Sound absorption

Describes the ability of materials to absorb sound.

When we talk about reducing reverberation within a room, we are always referring to sound absorption. In other words, the sound that is reflected from walls, ceilings and floors or from furniture is dampened and the resulting noise within the room is calmed. Sound waves are reflected almost 100% by hard surfaces such as glass, concrete, wood or metal, which are often used in construction, and therefore bounce back and forth in the room for a very long time. The noise builds up to a certain extent. Above a certain limit, which varies from person to person, the noise becomes disturbing or very disturbing.

This can only be remedied with absorbent material, such as acoustic foams, acoustic panels, acoustic blankets, acoustic curtains, etc.
