Persistence of sound (after the source stops producing sound) due to repeated reflection is known as reverberation.
To reduce reverberations, sound must be absorbed as it reaches the walls and the ceiling of a room. Sound absorbing materials like fibreboard, rough plastic, heavy curtains, and cushioned seats can be used to reduce reverberation.
STETHESCOPE: Stethescope is a device in which the sound travels with the multiple reflection inside its column and reaches to the listeners ear.
MEGAPHONE: Meghaphone also uses the same principal so that the sound can cover a long distance.

Reverberation is frequency dependent: the length of the decay, or reverberation time, receives special consideration in the architectural design of spaces which need to have specific reverberation times to achieve optimum performance for their intended activity.
It can be reduced by using sound absorbing material.
The application of reflection is:
1. Used in megaphone
2. Used in stethoscope
