i dont get how sound (a wave) can creat pressure
have you ever stood in the ocean? same principle except with air.
if you stick a tuning fork in water, the water ripples and jumps and shit. the tuning fork is pushing air around at a specific frequency. when this movement in the air happens, it pushes on our eardrums, which then shoot it through our nerves, to our brain.

a guitar string vibrates, moving air at a high frequency. the vibrations in the air are variations in air pressure. stand in front of a really loud subwoofer and you'll feel sound waves creating pressure on your body. and your ears.
