1. Excessive reverberation in an auditorium or big hall can blur speech intelligibility, distort music, and create an unpleasant acoustic environment by prolonging echoes, reducing clarity, and making sound muddy or indistinct.

  2. Reverberation is the persistence of sound in an enclosed space after the original sound source has stopped, caused by multiple reflections of sound waves off surfaces within the environment.

  3. The perception of multiple echoes in thunder contributes to its characteristic rumbling sound. As lightning strikes at various distances, sound waves reflect off surfaces, creating a series of delayed echoes.

  4. The rolling of thunder is caused by the dispersion of sound waves produced by lightning strikes at different distances, resulting in varying arrival times of sound waves and the perception of a continuous rumble.
