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.

  1. 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.

  1. 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.

  1. 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.

With the current advancement in technology, many people use their phones for more than just making calls and sending the text. Still, we all use this basic function of the phones.

But you can’t just rely on the built-in noise cancellation on your phone. It is because it wouldn’t filter the background noise very well. Thus, you need to consider using an app to filter out the unwanted background noise.

There are more than a few noise cancellation apps available on the market nowadays. One of the best noise-canceling applications out here is Krisp.

This app works by using AI to clean up your audio. Krisp will create a protective layer between your microphone and the app you’re using to filter out the background noise.

Unfortunately, Krisp doesn’t work on Android. It only works on iOS. But you can use it on your PC since it works for both Windows and Mac. So if the above ways don’t solve your problem, you can try to install Krisp on your PC

Here are 5 steps to easily set Krisp on Zoom

  2. Open “Setting” then select the “Audio” tab
  3. Select “Kris Speaker” from the speaker drop-down list.

Microphone Accessories to Optimize Recording Quality

Other than using software to cancel background noise, you can also use microphone accessories to reduce background noise. Here are some of the accessories you can use.

Microphone Windscreen

Microphone windscreen made from a foam material. It is useful to protect your microphone from dirt and moisture. But other than protecting your microphone, the windscreen can also help to remove background noise.

By covering your microphone with a windscreen, you can filter out the unwanted sound. The quality of your recording will increase since it filters out the unwanted noise.

The kind of noise that it filters includes breathy sound, clicks, pops, or hiss sound. So if you want to produce a high-quality recording, you better make sure that there’s a windscreen snuggle on your mic.

 

Pop Filter

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.

Shock Mount

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.

Usually, a quality manufacturer will produce a dedicated shock mount for a specifics microphone model. This is important to allow maximum shock absorption of the noise.

So if you want to make a rumble-free recording, find a dedicated shock mount for your particular mic model.

 

How to Produce a Clean, High-Quality Audio

To produce a high-quality audio recording, there are some basic things that you need to ensure.

Record in Quiet Environment

If you are using a condenser mic to create the recording, then you need to make sure that you are in a quiet environment. These are essential requirements for this type of microphone.

Because condenser mic is very sensitive and able to easily pick the sound of your environment.

So if somebody around you is clapping or laughing, the mic will pick up the sound, even if the person is standing behind the mic.

The thing is, sometimes we don’t always notice the sound in the process of recording. But once you do the editing, you can hear a slight buzzing noise.

To determine if your environment is quiet enough for you to make a recording, take a walk around your room with your microphone.

Make sure you amplify the gain of your microphone before starting. Then listen to the result through your headphone. If there’s any interfering, you will be able to catch the sound.

Check the Condition of Your Cables

Other than checking the environment, you also need to check your cables shield and connector. It’s not necessary to buy an expensive cable, but you need to make sure that the cable has a proper connector and shielding.

Ensure that your cable is in good condition. If there’s any damage to the cable, it can cause sound pollution and affect the quality of your recording.
