No one likes high-pitched noise for the sole reason that it is very irritating, especially when you have been recording for hours using your microphone and at the end, you find out that your microphone has been making high-pitched noise all along.
I understand that it gets very frustrating and you feel as if there is nothing that you can do to fix it except getting rid of it and buying yourself an expensive microphone. But before you that, I suggest that you give this article a read, I am sure that you will not regret it.
If a microphone makes constant high-pitched noise, it doesn’t necessarily mean that it is broken, it can also mean that some adjustments need to be made in your equipment’s settings.
Solution for a high pitch from Microphone
When in such a situation immediately turn off the mic or keep it at a distance from your mouth and cover it completely with your hand or any other thing that you can find. By this, you will break the acoustic feedback of the mic with speakers. Point the mic in a different direction. You need good equalization of the acoustic system and special gadgetry.
The operator should be well experienced. When the mic is turned on, it creates a humming sound at the start; this is a post feedback loop indication. The operator can turn the gain before it starts to howl. This depends on the position of the speakers and the area where the mic is to be carried. The operator should be all ears so he can stop the sudden feedback if it occurs.
We can use directional speakers in which the mic is beside or behind the speakers and not in front of them. The speakers should be avoided to be directed in reflected places like walls. If the person holding the mic is experienced, he can unplug the mic or cover it to avoid a feedback loop.
The mic should be unplugged when not in use. Speaking close to the mic can also reduce the feedback. The output of the speakers should be reduced so the mic doesn’t pick it up. A headset or ear-in monitor should be used instead of a speaker monitor.
Musical instruments should use direct injection feeds instead of microphones. A Digital feedback eliminator is also an effective option. They lessen the chances of feedback loops. There are different models with varying levels of effectiveness. The better ones are known to produce good results.
Sometimes we get a high-pitched whine when recording with a microphone. When you play the recording, a high pitch will be whining in the background. It is especially prevalent whenever you move the mouse around. When you listen to your microphone without having to record something using a general sound recorder, you want to search for sound.
Then you go to the sound at the control panel, click on recording, and double-click on the microphone and you can click listen to this device option. After applying, everything you speak through the microphone will come through the speakers.
The source of this problem comes from having your microphone plugged in very close to an external mouse. This is a problem you usually face on a laptop device. If you just unplug the mouse and plug it on a different USB port, the high-pitched whine will go away.
Cause for a high pitch from Microphone:
Everyone feels irritated when they listen to high-pitched sounds on big speakers at an event or concert. In most cases, it is due to the volume difference between the microphone and headset. On stage, when the volume of the microphone is too loud which feeds back and creates sequels of high pitch.
This is known as a feedback loop. It is a ringing noise present in sound systems caused by a looped signal. An infinity loop starts when you speak in the mic, it outputs your signal to the speaker but because of the volume variation it amplifies it again and again and the mic picks up the same signal, again and again, creating a loop.
This sound is feedback caused by the wrong speaker settings. It can be caused at any frequency. This most likely creates disturbing high-pitched sequels which start low and then keep getting louder until it gets unbearable. The most common cause is if it is too close to the speakers.
The frequency which causes more trouble not only depends on the situation but the frequency response of microphones, the characteristics of the instruments used, and the conditions of the room’s resonant frequencies.
Feedbacks can be intermittent. For instance, if you turn down the microphone volume level to stop the continuous feedback. But you can still listen to a mild humming or unpleasant tone when someone’s talk on the mic.
Another reason for the high pitch sounds is the use of the poor instrument. The mic’s plug can rusty or the damaged wire can be also the cause of this problem. If the microphone is plugged near and an external device, a high-pitched whine is produced in the background.
Sometimes instruments are overused or carelessly equipped. They do not meet the requirements of the work, hence, a poor quality result obtained. The pieces of equipment should be checked timely and cleaned properly.
They should not be left connected to the console or the PC when not in use, because even when turned off, there is a chance that electric current is flowing through them.
Now you know how a microphone works and why it produces high pitch noise. So, using this information, now you can fix your problem and get clear and uninterrupted sound for your recordings and your streaming.
