Natural Resources That Absorb Sound

Natural Resources That Absorb Sound
August 05, 2022

Using soundproofing materials to create peaceful environments in indoor spaces is great, but so is treating the natural environment with care. Fortunately, it’s possible to do both at once. Soundproof Cow uses sustainable soundproofing solutions. Today, we’ll cover some of nature’s most effective soundproofing resources.

Nature’s Soundproofers

Mother Nature can compete with some of the most innovative manufacturers, providing several naturally occurring substances with excellent acoustic properties. Some of these organic soundproofing materials include:


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, which means it’s 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.


Bamboo soundproofing is another effective sound absorption option because it’s a soft type of wood. Bamboo’s softness and low density allow it to absorb and disperse sound energy, preventing noise from reflecting off the material. It’s porous, too, which adds to its ability to absorb energy. Some homeowners plant dense bamboo walls around their property for natural sound absorption.

Coconut Fibers

Coconut husks are another porous, fibrous material source that occurs naturally. As a result, coconut fibers share similar soundproofing properties with cotton and bamboo. However, coconut fibers are lighter than cotton, so it takes more to produce an effective soundproofing material.

Eco-Friendly Acoustic Products

Soundproofing companies often use nature’s effective soundproofing materials when developing products. Some of Soundproof Cow’s best products featuring naturally occurring materials include:

Echo Absorber Acoustic Cotton

Echo Absorber Acoustic Cotton is an environmentally friendly acoustic material that interacts with high, low and middle frequencies. This product line features 80% recycled materials while skipping volatile organic compounds (VOCs) and harmful substances like formaldehyde.

As cotton-based acoustic treatments, Echo Absorber products prevent sound from bouncing around a room. Rather than echoing or reverberating, sound waves dissipate when they collide with the cotton fibers. Our Echo Absorber line is versatile and easy to cut to size, making it a popular acoustic material for auditoriums, gyms, gun ranges and other noisy areas. At Soundproof Cow, we carry two types of products that feature Echo Absorber Acoustic Cotton:

Quiet Batt Soundproofing Insulation

Quiet Batt™ Soundproofing Insulation is another cotton-based material that reduces echoes and reverberations. You can slide acoustic insulation products between walls or inside a dropped ceiling to absorb sound upon impact. This material also has noise dampening properties, meaning it will inhibit sound’s ability to pass through surfaces and enter other rooms.

As another benefit Soundproofing insulation interacts with other types of energy — namely heat. Installing Quiet Batt™ Soundproofing Insulation will keep your home warm in the winter and cool in the summer.
