Microphones

How to Stop Mic from Picking Up Background NoiseMic picking up too much background noise is quite apparent as various factors are affecting the microphones. Each speaker, performer, room, and surroundings are different. Before you start reading about how to make your mic not pick up background noise, first, you should understand something about the audio sound.

There are three types of unwanted sounds when it comes to mics.

  • Broadband Noise – it is distributed over a wide range of frequencies. It’s a continuous noise.
  • Narrow Band Noise – it is limited to smaller areas and caused by bad grounding and poorly attached cables.
  • Impulse Noise – it has a very high frequency, but it lasts only for a short period of time. It includes sharp sounds such as pops.

If you are on microphones, then you should keep these things in mind before going to change any settings on the windows or software.

  • Check any nearby devices that may cause interference.
  • Shut down/switch off the fans, TV, mixtures, blenders, and anything noisy.
  • Keep the mic near and speak directly into it.
  • If you think that the weather is windy, then close the doors and windows.
  • Always make sure that the main cables are not scratching the audio cables.
  • Check if some electromagnetic force around the main cabling is not causing interference.
  • Use specific mics or microphones that are suitable for your needs. The microphone that is attached to your PC can also pick up a lot of unwanted noise.
  • Make sure that the headphones are securely plugged into the computer into the right jack.
  • Generally, all electrical circuits cause noises, but some are louder than others. So, shift to the calmer one by trying different power sockets.

Eliminate the Noise with Software

To stop the irritating sounds coming from the background, you can use different software such as Noise Blocker or Noise Gator that can prevent almost all microphone noise. These kinds of software are free and easy to use. You can use the Noise Blocker for one hour per day absolutely free. Even if you want to use it full time, then also you just have to pay $9.99. The Noise Gator is free but might disturb you sometimes with some bugs. You can try both of these and decide the best one for you!

Reduce the Noise by Cleaning up Audio

If your audio isn’t perfect even after using the software, then you can clean it up with the help of ‘Audacity.’ It’s popular software that can make the sound as clean as possible. To use this software, firstly, download ‘Audacity’ for free and then capture the sound file. Here, make sure to have just one file and not many at the same time.

To add the sound clip, first, click on ‘File’ and then select ‘Import.’ Select the ‘Audio’ button and click ‘Open.’ ‘Click and Drag’ the beginning of the timeline to get an empty area of sound and click on ‘Effect.’ After that, select ‘Noise Reduction.’ Once you do that, you will get a pop-up window on the screen. Now you have to click on ‘Get Noise Profile’ without compromising the already highlighted clear audio. In the final stage, press Ctrl+A and click on ‘Effect’ and then ‘Noise Reduction.’ 

Other Ideas

As mentioned earlier, there are many ways to make your mic not pick up the background noise. Apart from these ideas stated above, you can also use a Mic Preamplifier to ease the transition between two electronic devices. Not only that, but you can also try Power Adaptors as well as Shock Mounts. A ground lift adaptor helps in reducing the static noise, and the shock mount is famous for eliminating the background noise caused by vibrations. Using Wind Shields is also a smart way to cut out unwanted wind interference or heavy breath sounds.
