Answer 2

1.reflection of sound: When sound travels in a given medium, it strikes the surface of another medium and bounces back in some other direction, this phenomenon is called the reflection of sound. The waves are called the incident and reflected sound waves.

2.liberation : an oscillation in the apparent aspect of a secondary body as seen from the primary object around which it revolves.

3.echo : In audio signal processing and acoustics, echo is a reflection of sound that arrives at the listener with a delay after the direct sound. The delay is directly proportional to the distance of the reflecting surface.
