Question
Cinema theatres are designed for the sound to _______.
- Amplify
- Reverberate
- Echo
- None
Hint:
To reduce the sound reverberation.
The correct answer is: None
- Reverberation means persistence of sound till it disappears means absorbed by walls or other objects.
- It is produced by reflection of sound numerous times.
- So in cinema hall, theaters are designed to reduce reverberation of sound by using better sound absorbents.
