Imagine if you are on a con call with your team, discussing something significant, and suddenly you start hearing some disturbing noise! Background or ambient microphone noise can be the most irritating issue and a real pain when you are talking on-call or watching some interesting clips. Fortunately, there are a few ideas that can help you to make mic not pick up the background noise.
How to Stop Mic from Picking Up Background Noise
Before you start reading this article, let me tell you that any sound recording will generate background noise to some extent. This article is all about minimizing the effect of an audio recording. Follow these steps to get rid of disturbing background sounds coming from the mic.
Windows 7, 8, or 10
Step 1: Start your laptop and go to start.
Step 2: Go to the ‘Control Panel.’
Step 3: Open ‘Hardware and Sound.’
Step 4: Select ‘Sound’ and then ‘Recording.’
Step 5: Look for the Microphone bar.
Step 6: Right-click and choose ‘Properties.’
Step 7: Get the Levels tab and fin the Microphone Boost.
Step 8: Keep the dial/arrow lowest on the Microphone boost.
Step 9: Move the dial to its maximum capacity on the Microphone.
Step 10: Go to the tab written ‘Enhancements.’
Step 11: Untick ‘Noise Suppression’ and ‘Acoustic Echo Cancellation.’
Step 12: Press ‘OK’ and go back to ‘Recording.’
Step 13: Test the noise again by clicking ‘Listen to this Device.’
If you use the latest versions of Macbook, then go to System Preferences first and find Sound Preferences. Then, find the Ambient Noise Reduction tool. If the Ambient Noise Reduction box is not ticked, do it. Make it marked and move the dial-up/down until you find the right balance of sound volume and background noise.
Mic 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.’
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.
