Reverberation
The repeated reflection that results in the persistence of sound in a large hall is called reverberation.
Excessive reverberation in any auditorium/hall is not desirable because the sound becomes blurred and distorted. The reverberation can be minimised/reduced by covering the ceiling and walls with sound absorbing materials, such as, fiber-board, rough plaster, draperies, perforted cardboard sheets etc.
Practical Applications Of Multiple Reflection Of Sound
Some simple devices based on multiple reflection of sound are,
Stethoscope
Megaphone, Loudhailer, Horns
Trumpet, Shehanais
Curved ceiling of concert hall/conference hall/cinema hall
Soundboards
