Reverberation Rooms
Reverberation Rooms are designed for the determination of sound power output of noise sources, transmission loss of partitions, insertion loss of silencers, response characteristics of microphones, and random incidence absorption coefficients of materials. They are also used for high-intensity noise-level fatigue testing of aircraft, space vehicles, and other equipment.
Reverberation Rooms are designed not only to fully satisfy reverberation requirements, but also meet specific interior acoustic sound levels and other environmental requirements. In addition, rooms are tailored to provide suitable working spaces, sizes and types of doors, lighting and electrical systems, climate controls, as well as RF shielding appropriate to the work intended.
All these elements are assembled within an engineered modular structural framework Reverberation Room.
