Why is wind so loud?
In: Physics
Sound is just changing pressure waves meeting your ear. Wind is air from a higher pressure area forcing itself into lower pressure areas against the resistance of the ground and objects. This forcing obviously creates a lot of minor variations in pressure within the air itself, but also against everything that it is pushing on.
Air/wind pushing on things creates an extremely complex set of standing pressure waves as some of the air bounces off and pushes back (providing the force of the air on that thing in the first place). Those pressure waves propagate into the air as sound waves back to your ears which is why moving air creates so much sound, because there are lots and lots of pressure interactions going on at every surface and you can hear those.
