- IIAOPSW 4y agoIf the dB is high enough but the frequency is low enough, the "sound" is actually just a light breeze.
- Dylan16807 4y agoThe minimum wind speed to reach hurricane status has a pressure level of 130kg/m^2. That's 156dB. 170dB as a breeze is up around 160mph.
- IIAOPSW 4y agoSure. The sustained wind of a hurricane could be thought of as a 0 Hz 156 dB sound wave. A more ordinary passing breeze, the sort that we consciously recognize as a breeze rather than as a sound, lasts for around 1-10 seconds. So we could just as well describe an ordinary breeze as noise in the .1-1 Hz part of the spectrum somewhere above 100 dB of loudness (guessing). Alternatively, sound is just a breeze too fast for direct conscious perception.
- Dylan16807 4y agoAn atmosphere doesn't sound like a lot, but it's actually a very large amount. 0.06 atmospheres of pressure, coming from one side, is half a ton of pressure on your body.
- iancmceachern 4y ago170 dB is super high, like a shotgun blast or a jet engine close by, or a hurricane. This video goes into detail on dB ratings. It makes the point that these truck air horns that are labeled 300db on Amazon are actually many thousands of times more powerful than the Krakatoa blast, and would actually expde our planet. Spoiler, the air horn aren't actually 300 dB, they're more like 100-115. https://youtu.be/zAe9qvC49qY https://youtu.be/zAe9qvC49qY
