Sound is caused by fast enough vibrations in the region of about 30 Hz to 16000 Hz.
Sound is caused due to the vibration of bodies. This would produce longitudinal percussion in the air medium. This is sensed by the human ear as sound.
Sounds are caused by the frequency, or the number of cycles per second.
Sound is caused by the vibration or the to and fro motion of a body.For example- When a hammer is struck to a metal, its surface vibrates and the air carries the sound waves into our ears and we hear the sound.
