Question

what is reverberation of sound?​

Answer 1

The repeated reflection that results in the persistence of sound is called reverberation of sound.

Answer 2

Reverberation is the collection of reflected sounds from the surfaces in an enclosure like an auditorium. It is a desirable property of auditoriums to the extent that it helps to overcome the inverse square law dropoff of sound intensity in the enclosure. However, if it is excessive, it makes the sounds run together with loss of articulation - the sound becomes muddy, garbled. To quantitatively characterize the reverberation, the paramater called the reverberation time is used. Reverberant sound is the collection of all the reflected sounds in an auditorium.
