Acoustic Power Measurement
What Is a Reverberation Room?
A reverberation room is a specially designed test environment that, unlike anechoic chambers, promotes sound reflections within the room.
It is used for measuring sound insulation, sound absorption, and acoustic power of test objects.
We offer both reverberation rooms and reverberation boxes tailored to your testing requirements.
We also have a proven track record with steel-structured reverberation rooms, like the example shown here.
Unlike conventional construction methods that use concrete, our reverberation rooms and boxes are built with steel structures—designed entirely from scratch to suit each customer’s measurement environment.
Steel reverberation structures offer a significantly lower cost compared to traditional concrete designs.
Below is an example of measurement data from one of our steel reverberation rooms.
We also have a proven track record in steel-structured reverberation rooms.
Our reverberation rooms and boxes are custom-designed from the ground up to meet each customer’s specific measurement environment.
