Why is wind so loud?


Why is wind so loud?

In: Physics

What you perceive as ‘sound’ is actually your ear vibrating because of waves that have different frequencies.
Air just produce a wave your ear perceives

hearing is perceiving minute changes in air pressure. Wind is the movement of a shit ton of air pressure.

The ear itself is pretty much a hole with the sensory part inside the hole. when air moves over a hole, it produces different usually louder noise. This is how whistles work actually.

When a fluid (air is technically a fluid) moves at a slow speed, the molecules generally move parallel to each other. This is known as laminar flow, and results in a steady, soft sound as it blows by one’s ear.

However, at higher speeds, the molecules interact in different manners and turbulent flow is created, where the molecules start moving in more unpredictable patterns. In turbulent flow, the speed of the fluid at a point is continuously undergoing changes in both speed and direction. The irregularities in air manifest as the buffeting, irregular noise one interprets as wind.

Think of a drum, the harder you beat the drum the louder the sound produced. The sound is the vibration of air, and the bigger the impact the bigger the air vibration and the louder the sound. This air vibration causes the same air vibrations to impact on the ear drum. Therefore, if you compare the amount of air vibration caused by beating a drum, you can see how much more intense and ferocious the air movement of a strong wind can be. Also the direction of travel of these air vibrations is random and all over the place , not neat an organised like the pleasant sound of, say, music.

Wind is moving air. A *lot* of moving air. The faster it moves, the more *energy* it carries with it. When wind collides with an object, it can give that object some of its energy, causing it to move. When these objects move, they also move the air around them, creating sound. That’s the sound that wind “makes”, and the sound that you hear.

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.

It depends on your position and size of the your glutes and additional fat attached.
Think of it like a reed instrument. Open it all up and you get a “Whooosh” of wind. Close it all down and you get a “Pppprrrrttt” of wind.
With careful positioning and reliable diet you can control the noise wind makes. Start by leaning to one side when sitting – then lead to a slightly cocked leg (not too obvious!) when standing. Twerking came about as a more advanced musical form of wind manipulation – but was initially mixed incorrectly in the studio, the tracks were ruined by electronic beats. But some people persisted, not able to hear the track correctly and sadly this ended up as Staines. (Upon Thames)
