USE OF SOUND IN MEDICINE
We receive the basic information around us through the organs of hearing and sight. In both cases, we receive information about objects without physical contact with them. Although sound and light are different physical phenomena, they are both waves. The energy carried by the waves stimulates our sensory mechanisms.
Sound is a mechanical wave emitted by a vibrating body. For example, when a tuning fork or human vocal chords vibrate, the air molecules around them move and change in response to the motion of the vibrating body. Oscillating molecules, in turn, transmit their motion to neighboring molecules. When the air vibrations reach the ear, they cause the drum to vibrate, which in turn causes nerve impulses that are received by the brain
