I want just two things for Christmas...

[Mike Johnson]

So does #1. There've been experiments with two speakers, each projecting a beam, with highly localized sound produced where they intersect. And there's also http://www.holosonics.com/ .

we have tinkered with it at work as a non-lethal weapon. That is all i can say.

Somebody has beat your company to it, they have also demoed it of TechTV about five years ago. Same folks that make super thin flat plate speakers.

I never said when we were tinkering with it. TACOM-ARDEC was involved. But since it has been beyond 5 years, I can at least mention it....

for #1 problem, I recommend the device below. (i've even suggested this before on this forum, for what i believe God intended it to be used for - mobile phones whilst driving)

If I was asking for only two things for Christmas it would CERTAINLY NOT be those!

Whenever someone blasting obnoxious music pulls up next to me while I am driving my beetle convertible:

I turn up "Best of Tom Jones" - It's Not Unusual

or Dionne Warwick or Johnny Cash

I sing along to the music (and I can't sing)

I will take a #1.
Alternatively, something along the lines of a stun gun, that when applied to the body of the car, would fry all the electronics pertaining to the subwoofer.
