Question

what is sound ? how is it produced and transmitted?

Answer 1

Answer:

In physics, sound is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the reception of such waves and their perception by the brain. ... Sound waves below 20 Hz are known as infrasound.

Explanation:

The sound is generated when the vibration caused by the emitter is propagated through a medium (air, water, etcetera) to end up reaching the receiver. ... This vibration is transmitted to nearby air particles that also transmit it to the adjacent particles by an oscillating movement. This is how the sound wave propagates.

Answer 2

Answer:

In physics, sound is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the reception of such waves and their perception by the brain.Sound is transmitted through the air as sound waves from the environment. The sound waves are gathered by the outer ear and sent down the ear canal to the eardrum. The sound waves cause the eardrum to vibrate, which sets the three tiny bones in the middle ear into motion.
