Acoustic panels improve sound through sound-wave absorption. Under normal circumstances, sound released into an environment travels until it meets resistance, at which point it reflects off any surface it comes into contact with. sound bounces off harder surfaces more forcefully than it does with soft surfaces. In most businesses, churches, home theaters, garages, classrooms, conference spaces, dance halls, recital spaces, and recording studios, installing acoustical surfaces such as wall tiles and ceilings will make the biggest difference.
