Acoustic Diffuser Placement Guide

If you are looking for a way to improve the sound quality in your room, you may want to consider using acoustic diffusers.

Diffusers can help distribute sound evenly throughout the room, making it sound better overall. 

This blog post will discuss where to place acoustic diffusers to get the best results. 

Acoustic Diffuser Placement

Where to put acoustic diffusers

There are a few different places where you can place an acoustic diffuser in your home or office. The most common ones include: behind or above the speaker and on the ceiling overhead of speakers.

You can also place them on a wall, as long as there is an open space behind it.

Make sure to experiment with different locations to find the best spot for your acoustic diffuser. You may have to move it around a bit until you find the correct place. 

What Is an Acoustic Diffuser and What Does It Do?

An acoustic diffuser is a device you can use to reduce the echo or reverberation in an enclosed space.

A good example of where this would come into play is if you had two people talking in your living room, and their voices sounded like they were coming from different directions. 

These devices are typically made out of wood, but some plastic and foam options are also available. Diffusers work by breaking up sound waves into smaller pieces. 

This helps to eliminate any echoes or reverberations present in the room. It also helps to distribute the sound evenly throughout the space, making it easier for people to hear what is being said.

How to Determine the Best Placement for Your Acoustic Diffuser

When it comes to acoustic diffusers, there is no one-size-fits-all solution.

The best placement for these devices will vary depending on the size and shape of the room and the type of diffuser that is being used. 

However, you can follow some general guidelines to achieve the best results.

The first step is to determine what type of diffuser you have and where it needs to go to be most effective at eliminating echoes or reverberations. 

If you’re using foam panels, they should be installed on the ceiling near corners and other areas where sound waves can bounce off walls without hitting any objects (such as furniture).

If you’re using wood or fabric panels, they can be installed on the walls near corners and other areas where sound waves tend to bounce off.

Once you have determined where your diffusers should go, it is important to measure the space to ensure that the panels will fit correctly.

It would be best to consider the height of the panels, as they should be installed at least six inches away from the ceiling or floor.

It is also important to note that acoustic diffusers will not work miracles, and you should not use them in place of soundproofing materials.

If you are looking for a way to eliminate echoes and reverberations from a room completely, then acoustic diffusers are not the right solution. 

However, they can be a great way to improve the sound quality in a space and make it easier for people to hear what is being said.

The Different Types of Acoustic Diffusers 

There are a few different types of acoustic diffusers available on the market today. Each type has its benefits and drawbacks regarding working in other spaces and budgets.


These devices are relatively inexpensive but may not last as long as other materials like wood or metal. They are also not as effective at diffusing sound waves as alternatives.


Wood diffusers are more expensive than foam, but they can last longer and more effectively diffusing sound waves. They also tend to look nicer in space than foam panels.


Fabric panels are less expensive than wood or metal, but they do not last as long. They are also more prone to absorbing sound waves than other materials like wood or foam.

How to Know an Acoustic Diffuser Is Working Properly

How to install acoustic diffusers and where to place them

If you place an acoustic diffuser in your space and the sound quality is not improved, then it means that the product needs to be replaced or other factors affect its performance. 

Acoustic diffusers should last for years if used properly. You can tell if an acoustic diffuser is working correctly by:

  • Listening carefully (or using a sound meter) to see if the good quality has improved.
  • Measuring the decibel level before and after placement of the acoustic diffuser. 
  • Looking at the frequency response chart to see if there is an improvement. 

If there is no change in these areas, the acoustic diffuser is not working correctly and should be replaced.

Tips on How to Get the Most Out of Your Acoustic Diffuser

Here are a few tips on how to get the most out of your acoustic diffuser:

  • Make sure you place the acoustic diffuser in the right spot. It would be best to put it behind or above the speaker or in front of the speaker on the floor.
  • Don’t expect an acoustic diffuser to work miracles. It would be best if you did not use it in place of proper acoustic treatment.
  • Make sure the space behind the acoustic diffuser is open. This will help disperse the sound waves more evenly.
  • Experiment with different locations to find the best spot for your acoustic diffuser. You may have to move it around a bit until you find the correct place.

Frequently Asked Questions

Why Is My Acoustic Diffuser Not Working Properly?

Yes, acoustic diffusers can work for people with hearing loss. They are a great way to improve the sound quality in your home or office without having to spend money on new equipment or materials.
