How To Fix High Pitch Noise From Microphone: All You Need To Know

Microphones are pretty common in today’s life and have made life easier. High pitch noise is a common issue in microphones. Every person across the world has experienced it at least thrice in their lifetime. 

There are several causes and things that you should consider when you hear the noise. These include things like volume setting, hardware, drivers, cables, and many more. 

Now, if you own a microphone and it makes this noise, do not worry. It’s something that you can quickly fix. 

In this article, I will highlight all the probable causes of this issue and solve them. Let’s get back to the commonly asked question. 

How to Fix High Pitch Noise from Microphone

At times the microphones might be overused or are not correctly stored. The speakers will therefore not meet the basic requirements of the work. 

This will lead to poor-quality sound. The microphone and other equipment should be appropriately cleaned and checked regularly and timely. 

Please do not leave the microphone connected to the laptop or console when you are not using it. It’s because even when the microphone is off, electric current can still pass through them.

Find Out The Problem

The one thing that you should know is that you have to know the cause of the high pitch noise from your microphone. After identifying the issue, it’ll be easy to fix the issue. 

Determining the cause can be pretty tricky, but once you get there you are good to go. Ensure that the microphone is not old, worn out, or defective. 

If the gear is broken and cannot be fixed in any way, the microphone can make a high pitch noise. 

You can find the issue relatively quickly by checking the cables, power supply, isolation, electromagnetic, and many more. In case it’s any of these, you can quickly fix the issue. 

The Cause Of High Pitch Noise And The Possible Solutions

If your microphone is not faulty or broken in any way, there’s another issue causing the high pitch noise. 

The goal is to find the cause of the issue and then fix it. In this section, we have highlighted some of the causes of high pitch noise on the microphone.  

Cables 

If the microphone you are using does not connect directly to the computer via Bluetooth or any other connections, then it indeed uses several cables. 

Check the cables that connect the microphone and the audio source to determine if they are in excellent condition. 

Look for holes, leaking airs, and rips on the cables; these may be the causes of the high pitch voice. Ensure the cables and the computer’s power supply on the ground do not run across each other.  

High Microphone Volume

The microphone volume is another thing to look at. If the volume is too high, then it might be the cause of high pitch noise. High volume bounces back and causes the high pitch noises.

Grounding

Grounding is a sensitive factor. Check both your computer and audio interface grounding. You will be able to determine whether an electric discharge is occurring or not occurring. 

Drivers

The new driver updates might be because of the high pitch noise. You need to uninstall the driver you installed or downloaded and then reinstall the driver. 

It might help solve the noise. Again if the drivers are not up to date, it may cause high pitch noise. You should install updates and check if the noise persists. 

Power Supply Issue

Without power, your microphone cannot function. So be sure to take a look at your microphone. The power supply is where your computer and the mic are connected through. 

It offers the necessary power to your device. If the power supply is not stable or has something wrong, you might hear high pitch noises. 

Electromagnetic Interface

You should check the electromagnetic interface. The high pitch noise can be because your device has an overload of electricity from other components. Therefore, you should fix this by unplugging some devices that use different power sources from the microphone. 

Inside Hardware

Confirm that the hardware inside the microphone is functioning normally. At times it might be defective or overworking. Fixing the hardware issues can be tricky, forcing you to buy a new microphone.

Poor Isolation of the ADC or DAC

The ADC initial stands for Analog to Digital Converters, while DAC is Digital to Analog Converters. The ADC works in its unique way. 

It offers analog signals over the input voltage. It then changes the signals to digital representations. 

The DAC and ADC do offer different functions for the microphone. Therefore you should never use them on the same power source. This will undoubtedly cause sound distortion.

Additional Causes For High Pitch Noise

As mentioned earlier, high pitch noise can be so irritating. Be it in a concert or event. At the time, the cause could be the volume difference between the headset and the microphone. 

In such a case, when the microphone’s volume is relatively high, it can create high pitch noises. The noise is known as a feedback loop. 

Another cause can be the wrong settings of the speaker. It creates unnecessary high pitch noise at any frequency. 

The noise starts low but gets louder and so irritating with time. If you place the microphone too close to the speakers, this can certainly happen. 

Using poor instruments can be a cause too. This includes cheap or destroyed instruments. For example, if the microphone’s plug is rusty or the wires have damages, this can cause the issue. 

Plugging in the microphone too near to the external sound device is another common issue that should be avoided at all costs. It causes a high-pitched voice in the background. 

Solution For High Pitch Noise

If you are using a microphone and it starts producing high pitch noise, turn the microphone immediately. After this, hold it from some distance to your mouth. 

Cover the microphone entirely with your hands. This will certainly stop the acoustic feedback. 

You then point the microphone in a different direction and ensure that the equalization of the special gadgetry and acoustic system is excellent. 

Dealing with a microphone is not as easy as it looks. It would be best if you found an operator that has enough experience. Primarily the microphone produces a humming sound when you turn it on for the first time. 

The operator should be able to understand and know this. The operator should be quick to turn the gain before the microphone begins to howl. 

However, this is also dependent on the speakers’ position and how the microphone is held. The operator should be keen and quick to notice any sudden unnecessary feedback and fix it before it ruins everything. 

Directional speakers are great too. However, when using these speakers, the mic can only be behind or beside the speaker. 

Never should you put the mic in front of the speakers. Again you should avoid directing the speakers in areas that can reflect sound like walls. 

Always unplug the microphone when no one is using it. The way you use the microphone also matters. Speaking with the microphone close helps to reduce the noise brought by feedback. Reduce the speakers’ output so that the microphone does not pick unnecessary noise from the speaker. 

Direct injection is excellent for musical injections. Do not use microphones. Using the digital feedback eliminator is also wise and so practical. 

It reduces the chances of experiencing feedback loops. This device comes in different models that have various effectiveness levels. The better ones that are undoubtedly high priced offer better results. 

At times people do experience the high pitch noise when recording. The issue is more common when one is using a mouse. 

Here is a little trick to confirm this. Use your microphone and the mouse without speaking or doing anything. Listen to the recording later, and you’ll notice some noises in the background. 

Primarily the source of the problem is that your microphone is always plugged close to your external noise. 

The problem is so common when using a laptop device. Unplugging the mouse and putting it on a different port will solve the high pitch noise.

Conclusion

High pitch noise can be so irritating. It can be extra annoying when you record for hours, and then at the end of the whole process, you find out that the mic has been producing high pitch noise. 

You might get irritated to the point of thinking there is nothing you can do to fix the issue. You might even think of purchasing an expensive microphone that is not prone to such problems. 

In this article, I have highlighted some of the causes and how to fix them.  The causes of high pitch noise in microphones are several. 

There are also various solutions to the issue. First, you have to identify the problem by finding the source of the high pitch noise.
