Detailed Solution

The above statement is True.
A stethoscope is an instrument used by doctors for listening to sounds produced within the body, especially in the heart and lungs.
In the stethoscope, the sound produced within a patient's body is picked up by a sensitive diaphragm and then reaches the doctor's ears through multiple reflections. The sound that is reflected more than once is known as multiple reflections. Sound waves obey the laws of reflection during reflection. The repeated reflection that results in this persistence of sound is known as reverberation.
