Excessive reverberation is undesirable in an auditorium or big hall because it can cause sound to persist and overlap, making speech and music unclear and difficult to understand.

Reverberation is the persistence of sound in a large hall or auditorium due to repeated reflections off the walls and other surfaces until the sound is reduced to a level where it is no longer audible.
The perception of multiple echoes, caused by successive reflections of sound waves, contributes to the prolonged rumbling or rolling sound characteristic of thunder.
The rolling of thunder is caused by the successive reflections of sound waves from various reflecting surfaces, such as clouds and land, resulting in multiple echoes being heard.
Echoes may be heard more than once due to successive or multiple reflections of sound waves off various reflecting surfaces, such as clouds and land.
The sensation of sound persisting in our brain for about 0.1 seconds is crucial for hearing distinct echoes because it allows us to distinguish between the original sound and its reflected echo.
The speed of sound changes with the temperature of the air. As the speed of sound increases with higher temperatures, the minimum distance required for hearing distinct echoes also increases.
The minimum distance required for hearing distinct echoes is calculated by multiplying the speed of sound by the time interval (0.1 seconds) and halving the result. For example, at a speed of 344 m/s, the minimum distance is (344 m/s) ...
To perceive a distinct echo, the time interval between the original sound and its echo must be at least 0.1 seconds.
An echo is the reflection of sound waves off an obstacle, such as a tall building or a mountain, resulting in the same sound being heard again, albeit with a slight delay.
