectrum but lacks the true detail of the real frequency response.

So basically, there are 3 ways of measuring a microphone’s frequency response:

  1. An anechoic chamber with a calibrated loudspeaker
  2. Comparison to a known microphone
  3. Guesswork

Wow, the precision really dropped off quickly!

The Proximity Effect On Frequency Response

The proximity effect is a microphone phenomenon in which moving a mic closer to a sound source actually boosts its sensitivity to low-end frequencies.

Therefore, a microphone’s frequency response changes depending on its proximity to the source it is capturing.

Here is a graphical representation of the proximity effect in the Shure Beta 57A microphone:

mnm Shure Beta 57A with frequency response graph | My New Microphone
Shure Beta 57A Frequency Response Graph With Proximity Effect Variations

How can this be?

First, there are two kinds of microphone principles: the pressure principle and the pressure-gradient principle. 

The proximity effect only affects pressure-gradient microphones. Pressure-gradient microphones are directional (cardioid and figure-8 polar patterns and all the variations thereof).

The pressure difference between the back and front of the diaphragm causes the signal, and the difference is physically greater in high frequencies than in low frequencies (due to phase differences in shorter wavelengths). Microphones dampen the diaphragm to help balance out the signal and capture a “flatter” frequency response.

This works great at a fair distance.

However, when the sound source gets close to the capsule, things change. Let’s say there’s a distance D between the front and back of a mic’s diaphragm, and the sound source is a distance D from the front of the diaphragm.

This means the source is 2D from the back, and therefore the SPL is four times louder at the front than it is at the back.

At these distances, the difference in pressure between the front and the back is barely dependant on the frequency and much more dependent on amplitude.

And so, the dampening actually boosts the bass frequencies rather than equalizing them. This boost results in a variation of the frequency response in the low end of a microphone and are known as the proximity effect!

Methods To Change A Microphone's Frequency Response

How do I change a microphone’s frequency response? Although an innate characteristic of a microphone, the frequency response can be altered by the following:

Proximity Effect

As we've touched on earlier, the proximity effect states that as a directional microphone moves closer to a sound source, the mic's bass response is increased.

Moving The Sound Source Off-Axis

Microphones naturally become more omnidirectional at lower frequencies and more directional at higher frequencies. Therefore, moving a sound source off-axis will effectively reduce the high-frequency response of the mic.

Cupping The Microphone

By cupping the microphone, we introduce more standing waves around the microphone diaphragm. This causes alterations to the mic frequency response.

Introducing Or Removing Grilles And Acoustic Foam

Any time we add or take away material from around a microphone diaphragm, we risk altering the way sound affects the diaphragm. In doing so, we alter the frequency response.

Supplying Varying Amounts Of Phantom Power

Some active microphones that require phantom power are capable of running on a range of DC voltages and not only the standard +48 volts.

However, many of these mics will have limited functionality with less voltage. One of the ways this decreased functionality shows itself is in a decreased high-frequency response.

Changing The Load Impedance

Varying the load impedance of a microphone will affect the signal flow.

There are variable impedance preamps on the market that can be used to alter the microphone's sound. These preamps are best known and paired with ribbon microphones.

Engaging Filters

Engaging high-pass filters and frequency boosts (presence boosts, etc.) will directly affect a microphone's frequency response.

What is microphone sensitivity? Microphone sensitivity is defined as the output signal strength of a mic (mV or dBV) relative to the sound pressure level the mic is experiencing (measured with a 94 dB SPL or 1 Pascal 1 kHz tone). The sensitivity rating has to do with the signal output rather than the reactivity to sound.
