What is a Reverberation Room?

A reverberation room can be considered the opposite of an anechoic chamber because its boundaries reflect, rather than absorb sound energy. 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.

The purpose of a reverberation room is to create a highly diffused acoustic measurement environment, defined as a sound field in which acoustic energy flows equally in all directions. A reverberation room must provide sound isolation against extraneous noises and an environment which can be temperature, pressure and humidity controlled. IAC Acoustics has installed many field-proven reverberation rooms in different configurations. With more than 60 years of experience, IAC Acoustics is the pioneer and leading company in the design, construction and commissioning of modular reverberation chambers.

Construction of Reverberation Rooms

For a reverberation room to perform correctly, careful consideration must be given to a number of factors which include:

  • Test Standard or Method.
  • Interior Volume.
  • Room dimensions in relation to test.
  • Interior working space.
  • Lowest frequency band of interest.
  • Internal acoustic ambient noise level
  • Noise reduction
  • Vibration isolation
  • Silenced ventilation systems
  • Doors and access
  • Lighting and electrical systems
  • Overall structural requirements
