Reverberation Time

Reference data and engineering information about reverberation time for acoustics applications.

reverberationtime

Overview

Engineering reference data for Reverberation Time in acoustics.

$c = \sqrt{\gamma R T}$

Speed of sound in an ideal gas.

$L = 10 \log_{10}(I/I_0)$

Decibel level.

$\lambda = c / f$

Wavelength = speed / frequency.

The following table provides recommended reverberation times (Ta) for common types of rooms across different room volumes.
