Question

How are multiple reflections of sound helpful to doctors and engineers?

Answer 1

Hint: In order to deal with this question we will understand the application of multiple reflections of sounds in real life such as stethoscopes and the ceilings of concert halls.

Complete Step-by-Step solution:
Before reaching us, sound can get reflected several times. The multiple sounds have a number of uses and impacts.
Stethoscope is a medical instrument used to listen to sounds that are produced mainly in the heart or lungs inside the body. In the stethoscope the sound of the patient's heart beat reaches the doctor's ears by multiple reflections and by amplifying sound.
Moreover, for the engineers.
The ceilings of concert halls, meeting halls, and cinema halls are built in such a manner that sound enters all the parts of the building upon contemplation. In certain halls a curved roof is arranged in such a manner that the sound travels uniformly across the hall until emanating from the roof.

Note- Sound is a sound that propagates like an acoustic wave, through a means of propagation like a gas, liquid or solid. Sound is the origin of these waves in human physiology and psychology, and their processing by the brain. If the reflection of a mirrored light ray on another object is replicated again, it is called multiple reflections. The periscopes have multiple reflections. Periscopes are found in submarines, war ships and in bunkers for troops to view things that are not clearly visible.
