Why Does Cork Absorb Sound?
If you reside or work in a noisy neighborhood and you have looked for ways to cut out this noise, then you most definitely have stumbled on one unique way – by using corks. Soundproofing using corks is becoming more popular among folks and office workers, but that doesn’t make it seem any less funny. “How can that little thing from a wine bottle impede the flow of sound?” you may think. Well, we will tell you more about it in this article.
Do corks absorb sound?
Yes, they do. Although not as effective as mineral wool or cellulose, corks can to no small extent trap-in and reduce the level of noise in a room or office. Corks can aid in the absorption and dissipation of acoustics to lower distortion level and improve the tone retaining capacity of a place.
Corks reduce the level of scattered acoustics in a room by absorbing the vibrations from whatever noise made in the room. You can make rooms quieter by putting materials made from it, like cork flooring boards, in different strategic places inside the room.
Why do corks absorb sound?
Corks are quite powerful natural echo absorbents. This property is as a result of their cellular structure. The cellular structure of corks is over 50% air and comprises of millions of 14-sided air-sealed cells in the form of a honeycomb structure. This composition makes it an excellent insulator and very light too. Also, because it is mainly full of air, and air is another strong insulator, it can impede the passage of acoustics successfully.
For audio to pass through correctly, the audio waves have to be long and intense. Corks effectively prevent this by using their cells as a barrier to break and take-in or diffuse the particular audio.
Where can you use cork for noise insulation?
Corks can be used for absorbing acoustics in almost every space. Places, where you can use corks for soundproofing, include house apartments, condos, and commercial areas like office buildings, hospitals, music recording studios, gyms, theaters and also spas and therapy homes.
Whether you need to do some insulating in your home or place of business, look to corks for the answer and a great deal.

It is also the best of acoustic absorbents that exhibits desirable qualities such as high durability and can be easily maintained without wearing off.
Corks, by default, dampen noise, and with new designs have been taken up in buildings as among the best ways to get soundproofing done in an appealing manner.
- Cushioning properties
Moving around on a surface floored with corks is very comfortable as the shock waves are absorbed in the expansion and compression of the flooring because of the air volumes in it, giving a cushioning effect.
It is also an excellent way to insulate walls with comfort. Making use of corks for the insulation will lower the amount of noise that passes through the building considerably.
- Health benefits
Using corks to reduce unwanted noise appear to have excellent health benefits. The real cork is made from a material that is highly anti-microbial.

- Environmentally Beneficial
Corks are also Eco-friendly. They do not take in dust and also do not retain dents.
Corks have excellent soundproofing properties. This increasingly popular insulator is waterproof and is also used as stoppers for bottles, floaters, gasket materials and wall coverings.
They are excellent insulators, for both acoustics and electricity, and are used in all kinds of places. This fantastic material also possesses other benefits that make it the best choice for noise absorption and office or home insulation.
