More about Hearing HOW DOES SOUND OCCUR Sound is created when
the air is subjected to a disturbance – both the vibrations from
vocal cords and the pounding of a stamping machine create sound
waves. The waves are transmitted through the air and captured by
the eardrum, from which they move into the cochlea in the inner
ear, which contains hair cells with tiny cilia. The cilia move
when the sound waves reach them, and that movement is translated
into nerve impulses, which are transmitted to the brain. The
waves become sound.
