How To Lower Microphone Sensitivity


The microphone is a basic hardware component in any smart device. Without the mic, you won’t be able to call or give any voice input to your device. However, your device’s microphone can sometimes malfunction, making your voice sound really bad. It is due to your mic’s sensitivity settings which need to be lowered. 

Quick Answer

You can lower the mic sensitivity on any Android smartphone, iPhone, Mac, or Windows computer. For Androids, you need to install a separate application offering mic sensitivity customizations. However, iPhones, Macs, and Windows PCs have built-in options to lower their mic sensitivity.

Adjusting your gadget’s microphone sensitivity ensures that the sound you’re recording doesn’t come out too loud or too muffled. The article below will cover all the details you need to lower the mic sensitivity on your smartphone or computer. So, let’s get started.

Lowering Mic Sensitivity on Android

Most Android phones do not come with an in-built microphone customization option. You will need to download a third-party application like Microphone Amplifier to lower your mic sensitivity.

  1. Search and install Microphone Amplifier.
  2. Launch the application and give storage permissions to access the main menu.
  3. Click “Enter Amplifier”, and you will see different sliders on the screen. Sliding the “Audio Gain” slider to the right will increase mic sensitivity and vice versa.
  4. You can also move the “Input Filter” slider to the right, improving noise suppression.

After applying these settings, you can record test audio and listen to it to see how well the effects have been implemented. You can listen and adjust several times until you reach the desired outcome.

Lowering Mic Sensitivity on iPhone

For iPhones, the mic sensitivity is linked to the actual volume of your iPhone, so you can raise or lower the sensitivity by adjusting your volume rockers. Another thing you can do is turn on the noise cancellation feature, as it will filter out unwanted background noises.

  1. Launch the Settings menu on your iPhone.
  2. Scroll down and tap on “Accessibility”.
  3. Under the “Hearing” menu, select the “Audio/Visual” option. 
  4. You will see a “Phone noise cancellation” toggle. Turn the toggle on to enable noise cancellation on your iPhone.

If your iPhone is connected to AirPods, then you need to adjust their own mic settings as they come with an in-built microphone.

  1. Open the Settings panel on your iPhone.
  2. Scroll down and tap on “Bluetooth”.
  3. Under “My Devices”, tap on the little info icon next to your AirPod’s name.
  4. You will see the “Press and Hold AirPods” menu. Ensure that your AirPods are set to “Noise Control” mode.

You can also set the microphone to always record from the left or the right side. After this, your iPhone will only use the selected AirPod to record sound.

Lowering Mic Sensitivity on Mac

You can easily adjust the microphone sensitivity on a Mac by diving into its settings. Follow the steps mentioned below.

  1. Launch the Settings panel on your Mac.
  2. Search and select System Preferences.
  3. Click on the “Sound” option.
  4. Click on “Input” to reveal a slider. You can adjust the slider according to the microphone sensitivity you require.

Lowering Mic Sensitivity on Windows

In Windows PC, microphone sensitivity controls are also tucked in the settings panel.

  1. Head to the “System Settings” on your Windows PC.
  2. Navigate and click on “Sound”.
  3. Under the “Input” tab, you will see a menu with all microphones connected to your PC. Select the one whose sensitivity you want to adjust.
  4. Click on the “Device Properties” option below your microphone name.
  5. You will see a “Volume” slider. Bringing the slider to the left will lower its sensitivity.

You can also record test audio on your PC and adjust it until you hear a clear-cut recording.

The Bottom Line

Lowering mic sensitivity is the best option when your device’s microphone picks up a lot of background noise in the recordings. You can adjust the mic settings on any device, like smartphones or computers. For Androids, you need to install a third-party application, while iPhones, Macs, and Windows PCs have mic adjustments built into their settings.

This article has covered all the steps you will need to lower your mic sensitivity. We hope that you have found the answers to all your queries in this article.

Frequently Asked Questions

What is the difference between noise cancellation and mic sensitivity?

Mic sensitivity is the ability of your mic to respond to faint or loud sounds. A highly sensitive mic can even record the faintest sounds. On the other hand, noise cancellation is the ability of your mic to remove the distant background noise from your recording.

Is lower mic sensitivity always better?

Lower mic sensitivity is usually better as it will not pick up your breathing sounds and other unwanted noise. However, you might need high sensitivity to record very soft sounds.
