Reverberation room – Acoustic measurements to determine sound absorption
A reverberation room is a specially designed room used to measure sound absorption and reverberation time. It is used to test the acoustic properties of materials and determine accurate sound absorption values. Cellofoam has its own reverberation room where we carry out high-precision measurements to optimise the effectiveness of our soundproofing and insulation materials.
How does an reverberation room work?
A reverberation room is a sound-reflective room whose walls, ceilings and floors are highly reflective. This creates a uniform reverberation that enables the sound absorption of materials to be measured accurately. A reverberation room is used to test how much sound energy a material absorbs and how it affects the reverberation time.
- Measurement of the absorption coefficient (α) – How effectively does a material absorb sound?
- Determination of the reverberation time (T60) – How long does it take for the sound to decay by 60 dB?
- Optimisation of acoustic solutions – Development of high-performance sound absorbers
