What kind of foam is used for acoustic panels?
Acoustic foam is a lightweight material made from polyurethane (either polyether or polyester) or extruded melamine foam. It is usually cut into tiles. One surface of these tiles often features pyramid, cone, wedge, or uneven cuboid shapes.
What is the best shape for acoustic foam?
Both Wedge and Pyramid style acoustic foam are great for the absorption of noise waves and frequencies. Although this foam will not deaden noise, both types will certainly absorb a great majority of it. Decreasing the amount of noise is determined by how many foam tiles are applied in the space, and its thickness.
Why is acoustic foam shaped like that?
Not only does acoustic foam have an obvious pattern, but the foam itself is made of many little bubbles that further spread the sound wave. The egg carton-like shape means that when the sound waves reflect, some them are likely to hit the foam, again causing them to spread out more.
