With Acoustic Innovations, Acoustic Treatment within a room is designed to work with sound to accomplish one or all of the following three things: absorption, reflection or diffusion. Absorption is used to absorb unwanted reflections from the front speakers off walls and ceilings. This often causes audible echo, frequency changes or a smearing of the movies dialog. Reflection and Diffusion elements act as reflectors to sound waves coming from speakers in the surround field. In general, Acousitc Innovations offers a fine balance of these three elements are required to pristine sound in your theater.
