Reverberation Rooms
IAC 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.
IAC Macrodyne™ 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, to assure the
overall integrity of the Macrodyne™ Reverberation Room. With the IAC Moduline® Component System, virtually any size room can be created.

Levels for Small Sources in Reverberation Rooms.
IAC has installed many
field-proven reverberations rooms in rectangular configurations. With more than
50 years experience, IAC is the pioneer and leading company in the design,
construction, and commissioning of modular reverberation rooms.
