reverberation time
reverberation time n (General Physics) a measure of the acoustic properties of a room, equal to the time taken for a sound to fall in intensity by 60 decibels. It is usually measured in seconds
Reverberation time
reverberation time[ri‚vər·bə′rā·shən ‚tīm] (acoustics) 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. Reverberation timeThe 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.reverberation timeA measure of reverberation in an enclosed space; the time required for sound-pressure level to decrease 60 dB after the source has stopped.MedicalSeereverberationAcronymsSeeRT |
