What is reverberation? How can it be reduced?


It is the Persistence of Sound due to Repeated Reflection of Sound

Reflected Sound prolongs the original sound.

Hence, Reflected sound becomes part of Original sound and we cannot distinguish between actual and original sound like in echo

Reverberation happens when time period between Original and Reflected Sound is less than 0.1 seconds.


Reverberation can be reduced by using sound absorbing materials.

For example,

Heavy curtains are used on walls

Carpets are put to absorb sound.

Seats in cinema halls are made of sound absorbing material.

Soundproofing panels are put on walls to absorb sound.
