One area of acoustics is sound absorption. It is defined as a process of taking in the energy and not reflecting it back. Sound absorption is widely used for soundproofing purposes. Thus, we would like to talk more about it.
Absorption is commonly used to reduce echo in the room, but not block sounds. Therefore, the materials that help absorb sounds are light and fluffy. The products are designed to make the surfaces softer. Interestingly, there is a coefficient that helps determining the absorbing power of a material. However, sound frequency plays a huge role in this.
There is a variety of absorbing materials, but the most generally used ones are the following two:
This is a solution to keep sound from escaping the room, and improve overall acoustics as it absorbs multi-frequency noise. Another advantage of the acoustic foam is that it is extremely easy to install: you simply create seamless absorptive walls.
Acoustic panels are perfect for any general absorption need. They are most effective at fixing acoustics in a single room. Keep in mind that they can be customizable, which is great for aesthetic reasons.
If you realize that you require sound absorption, the next step should be to find out how much coverage you need to solve the issue. For classical noise reduction, we would recommend covering 10-25% of the wall. However, if you think you need some additional guidance, we will be glad to provide you a free acoustical consultation.
