Sound REINFORCEMENT system

[16.6V 10+ year member]

Hi ladies and gentlemen, I have this great idea to make military sound reinforcement system. I think Fascists experimented with something similar during WWII. The idea is that you send a sound wave of low frequency into the air and then crossover point starts to shift up so that it makes constructive interference with a lot of energy some distance away form you.

The goal is to break store windows and make pedestrians move in wave-like motion as I pass by.

I need to estimate what energy I am talking about. //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif Any help will be appreciated

What was that movie with Shaq, Steel I think, where they had that sonic gun that destroyed buildings and made a huge shockwave and all that. That movie sucked.

So yeah, just thought I would mention that. //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

you are talking about hundreds of kilowatts and massive amounts of cone area.

nothing you will be able to fit into a daily driver.

interesting idea.

And actually, the military, at least in the US, is already testing (or was testing circa 2005) a concentrated sonic weapon that is used for crowd control and deterence. I know because I was part of a mock terrorist squad and I think the 22nd Marine Expeditionary Unit was running a training guard mission on an embassy and they were using the thing on us. It was mounted on the turret of a humvee and looked like that gun from American Gladiators, with the transparent shield behind it, and you can't hear it unless it is pointed almost directly at you. It makes an extremely uncomfortable and penetrating high pitched noise that will give you a really ****ing bad headache in about 5 seconds, and it seems to bore right into your head. I have no idea what happened to the thing though.

Anyway, like I said it was mounted on a Humvee and I find it hard to believe they were using amplifiers or an electrical system beyond what was on the actual Humvee and the weapon system itself.

Dunno if that helps you or not... probably not. You might look it up though. I hope it's not classified, lol.

There are basically 2 types of sound reinforcement designs. One that is using high pitch noise, and one that is using low pitch. I want to see people moving in snake-like motion from subwoofer gun installed in the rear seat compartment and operated by another guy who can turn and aim it thorough the back windows. lol

In that case, refer to what req said. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

i am not going to use any conventional subwoofer because I need to displace great amounts of air. maybe something like this: //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

Might as well just make a rail gun while you're at it. It's basically the same thing as the diagram you posted.

I don't think that there is any feasible way for you to accomplish this. With things such as money, man power, R&D.

But hey, if you think that you can do it. Go for it

I think a good start is getting the spelling of "conductor" down. Also, a laser that melts through cars and metal would be a much cheaper and more feasable alternative. How about finding a way to use sound waves to destabilize water so it can be broken in to HHO and burned as combustable fuel without the huge amount of electricity that's needed to do the process today? You know, something that doesn't sound like a 14-16 year old with a 14-16 year old mentality wanting to build some stupid railgun for the sake of mischief?

In that diagram the piston only moves a little distance. to move the piston all the way the design should be similar to a subatomic particle accelerator - that is top and bottom magnets are actually a series of smaller magnets working in a cascade manner to accelerate the piston.

But seriously, 10kw is about 13 hp, if the piston is efficient enough, maybe you can force 1 pedestrian into a wave-like dance. But the energy of sound decreases with d^2, so if someone is going to stand 3m( 10 ft) away form the gun that person is going to be hit by 13/3^2= 1.4 hp. The question is this enough power to make a medium size woman dance a little?

And I am almost 100% sure this wont go under public disturbance.
