Reverberation Time Meters

Reverberation Time is essential for describing the acoustic quality of rooms or large spaces. It is the most important parameter for describing Speech Intelligibility and the perception of music and is used to correct or normalise Sound Insulation and Sound Power measurements.


 
Reverberation Time is also useful for calculating the noise reduction in offices and factories if additional Sound Absorption materials were to be introduced.
