I know what infrasound is, binaural beats consist not only of
infrasound but audible frequencies as well as ultrasound. After
reading an article with astute, detailed information on infrasound, I
think my induced emotional drop and nausea was realistic after all.
The sound makes surrounding particles vibrate -- more times per second
with higher frequencies and shake harder with additional dBs. So, if
the volume was cranked to something like 1000 dB, your particles would
probably vibrate so violently they>d fall outta place and you>d
crumble.

No I don>t say. You can practise on Calgary if you like.

No, we do NOT perceive them as "spinning backwards,"

Actually try it and get back to us.
Actually, I have. Any number of times.
Could you elcidtae the conditions under which you

Whenever a pilot throttles up a prop-driven plane or turns the engines

Ever elcidtae that? If you haven>t then you are either blind or from

Doesn>t say they experienced 500dB-1000dB SPL though does
it!!!!!!!!!!!!!!!!!!!!!!!
(And IF it did it would be total bullshit anyway)
If they can still hear at all, it was probably less than 120-140dB SPL at
5.6 miles, and an unknown level at ground zero
