What is Reverberation?
This is related to the persistence of sound in an enclosed
space as a result of repeated reflections or scattering after
the source has been stopped. For example, a slow decay of
sound energy due to many reflections leads to a long
reverberation time (RT). One’s sense of well-being is affected
by the length of the reverberation time. The reverberation
time is directly related to the space volume and inversely
related to the sound absorption prevailing in the enclosed
space. The reverberation requirement is related to the
activity such as speech, music, or a recoding planned in an
enclosed space. This varies with frequency, because the RT is
inversely related to the sound absorption.
