How to Stop Mic from Picking up Background Noise?: Step By Step a Complete Guide
3-Sources of Noise That You Need to Know
Before we go any further, let me first share 3 different types of noises that can ruin the quality of your recording.
- Wind Noise
You don’t always record audio in a sound-proof chamber, especially when you record a video. There are times you go outside. But the thing is, outdoor recording can compromise the quality of your audio. The wind will generate an extra low frequency when it interacts with your microphone diaphragm.
When the weather is very windy, your mic can pick a noisy rumble. And the noise can dominate the sound of your recording. When the rumble is there, it will jeopardize the quality of your recording.
To prevent this from happening, keep your mic in a sheltered position. Also, consider using the microphone windshield to protect the quality of your audio.
- Ground noise
Ground noise is the kind of noise that is distributed via a physical connection. This kind of noise usually causes when some connected equipment plugs into different power sockets.
Since the ground values for the equipment are different, it can create a buzzing sound. To remove ground noise, you need to plug all the equipment into a single power socket.
- Background Noise
You must have already aware of the background noise. It is any of the sounds that go with the sound of your main source. There are different ways that you can choose to stop your mic from picking up the background noise.
Buying a noise-canceling microphone might be the easiest option to deal with this problem. Unfortunately, a high-quality noise-canceling microphone can cost you more than a hundred dollars.

Similar to the windscreen, a pop filter is also useful to filter the unwanted noise that can ruin your recording. However, there’s a slight difference between the two.
While windscreen is more focused on blocking wind and breathy noise, a pop filter can filter the plosive sounds. Plosive sound is the sound that contains letters such as ‘B’ and ‘P’.
When you use a condenser mic, it is necessary to use a pop filter. A condenser mic is usually much more sensitive than the dynamic mic. Therefore, it is common for condenser mic to pick some amount of background noise.
Usually, a pop filter is placed several inches away from the microphone. There are so many low-cost pop filters in the market. But if you want to get a professional recording result, it will be better to invest in a high-quality pop filter.
The main use of microphone shock mount is to isolate the microphone from transmitting noise. Just like the name, it will protect your mic from shocks and vibration.
Also called spider mounts, shock mounts will provide basic protection to the microphone and prevent it from damage. Using shock mount can improve the quality of your recording.
