Maybe you need to turn up the mic sensitivity to better pick up your voice. Or maybe the microphone device is too hot, and you need to reduce the sensitivity. 

Modern microphones make it fast and easy to capture audio on a variety of devices, including computers and laptops, professional audio interfaces, portable digital audio recorders, and even smartphones.

There are plenty of considerations that go into choosing the best mic for your specific recording needs, but its sensitivity is a factor in almost any recording situation.

Many users buy pop filters and foam covers for a better sound. Check out this article to find the difference between them.

No matter the type of recording you’re doing, your mic sensitivity can determine things like the clarity of your sound capture, your ability to apply post-processing, and more.

You also need to know how to change sensitivity using a variety of methods to get clear sound capture without unwanted background noise and without needing to apply too much gain.

We’ve put together a detailed guide that will teach you everything you need to know to easily fix mic sensitivity so you can get the perfect sound you desire.

 

What is Mic Sensitivity?

Mic sensitivity is the degree to which a capsule picks up sound.

A microphone capsule is usually comprised of internal components like a diaphragm and solid plate that measure changes in air pressure through sound waves. A sensitive device will have a diaphragm that vibrates easily, meaning it will measure smaller changes in air pressure resulting in more sensitivity.

Microphone Components

By and large, condenser mics (b) tend to be more sensitive because they employ this type of internal design. As a result, condenser models are usually used in studio recording environments to capture natural sounds and sounds that require detail.

Dynamic mics (a), on the other hand, employ components that are less conducive to movement and electricity. As such, they tend to be less sensitive and are suitable for live recording and the audio recording of louder sounds.

One important thing to note about microphone sensitivity is that there is no way to increase or decrease sensitivity after a sound has been recorded.

While there are software solutions available that can clean up or restore damaged sound files, the audio has been recorded at a certain level. You can’t fix mic sensitivity after the fact, so what you’ve recorded is what you’ve recorded.

This is why it’s a good idea to understand the difference between mic volume and mic sensitivity in order to get a recording right the first time.

 

Microphone Volume vs Sensitivity

In the world of recording, there are plenty of times where certain jargon gets used in the wrong context. For the most part, this doesn’t cause too many issues for seasoned veterans, but if you’re just starting out in recording, confusing terms with one another can lead to problems in a hurry.

Sensitivity is not Volume

An example of this can be found when talking about mic sensitivity and microphone volume or gain. These terms may get used interchangeably as they relate to how loud a sound is during the recording and playback processes, but they have very different meanings.

If you’re confused about these terms, you may not know how to adjust microphone sensitivity settings or select the right mic for your needs based on sensitivity. In doing this, you may be adding more gain and causing distortion and clipping in your sound capture.

Volume can be understood as how loud a sound is perceived based on the magnitude of the sound waves of an audio source.

In simpler terms, volume is how loud a sound is to the listener.

If you’re standing in front of a jet engine when a plane takes off, you’re going to perceive the sound as much louder than someone who hears the same sound a mile away. This is because volume is about perception, and perception of sound is usually based on proximity to a sound source and how easily the sound waves can be captured by the listener.

Sensitivity, on the other hand, is based on the point at which sound waves begin to be perceived.

You can compare sensitivity in recording gear to how your ear drums work.

When you hear a sound, you only perceive the sound and its volume because sound waves cause your ear drum to vibrate. These vibrations are translated by your brain into sound. The stronger the vibrations and the closer you are to a sound source, the more volume is perceived.

Sound Volume and Microphone Sensitivity

So, mic sensitivity is based on how easily it perceives volume.

It perceives volume by using internal components like diaphragms that measure sound waves. The diaphragm can be thought of as your ear drum.

A very sensitive device will have a thin diaphragm that reacts to sound waves easily, but a less sensitive model will require sound waves to have a greater magnitude in order to register.

This is also why you can be farther away from a sensitive microphone and still capture audio, but you need to be loud and close to a dynamic one to get the same result.

Adding more volume or gain to a mic input signal only amplifies the perceived sound. It doesn’t actually make the device itself more sensitive to picking up sound.

 

Can You Change Mic Sensitivity?

For the most part, sensitivity is based on how the microphone was manufactured.

Typically, the mic sensitivity can only be altered by changing its polar pattern.

The polar pattern determines which part of the capsule is active and at what angle. Ultimately, this can change which areas of a capsule are energized to determine where sound sensitivity will be greatest and from which direction.

Microphone Polar Patterns

While you may not have many options to fix mic sensitivity, software can be used to control the volume input of most microphones in Windows to achieve greater control over gain levels. This emulates a change to sensitivity by reducing the potential for a mic to clip and distort recordings, allowing you to record a whisper and turn up the volume to make the sound equal to a yell.

Some sound cards and audio driver enhancements may also give you options to employ noise cancellation effects in the recording path.
