How to Reduce Mic Noise

By Jonathan Croswell

Microphone noise can be a frustrating complication of recording or transferring sound. Mics are touchy, influenced by a number of variables ranging from jack connections to electromagnetism. One of the purposes of sound checks prior to events and concerts is to ensure the microphones are working properly and have been adjusted to create the highest-quality sound. Here are some steps you can take to optimize your mic's performance and reduce unwanted noise.

Step 1

Check the jack connection your mic is plugged into. It could be loose, or there might be a better plug to use. Try different plug-ins to see where you get the best sound.

Step 2

Make sure no other mics or interfering devices are near the mic you are testing. These can cause high-pitched noise that will come through the speakers.

Step 3

Check for wind or any moving air that might be hitting the mic, and minimize it.

Step 4

If your mic is plugged into your PC, go into Control Panel, then Audio and Sound Devices, and then select Test Hardware. This will allow you to calibrate the recording volume of your microphone.

Step 5

Search the Internet for any software that might reduce hissing sounds or other noises created by your microphone.

Tips & Warnings

  • If you are using a microphone attached to a webcam or one not created specifically for audio recording, consider upgrading. No amount of doctoring will improve the audio quality of these basic microphones.Purchase a mic cover if you do not currently have one. These soften some of the sharper sounds that create excessive noise through microphones.
