How do you calculate reverberation time?

Simply put, the Sabine Formula is T=0.049(V/A) where T = reverberation time or time required (for sound to decay 60 dB after source has stopped) in seconds. V = Volume of room in cubic feet. A = Total area of absorption in sabins.

What is a good reverberation time?

What is a desirable reverberation time? The optimum reverberation time for an auditorium or room of course depends upon its intended use. Around 2 seconds is desirable for a medium-sized, general purpose auditorium that is to be used for both speech and music. A classroom should be much shorter, less than a second.

What is RT60 measurement?

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.

How do you calculate reverberation time from impulse response?

It must be done by performing linear interpolation of your decay curve (or should I say Schroeder curve) with linear function: L=A⋅t+B on the correct range (which is described below). When it's done, you calculate the reverberation time from the equation.
