Answer
Two practical applications of the reflection of sound waves are:
- Stethoscope — It is a medical device used to hear sounds within the body mainly heartbeat. In stethoscopes the sound of the patient's heartbeat reaches the doctor's ears by multiple reflection of sound.
- Curved ceilings of concert halls — Generally the ceilings of concert halls, conference halls and cinema halls are curved so that sound after reflection reaches all corners of the hall.
