How do you calculate impulse response from RT60?

RT60 Calculation

The RT60 values are estimated by calculating the slope of the Schroeder curve, which is a plot of the energy (squared values) of the impulse response that is backwards integrated (summed starting from the end and moving backwards). The vertical axis of the plot is in 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.

What does RT60 mean?

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.

What is meant by reverberation time?

Reverberation time (RT) is the time required for the sound in a room to decay over a specific dynamic range, usually taken to be 60 dB, when a source is suddenly interrupted.
