Rocks thrown to a height of 34 miles."

Interesting isn't it?

Stocker

okay but the loudest noise air can sustain is 194dB peak, 191dB RMS. So... nice chart but maybe not so much.



On a related note, being about 200 yards away from a B1-B during takeoff* will shake your chest and it's literally too loud to hear yourself think . . . or to breathe properly. That was impressive.



*four GE F101 engines on afterburner. For a long time.

Zekkal

I remember my old subs would tickle the hairs in my nose and cause some breathing vibrations... I thought I was a badass back then lol.



also was just looking up the average Train Horn Db (I'm a conductor) and came across this cool chart with a few more examples.

Is that the new v6 or the previous V8s/V10s? Because there is a distinct difference!
