Option 2: The persistence of sound due to repeated reflection from walls
Explanation:
Reverberation is the phenomenon in which sound continues to be heard for some time even after the sound source has ceased. This occurs due to the repeated reflection of sound waves from the walls, ceiling, and floor. When these reflected sounds merge with one another, the continuity of the sound is sustained. If the reverberation becomes excessive, the sound becomes indistinct. Therefore, sound-absorbing materials are utilized in assembly halls, cinema halls, and auditoriums.
