Final Thoughts
Because there are so many sound-absorbing materials available, it can be difficult to choose the right one to use. If you want to improve the sound quality of a room, rather than soundproof it, you can apply any method on this list. Keep in mind that you can increase their effectiveness by combining multiple methods.
First, a Bit About Sound Waves
If you are combatting too much “noise” in a room, it may help to first understand what your ear is picking up. Sound travels three-dimensionally in waves created by vibration. This can come from a plucked guitar string that resonates, or a person’s vocal cords as they talk.
Every-Day Materials that Absorb Sound
So back to the materials themselves. In a home setting, or places like hotel lobbies, or restaurants, the space is designated for a specific purpose and will likely have functional furniture and décor already in place.

What Makes a Material Absorb Sound?
High absorption materials seem to have two things in common. They are porous and they are dense.
Sound Frequency (Pitch) and Absorption
Before we start looking at specific materials, there is still one more item to discuss: sound frequency. Materials do not absorb and reflect sound of different frequencies equally.
The Sound Absorption of Different Materials
OK, now that we have a basic understanding of how to measure sound absorption, let’s try to actually describe/measure the sound absorption of different materials.
Putting This Knowledge to Use
I would imagine you are reading this article because you want to achieve one of two things:
Sound Absorption in Soundproofing
If you’re attempting to soundproof a room you either have a lot of noise being created inside that room and need to prevent that sound from escaping or you need the room to be protected from outside noise.
Sound Absorption in Acoustics
In acoustics, the goal is not to absorb as much sound as possible. The goal is to reduce the amount of echo in a space to the point where amount of sound distortion is at a pleasing level. This video is an excellent demonstration in explaining the goal of using sound absorption in a room (either for personal comfort or for recording purposes).
Conclusion
Sound absorption is a measure of how much a material reflects the sound that hits it. You should consider the sound absorption of different materials when sound treating a room, but you should also be thinking about sound transmission.
Acoustic Foam
With a high NRC and plenty of aesthetically pleasing options, Acoustic Foam (Amazon) is the choice of a lot of professionals needing the best in sounds option. Not only do businesses use acoustic sound, but people at home are willing to invest since it is pretty affordable.
Acoustic Panels
These are pretty much like bigger versions of acoustic foam, but the shape and materials are a little bit different.
Sound Deadening Curtains
Having acoustic curtains, or sound deadening curtains (Amazon) set up ready to go can be extremely beneficial for those who need sound and noise control as much as possible.
Heavy-Duty Moving Blankets
Thick, dense moving blankets (Amazon) are the best option for people who might need some temporary solution here and there as far as sound absorption is concerned.
Door and Window Sealant

The choice of colours and patterns also contributes to the aesthetics of these panels and they can easily be incorporated within your design and décor. 3. Sound Absorbing Underlay.
How does open-celled foam absorb sound?
Open-Celled foam. Open-celled foam absorbs sound by sound waves moving through the air and passing through the passages of the material. This reduces the sound and generates heat. Porous absorbers are highly effective in reducing mid-range sound frequencies, plus the thicker the material the greater the sound absorption.
How does a fibrous material absorb sound waves?
Fibrous material absorbs sound waves as they can penetrate the surface where they will be bent, dampened and converted into heat energy. Only small parts of the sound waves are reflected back into the room.
Felt
Felt, in the form of acoustic panels, wall coverings, floor coverings, hanging panels, etc, offers great sound absorption along with excellent visual aesthetics. Wool felt solutions come in various sizes and colors and offer excellent muffling of sound due to their soft surface. Felts are produced by pressing and matting fibers together.
Acoustic Foam
Acoustic foam, also known as studio foam, is an open celled foam that consists of a distinctive wedge or pyramid shape and is used for acoustic treatment. They absorb sound waves that reflect off of hard surfaces and are highly effective when it comes to absorbing sound.
Polyester Fiber
Polyester fiber, also known as non-woven fabric, is a man made fiber that consists of long chain synthetic polymers. Since the sound absorption of polyester fiber increases with the frequency of sound, it is most effective at high frequencies.
Fiber Glass
