White noise is essentially random noise with a flat spectral density. In simpler terms, noise with the same amplitude, or intensity, in the audible frequency spectrum — is known as white noise. White noise gets its name from the fact that it resembles white light, which is a blend of all visible wavelengths of light. White noise or background noise can be quite irritating to the ears and this is something that can be solved. White noise or background noise can be irritating to the ears. Find out some effective solutions about how to get rid of white noise in mic.
While white noise is a great thing for people who have trouble falling asleep, it is generally unwanted by people who are filming something. Unfortunately, most mics tend to pick up background noise which can ruin your audio quality. This is why, after conducting extensive research, we have compiled a list of methods that you can use to get rid of the annoying white noise that gets picked up by your microphone.
1. Adjust the Gain
The gain setting is to account for static noise in most of the cases. On your mic, look for the “gain” or “input” knob. Reduce the volume by 1-2 dB (decibels) and try speaking into the microphone again to see if it improves. Continue adjusting the volume until the static noise has faded completely.
Gain refers to the sensitivity of your microphone. The higher the gain, the louder the microphone’s output volume would be. The microphone can pick noises from the background and can also maximize it into static if the gain is set too high. The strength of the microphone and the diaphragm of the microphone are all factors.
2. Secure the cables
Static noises are sometimes triggered by a jack or cable that is not properly seated in its outlet. Push the cords connecting your microphone to make sure they’re completely plugged in. If one of the cables is moving around, it may need to be replaced to eliminate the static.
3. Change the distance between you and the mic
When you’re speaking into a microphone while still transmitting audio out of an amplifier or speaker, shifting your position will eliminate feedback. Other electronics’ low- or high-frequency sounds may sometimes trigger audio static. If your phone, the TV, or any other audio equipment is close to the microphone, it should be moved away. This will help eliminate white noise
4. Get rid of ambient noise
If you’re recording at home and you’re getting static, you can try soundproofing the room. There are many ways to do that. You can put soundproofing foam on the walls or use tapestries and carpets to insulate the walls and floor. Hanging curtains on the walls and using boards that are soundproof are also effective for reducing noises in the room.
5. Invest in a pop filter
A pop filter is a small screen that protects your microphone and helps to eliminate popping and hissing noises from p-, h-, and t-sounds. Purchase a pop filter and mount it just below your microphone on the mic stand. Then, using the flexible part, set the fabric or metal filter between your mouth and the microphone. Any static caused by the words you speak into the mic will be removed by pop filters.
- What is a Pop Filter and Why Do You Need It?
Pop filters are very useful. Using a pop filter eliminates problems on both the high and low ends of the spectrum, allowing for easier recording editing and, as a result, better-sounding demos, auditions, and finished work.
A pop filter has two functions. Its primary function is to eliminate “popping” noises when singing or speaking into a microphone. The sudden air pressure causes the microphone to overload when we say words with ‘plosives,’ such as ‘people’ and ‘pain,’ both of which have a ‘p’ in the word. This can contribute to the static white noise heard in recordings.
To help eliminate this fast moving air, pop filters are placed in front of the microphone.
6. Utilize shock mounds
Modern microphones are very sensitive to background noise and are susceptible to picking upon them. Shock mounts are an effective way to shield your microphone from vibration and shocks while also maintaining optimum output and quality of sound. The use of a shock mount effectively eliminates mic handling noise. Using these mounts on stands is highly effective for removing background noises that occur in the background.
7. Use filters to remove static
The audio input signal cannot be modified or inserted into new frequencies by filters. Filters are commonly used to prioritize signals in a particular frequency range. It’s effective for rejecting signals that are from other frequency bands, just as those associated with background noise and unwanted microphone sounds.
A filter for cutting out background noises should be used to eliminate DC offset and rumbles of lower frequency. If you just want to remove the DC offset, fix the frequency control to 10 Hz. AC hum can be quickly eliminated using a notch filter with a cutoff frequency of 60 Hz or 50 Hz.
8. Use a noise gate
A noise gate is generally used to help minimize background noise and reduce unwanted external noises. Only when an audio signal exceeds a threshold value is it allowed to pass through. In other words, it’s commonly used when the audio signal is louder than the background noise. The noise gate can eliminate steady noise static from the amplifier as well as hum from the power supply system and power cable if properly set without affecting the sound source. With only a few tweaks and the aid of the gate, you can remove unnecessary background noise or static picked up by your microphone, whether on stage or in your home studio.
While the presence of static or white noises is in the background is something we usually do have control over, we can surely take certain measures to get rid of them. We hope this article helped you find the right solution to your problems so that you can make your recordings in peace.
