2. Uses of multiple reflection of sound
● Megaphones Or loudhailers, horns,
musical instrument such as trumpets and
shehanais, are all designed to send sound
in a particular directions without spreading
it in all directions

4. ● In these instruments, a tube followed by a
conical opening reflects sounds successively
to guide most of the sound waves from the
source in the forward direction towards the
audience.

5. ● Stethoscope is a medical instrument useful
for listening to sound produced within the
body, mainly in the heart Or lungs.
● In stethoscope the sound of the patient’s
heartbeat reaches the doctors ears by
multiple reflection of sound.

6. STETHOSCOPE

7. ● Generally the ceiling of concert halls, conference
halls and cinema halls are curved so that sound
after reflection reaches all corners of the halls.
● Sometimes a curved sound board may be placed
behind the stage so that the sound, board
spreads evenly across the width of the hall
