Sonora Acoustical Wall Panels, previously referred to as Respond Panels, are used to reduce echo and reverberation in applications, small and large. These panels are manufactured from a rigid high density (6-7 PCF) glass fiber acoustical board and covered with an acoustically transparent fabric. The edges on these decorative wall panels are chemically hardened and offer several choices of edge design. These absorbers are suitable for all applications including offices, recording, broadcast, worship facilities, schools, gymnasiums, museums, auditoriums, theaters or any application that requires an acoustical solution. Sonora sound panels also make a great alternative to fabric stretch wall systems. Sound control panels that look as good as they sound.
