Question

Define multiple reflection of sound?

Answer 1

Hint: Sound is caused by the straightforward but rapid mechanical vibrations of varied elastic bodies. These when moved or struck so on vibrate, communicate an equivalent quiet vibrations to the acoustic nerve of the ear, and are then appreciated by the mind.

Complete step by step solution:
Multiple reflections of sound is that sound which is reflected quite once. During reflection, sound waves obey the laws of reflections. Sound waves have for much longer wavelength than the sunshine waves, The repeated reflection that leads to this persistence of sound is named reverberation.
Multiple reflections of sound waves are referred to as reverb, short for reverberation.
Musically it's wont to make singing and instruments sound "bigger" and "more live". Almost every pop song you'll hear today has reverb on the vocals. To experience it yourself, sing within the shower. The multiple hard surfaces close proximity create reverb.
Other uses for multiple reflections, outside of music, include things like sonar where the reflections are analyzed to make an image of unseen surfaces.
It means sound is reflected quite once. Reverberation: The repeated reflection that leads to this persistence of sound is named reverberation.

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