Acoustic systems are sound-absorbing panels that are used in a space to control noise, eliminate slap echo, and control comb filtering. These acoustic sound absorbing panels focus on the mid and high frequencies in a space. Sound absorption is distinct from soundproofing, which is typically used to prevent sound from escaping a space.
