Question

Sometimes reflections of sound may be undesirable. Can you give an example

Answer 1

However, there are certain instances where sound reflection can be undesirable or disturbing.

One such instance is the echo of sound.

It is the reflection of sound that reaches the listener after the original sound.

Example: When two people are present in a vacant hall/auditorium and are trying to talk to each other but face difficulty due to echo of sound.
