प्रश्न
What is reverberation ? What will happen if the reverberation time in a big hall is too long ?
उत्तर
The persistence of sound in a big hall due to repeated reflections from the walls, ceiling, and floor of the hall is called reverberation. If the reverberation is too long in a big hall, then the sound becomes blurred, distorted, and confusing due to overlapping and cannot be heard clearly.
