How the army got a patent on this I don't know - a 3400Hz tone with LFO-FM?
It's almost the same as those obnoxious car alarms. It is difficult to
screen out such a high frequency with ear protection, and ~2Hz oscillations
at volume can make some people feel ill, as such frequencies affect the
digestive organs. I assume from the shape of their projector that it seems
both very loud, and that because of an acoustical trick the bass frequency
oscillation will seem to have a great deal of power. But it's not going to
be that much use for crowd control IMHO.
I'd like to take those army guys to a drum and bass party and see how they'd
cope with those massive distorted sub basses. But perhaps that would be more
of a navy thing :-) It's clear that they know little about techno, as the
army themselves comment "TACOM's new GAYL Blaster is sure to be a
head-banger."
