Acoustic treatment is the process to minimize the decibel level (volume) or wave interference of a sound emitted from its source with respect to a receiver. The receiver can be referred to a human, a sensitive piece of scientific equipment, or recording equipment in a studio. Acoustic treatment is given to avoid the unwanted noise. The major goals of acoustic treatment are: 1) to prevent standing waves and acoustic interference. 2) to reduce modal ringing in small rooms and lower the reverb time in larger studios, churches, and auditoriums; 3) to absorb or diffuse sound in the room to avoid ringing and flutter echoes, and improve stereo imaging; and 4) to keep sound from leaking into or out of a room..
