Question

give five practical applications of reflection of sound

Parmesh Kaur · Accepted Answer

Stethoscope, which works due to multiple reflections of
sound

Megaphone is a horn-shaped tube The sound waves are prevented
from spreading out by successive reflections and are confined to
the air in the tube

Hearing aid is a device used by the people who are hard of
hearing Here the sound waves, which are received by the hearing aid
are reflected into a narrower area leading to the ear

Curved surfaces can reflect sound waves This reflection
of sound waves is used in auditorium to spread the waves uniformly
throughout the hall Reflection of sound waves is done by using
Sound Boards The speaker is located at the focus of the sound
board
