Question

What isreverberation? How can it be reduced?

Answer 1

Persistenceof sound (after the source stops producing sound) due to repeatedreflection is known as reverberation. As the source produces sound,it starts travelling in all directions. Once it reaches the wall of aroom, it is partly reflected back from the wall. This reflected soundreaches the other wall and again gets reflected partly. Due to this,sound can be heard even after the source has ceased to produce sound.

Toreduce reverberations, sound must be absorbed as it reaches the wallsand the ceiling of a room. Sound absorbing materials like fibreboard,rough plastic, heavy curtains, and cushioned seats can be used toreduce reverberation.
