How to Fix High Pitch Sound Noise

Part 1. Why is Sound High Pitch?

Technically, a sound can acquire a high pitch or squealing sound due to the high frequency the sound got. Since pitch refers to the level of the sound, whether it is high or low when it appears to our ears, then the higher the level of frequency, the higher the pitch is. So, what factors bring a sound high-pitched? Although it all comes down to how the sound waves are generated, literal sources still cause the problem, and they are listed and elaborated on below.

◆ Microphone

As mentioned above, the microphone is a big factor that causes very high-pitched sounds. Therefore, always check the volume of your mic before using it to prevent an ear-cracking whistle and echo from the device.

◆ Musical Instruments

When musical instruments have parts that vibrate quickly, they create music with high pitches. One example of this is the high-pitched guitar, which produces intense vibrations when its thin, shorter strings are plucked

◆ Cables or Wires

If you are using a microphone with many cables, you must inspect the condition of the wires that connects the microphone to your amplifier or speaker. If these connectors have damages, such as rips, holes, or any air-leaking part will cause squealing noises. Also, you must ensure that the cord of your mic does not cross over your device’s power supply because it can be a flaw that can produce high-pitch noise on your sound after recording it.

◆ Computer Drivers

If you are using your computer to record, you must check your PC’s drivers, a common source of a high-pitched sound. If so, you must erase, redownload, and reinstall the audio driver to fix the problem.
