[sdiy] Woah...check this out..

[Brett, Bill]

I attended a demo of one of these sound aiming devices.

They are not full bandwidth or high powered. (that is of course the stats of a couple of years ago) They do cover the critical band of human hearing, so I guess that is workable for some fun.

When one is pointed at you, you can actually feel a decent amount of air disturbance as the sound demodulates from the carrier as a result of your physical interference of the signal.

Not sure what opinion bats or other high frequency sensitive creatures think about this technology.

This was on one of the Discovery channels the other day. They were
demenstrating it's use as a VERY effective crowd control divice, then they
segued into the applications for home speaker use.

I wonder if they sound as tinny as those flat panel computer speaker
systems...
