Wondering why your microphone produces that irritating echo noise?

Here is a simple guide to understanding what causes the echo and expert tips on how you can fix the echo once and for all.

You can use microphones for different occasions and in different settings.

This can either be indoors or outdoors.

Besides, there are multiple types of microphones that you can use occasionally.

Also, these can be broadly categorized into inbuilt factory microphones or aftermarket microphones.

Regardless of the type and purpose, you will encounter that annoying feedback loop when using the microphone.

Therefore, how can you troubleshoot the problem and fix the problem?

No need to worry anymore because I got your back in this. So, let’s jump in!

Troubleshooting the Problem

Determining the course and source of the echo is as good as solving the problem.

An echoing sound is formed when output sound from your speakers travels back into your microphone.

This can happen repeatedly resulting in a loop of continuous echo noise.

Technically, echo is caused by microphones and speakers.

Another major cause is your environmental setup.

Below you will discover the details of what causes microphones to echo.

1. When Microphones are Close to Speakers

When microphones are too close to an output speaker, it becomes easy for the microphones to pick back the sound that is coming from the speaker.

When this happens, a feedback loop is created resulting in the echo sound.

2. Too Much Hard Surfaces

Since hard surfaces are not good at absorbing sound, they become susceptible to creating a rebound surface.

When sound from the speakers hit these surfaces, the sound bounces back into the microphone causing the echo sound.

3. Microphones Susceptible to Echo

Microphones operate in different forms of technology.

These include; omnidirectional, cardioid, hyper-cardioid or shotgun.

Moreover, the essence of the technology is to aid with picking sound as it comes into the microphone.

Omnidirectional microphones are designed to pick sound from a 360-degree surface area.

This implies such microphones can pick all types of sound including what is not needed.

When this happens, echo sound is just an avoidable.

4. Inbuilt Factory Microphones

You will encounter this more if you use your inbuilt laptop, phone or desktop computer microphones.

One particular reason why this happens is that such microphones are not sturdy enough to handle sound variations.

Also, since the microphone and the speaker are just within the same device, the probability of rebound noise increases.

A continuous flow of this noise back into the speakers leads to the echoing sound.

7 Tips for Fixing the Echoing

Now that you know what causes microphones to echo, it’s time to fix the problem so that you hear the irritating sound no more.

Moreover, you need the quality of the sound uncompromised during a recording or a public speech.

1. Determine the Source

First, you need to know where the echo is coming from.

To do this, you can switch off one microphone at a time especially if you have multiple of them.

Muting and testing help in determining the specific microphone (s) causing the echo.

2. Use Specialized Headphones

If you are in a conference call and getting some echo sound.

There’s a high probability that it’s because you are relying on the inbuilt microphone that comes with your device.

The beauty of having a specialized headphone is that the sound will have a focus point.

Also, using headphones helps in avoiding unwanted background sounds.

Besides, having a headphone is important as you can monitor the sound for any echo and correct the problem on time.

3. Use a Different USB Port

If you are using aftermarket USB microphones and getting the echo, you should try changing the port you are using to another.

To do this, you only have to unplug the microphone from the initial USB port into another.

Sometimes the echo is due to poor USB configuration.

4. Move the Microphone

When the microphone is too close to the speaker, a feedback loop is easily created which results in the echo.

To avoid this, you can move the microphone away from the speaker until you can’t hear the echo.

5. Control the Volume

And when the echo becomes too much, you should try turning down the volume.

When the volume is low, the microphone will only pick the sound that is in its immediate surroundings.

This is the complete opposite when the volume is high.

6. Use Specialized Microphones

Your choice of the microphone has an important stake to contribute to echo production.

Therefore, you should avoid omnidirectional microphones that can pick sound waves from all directions.

The problem with this is that the microphone will pick even the unwanted sound.

What you need is a cardioid, hyper-cardioid, or a short gun microphone.

These microphones are designed to focus on picking the right background sound from one-directional.

7. Acoustic Studio Setup

Being in an enclosed room with no additional objects is a major cause of microphones to echo.

This is because, with no objects to absorb the sound, it will bounce back into your microphone.

To solve this problem, you need to add more objects to the room.

Some of these include; carpets, moving blankets, sleeping bags, and couch cushions.

Adding these objects in the room help to soften the room by providing surfaces that can absorb the sound.

Final Thoughts

Its true microphones can cause an echo.

The good news is that the problem can be avoided before it happens.

After all, what you need is a quality audio sound that is free of echo regardless of your environmental setup.

The first step to preventing echo is getting yourself quality microphones.

What you need are microphones designed to pick only the right sound while filtering out the unwanted one like an echo.

However, if the problem is already in the docks, the best you can do is to control it.

You can move the microphone away from the speakers, turn down the volume, use headphones, or switch USB ports.

Lastly, you should soften your indoor areas with objects such as cushions, carpets, and sleeping bags to absorb sound that would cause the echo.

As you can see, the guide is simple to follow, right from troubleshooting to coming up with the solution.

So, it’s time to take action and take care of echoes from microphones. Cheers!
