What is reverberation?
It is the sound that reflects from hard surfaces and diminishes over time. The time it takes the original level to drop by 60 dB is defined as the reverberation time.
This effect, in a church, auditorium, gymnasium, conference room, telemarketing or open office space disrupts concentration and lowers intelligibility. There may be several contributors to the problem: voices, office equipment, computer fans, heating or ventilation equipment.
Use of acoustic panels enhances the quality of the sound by reducing reflections from hard surfaces.
UltraQuiet Acoustic Cotton Panels offer an affordable, effective, and easy-to-install solution. You may install UltraQuiet Acoustic Cotton Panels on the walls, or cubicle partitions. They are Class A fire-rated, LEED (Leadership in Energy and Environmental Design) certified, safe for you and the environment.
