An acoustic board is a special kind of board made of sound absorbing materials. Its job is to provide sound insulation. Between two outer walls sound absorbing material is inserted and the wall is porous. Thus, when sound passes through an acoustic board, the intensity of sound is decreased. The loss of sound energy is..

What's the difference between sound absorption and soundproofing. When you realize you have a sound issue in your space, where do you start when seeking a solution? Quickly searching for soundproofing solutions may seem to make complete sense. But solving an acoustical issue isn't a one size fits all solution
When you realize you have a sound problem in your space, where do you begin to search for a solution? There are multiple ways to solve an acoustic problem: the popular, soundproofing and the less-known, but very effective, sound absorption. Knowing the difference between these two solutions will lead you to identifying..
