Related to Reverberation time: optimum reverberation time
reverberation time[ri‚vər·bə′rā·shən ‚tīm]
The time in seconds required for the average sound-energy density at a given frequency to reduce to one-millionth of its initial steady-state value after the sound source has been stopped; this corresponds to a decrease of 60 decibels.
The amount of time it takes for sound to decay 60 decibels in a given space. It is a function of room volume and amount of sound absorption provided by surface finishes in the room. Optimum levels are determined based on room volume and space usage.
A measure of reverberation in an enclosed space; the time required for sound-pressure level to decrease 60 dB after the source has stopped.
