Question

Cinema theatres are designed for sound _______.

  1. Amplification
  2. Reverberation
  3. Echo
  4. Transmission

hintHint:

To reduce reverberation.

The correct answer is: Reverberation


    Reverberation means persistence of sound till it disappeared means absorbed by walls or other objects it is produced by reflection of it numerous times. So, in cinema hall theaters are designed to reduce reverberation of sound by using better sound absorbents.
