- alex_duf 12y agoI guess that at this level "shockwave" is more correct than "sound"
- ars 12y agoDon't forget that compression causes gas to heat up.
- marcosdumay 12y agoA 220 dB sound is quite strong. As an example, its intensity (in W/solid angle) is 14 orders of magnitude (AKA 100 billion times) highter than the 80 dB people usualy use as a safety limit.
- aruggirello 12y agoAre you sure? Shouldn't a 140 dB difference in intensity equate to just about 2^14, hence 16384 times stronger?
- jrkatz 12y agoThe decibel scale uses a log_10, not log_2.
- astrodust 12y agoSaying "quite strong" here is like saying a thermonuclear explosion is "warm". Sound that loud wouldn't just kill you, it'd rip you apart.
- abdulhaq 12y agoI think this is a US/UK English thing, in the US 'quite' only means 'very' whereas in the UK it often means 'a bit'. (I'm guessing your from the UK).
- astrodust 12y agoCanadian, which does have a lot of British influence. Saying a burrito is "quite spicy" usually means "surprisingly" but not "excessively" or "extraordinarily".
- marcosdumay 12y agoI'm Brazilian. Those things are already too subtle and hard enough to learn in a second language. People defining the same expression with widely conflicting meanings in different places do literally turn it into a maze :)
- merrua 12y agoIt should mean, you can't get it wrong, but instead it tends you mean, you are always wrong. Ah well.
- gumby 12y agoIndeed; this is the principle behind the fire piston http://en.wikipedia.org/wiki/Fire_piston http://en.wikipedia.org/wiki/Fire_piston
