How do you measure reverberation time in a room?

Create a stable sound field using a sound source. Start a sound measurement instrument, such as a sound level meter. Switch off the sound source and allow the sound to decay. Wait for the background sound to stabilize and stop the measurement.

What is used to measure reverberation?

Reverberation Time can be measured using either Impulsive Excitation (Schroeder method), such as from a pistol or balloon burst or by using Interrupted Noise, with the built-in noise generator.

What is the most optimal reverberation time?

For average control room volumes, preferred reverberation times fall into the 0.3 to 0.4 second range. In recording studios the reverberation times are variable, and range between 0.8 and 1.5 seconds, depending on the size of the room.

Which type of acoustical measurement indicates the reverb decay time for a room?

We use the metric Reverberation Time 60 (RT60). RT60 is defined as the measure of the time after the sound source ceases that it takes for the sound pressure level to reduce by 60 dB.
