Reverberation room for absorption measurements

Acoustic Technology has a reverberation room for sound power and absorption measurements.

Reverberation room for absorption measurementsThe reverberation room with a volume of about 240 cubic metres is primarily used for sound power measurements and for measuring sound absorption of materials.

By measuring the reverberation time versus frequency in the room both before and after a sample of the material (usually about ten square metres) has been mounted in the room, the absorption coefficient of the material may be calculated.
