WHAT MATERIALS ABSORB SOUND THE BEST
There are many ways to soundproof your space, whether that’s with acoustic panels or filling your room with furniture to reduce the echo. While there are different types of materials that absorb sound, they can only absorb sound to an extent. The best sound-absorbing materials are the ones that absorb most of the sound energy that collides with them. Some materials are more effective than others depending on the type of noise created, noise source, building structure, wall construction, and other key factors. But what material absorbs sound the best? Here are some of our favorites.
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 hard surfaces and are highly effective when absorbing sound. Acoustic foam can be attached to panels, suspended from ceilings or acoustic baffles, or placed in the corner as bass traps.
Bamboo
Bamboo soundproofing is another effective sound absorption option. The softwood, softness, and low density allow it to absorb and disperse sound energy, preventing noise from bouncing off the material. Porous wood, like bamboo, adds to its ability to absorb energy.
Felt
Felt, in the form of acoustic panels, offers great sound absorption. Wool felt can come in different sizes and colors and absorb sound due to their soft surface. Felts are produced by pressing and matting fibers together. Their ability to bend to uneven surfaces is great for someone who wants to focus on the aesthetics of sound absorption.
Cotton
Cotton is an excellent acoustic material that achieves multiple effects. Cotton soundproofing materials can absorb, disperse, and even contain sound. This natural material is effective because it’s porous and full of channels that accept and contain energy. Cotton is also compactable, so designers can form it into thick sheets that ensnare and disperse sound.
Sound-absorbing materials each have their advantages and disadvantages. Whether you want something aesthetically pleasing or all-natural, there’s something to choose from for everyone. There are acoustic solutions for offices, home theaters, gyms, or any space you want to reduce echo.
