Types of Unwanted Sounds

  • Mic noise are often defined as “unwanted sound”. Basically, the duration and level of the background sounds determine the characteristics of noise. There are 3 main noise types.
  • Broadband Noise (or continuous noise) is that the noise during which the acoustic energy is distributed over a good range of frequencies because it is picked up by a microphone. The seems like hiss and static noise belong during this category.
  • Narrow Band Noise is restricted to a narrow range of frequencies. this type of noise features a constant audio level usually caused by incorrect grounding and poorly shielded cables connecting Narrow Band Noise is essentially any unwanted signal that is still steady over time.
  • Impulse Noise includes sharp sounds like clicks and pops during a mic. it’s a high frequency and short duration.

How are you able to Reduce ground noise on a Laptop or Computer Microphone?

  • If you’re employing a laptop or personal computer to record sounds, you’ll manually enter the device and control the extent of ground noise that your device picks up. samples of ground noise that you simply may find pervasive on microphone input from a laptop or desktop include keyboards, the laptop fan, clicking from the mouse, and more. How you adjust the ambient sound setting for your computer depends on your OS .
  • If you’ve got a Windows system, you’ll use the instrument panel to travel to Hardware and Sound.

  • After you’ve adjusted the microphones, attend the Enhancements tabs to form sure the acoustic echo cancellation box and therefore the noise suppression box are checked. to see the noise, return to the recording menu and hear the device.

Tips To Stop Microphone From Picking Up Breathing

Other than placing your microphone correctly, here are a few other things that you can do to make sure your recording is free of any breathing sounds.

1. Use a Pop Filter

The easiest way to prevent these plosives and breathing noises from ending up in your recording is through something called a pop filter. You can find a good condenser mic and pop filter online (Amazon) to help give you the most professional sound.

This device is used to slow the air that comes from “plosives.” A plosive is a word that causes a rapid rush of air to hit the microphone. A pop filter softens the sound of a plosive, such as words that start with the letter “P” and “B.”

2. Control Your Breathing

Professional artists train in breath control so that they can deliver vocals without making breathing sounds. They do this by controlling their breath, using the mic properly, and breathing through their nose instead of using the mouth.

Try to relax and stretch your upper body before beginning recording to reduce the need for oxygen. As a result, you’ll take fewer breaths.

3. Speak Slowly

When recording, don’t rush your words. Speak slower so you have more time to inhale and exhale which will make you take softer breaths and will allow you to control them better.

4. Maintain Good Posture

Bad posture causes tension in your upper body and restricts your lung capacity. Keep your back and shoulders straight to allow better airflow into your lungs and reduce tension.

5. Don’t Make Sudden Movements

Be careful not to move the microphone or your head suddenly and hold the microphone consistently every time you use it.

6. Use a Sound Editor Program

If the unwanted breathing or other sounds are just in a few places in the recording, you can go through using a sound editor program to find and adjust those sections. When the unwanted part comes up, don’t cut it out or use complete silence. Instead, reduce the volume to eliminate the distraction and still keep the recording pace intact.

7. Use a Noise Reduction Filter

It may be possible to use a noise reduction filter to remove unwanted noises. There are noise reduction filters to remove breathing sounds, clicks and pops, and de-essers to remove the hissing sounds. A low-pass filter may help remove breathing sounds.

8. Pick a Cardioid Microphone

Use a cardioid microphone that has a tight sound pattern. This limits the recorded sound to a smaller area in front of the mic, where it can pick up sound. The cardioid sound pattern is a heart-shaped area that extends from the front of the mic.

This type of microphone is unidirectional. This means it only picks up sound from one direction in front of the mic.
