Sound can get reflected a number of times before reaching us. The multiple of sound has a number of uses and consequences. Let us know how multiple reflection of sound is put to use by us.
1. In stethoscope, the sound of patient's heartbeat is guided along the tube of the stethoscope to the doctors ear by multiple reflections of sound.
2. Horns, musical instruments such as trumpets and sehnais, loudhailers (megaphones), loudspeakers, etc., are all design to keep sound from spreading in all directions. In these instruments, a tube followed by a conical opening reflects sound successively to guide most of the sound waves from the source in the forward direction, towards the audience. The sound waves add up and the loudness of sound increases.
3. Reflection of sound plays an important role in designing the concert halls.
