Different Types of Materials for Acoustic Panels

Looking for a way to improve the sound quality in your home or office? Acoustic panels may be the answer!

Many materials can be used for acoustic panels, and each has advantages and disadvantages.

This blog post will discuss the pros and cons of three popular materials: polyester/felt, foam, and insulation (Rockwool or fiberglass).

Let's get started!

What Are Acoustic Panels?

Acoustic panels are panels that are used to improve the sound quality in a room. They do this by absorbing and deflecting sound waves. This is done using various materials, including fiberglass, mineral wool, foam, and wood.

Acoustic panels can be used in several applications, including bedroom content studios, home offices and home theaters. They can help to reduce echoes and reverberation, as well as improve the clarity of sound, especially when audio is important to your work (like zoom calls or recording audio).

Materials For Acoustic Panels

Several different materials can be used for acoustic panels. Each material has its advantages and disadvantages.


Polyester or felt acoustic panels are a popular choice for many people. They are made from various materials, including polyester fiber, wool, cotton, and bamboo.

Polyester/felt acoustic panels are known for their ability to absorb sound. They are also relatively inexpensive and easy to install. However, they are usually thin and don't absorb sound as well as thicker material.


  • Absorbs sound
  • Inexpensive
  • Easy to install
  • Can be created in interesting designs


  • Not as absorbing as some other options
  • Most options are relatively thin - need a thicker panel for maximum sound absorption


Acoustic foam panels are one of the most popular materials used for mid and high frequencies. It is effective at absorbing sound and is reasonably inexpensive. Various foam materials can be used for acoustical foam, including wedge foam and pyramid foam.

It is important to consider the thickness of the foam when selecting it for acoustic panels. Thicker foam will be more effective at absorbing sound, but it will also be more expensive.

In general, thicker foam is better for absorbing bass frequencies and unwanted noise, while the thinner foam is better for absorbing low-frequency sounds.


  • Soundproofing foam is inexpensive
  • Effective at absorbing sound
  • Best to reduce the sound energy
  • Available in a variety of thicknesses


  • Not as durable as some other materials
  • Can be flammable

Insulation (Rockwool or Fiberglass)

Rockwool and fiberglass are two types of insulation used for acoustic panels. They are both very effective at absorbing sound and are relatively inexpensive. However, they can be difficult to install and require some sort of container to hold the material. Many acoustic panels that include rockwool or fiberglass are built with a wooden frame, and then loaded with the material on the interior.


  • Inexpensive
  • Effective at sound deadening
  • Great sound absorption at  lower frequencies


  • Difficult to install
  • Can get very expensive, especially if bought off the shelf

How to Choose The Best Material

When choosing the best material for your acoustic panels, there are a few things to consider. Here are a few tips:

  1. Consider the purpose of the acoustic panels. Are you using them for a home content studio? A home office? A bedroom studio? The intended use will help to determine the best material.
  2. Consider your budget. Acoustic panels can range in price from $30 to more than $200 per panel. The more "live" your room is, the more panels you will need.
  3. Consider the sound absorption. What frequency of sound do you need to absorb? Most home recording studios and home content studios don't need as much bass absorption because the speakers are not as big, but if you have speakers that are more than 7", you may want to consider bass traps.
  4. Consider the installation. Some materials, like insulation, can be difficult to install.

Acoustic Panels Work

No matter what material you choose for your room acoustics, you'll be sure to improve the sound quality in your space when you use acoustic panels. It always pays to consider the material when making your decision, as the different options can impact your budget and your aesthetic.
