Q. What is the resonance of sound? What measures should be taken to stop resonance?
Resonance of sound
When sound is heard in an empty hall or a large room, the sound is reflected repeatedly from the walls, floor or ceiling of the room, creating a humming sound. This sound is heard for a while after the original sound has stopped. This is called sound resonance.
What measures should be taken to stop the sound resonance?
Sound absorption in the room is reduced by having sound-absorbing materials on the furniture and walls. Even with a crowded audience, resonance is reduced, as the listener’s body and clothing absorb the sound.
