LRAD Effectively Disperses Crowds and Protects Infrastructure.
LRAD products use directionality and high acoustic output to clearly transmit critical information, instructions, and warnings well from 100 to 3000 meters. LRAD systems can also transmit powerful deterrent tones to influence behavior in hostile situations. LRAD significantly extends the standoff and perimeter in friendly or escalated environments.

The LRAD (Long Range Acoustic Device) was used for the first time in the USA in Pittsburgh during the time of G20 summit on September 24-25th, 2009

1. Like the Japanese whaling ships, and cruiseliners fighting pirates, we need one to fight the 1%
Unfortunately, I think they're the ones who own them, or their police forces do.

Wasn't there talk of one being used at Oakland or elsewhere at an OWS protest?

2. During the first attack by Oakland police, several people mentioned the use of a sonic cannon.
The LRAD can permanently damage hearing, which should be a criminal offense.

4. I was just thinking the same thinking.
I remember everyone wearing ear protection, and then ducking down when the Japanese used the LRAD.

6. Damn near took out the helo first time the Japanese aimed at it.
Eventually the SSCS developed tactics against it, primary of which is distance.

12. I have to know
You said this "Like the Japanese whaling ships, and cruiseliners fighting pirates, we need one to fight the 1%" are you suggesting that "we need one to fight the 1%" like the whalers needed one to fight Sea Shepherd in justification of their use of it?

In other words, and I want to be crystal clear here, you're equating the Japanese whaling fleet v SSCS with OWS v the 1%? Please, I urge you, be very specific in your response.

9. Since it is a directional sound wave-
Could you potentially create something to bounce it back at them? And note: this is designed to still suck even if you have ear protection

10. Parabolic reflectors would be a potential, but they'd have to be the size of a shield.
Now make a (one-arm sized) shield that is also a parabolic reflector...

New gear for protests: ear plugs plus battery-powered antisound/noise cancelling headphones.

14. No, in the video, they all back up at once. Dispersion is too wide to reflect.

11. Look up "retroreflector" --
I think these would be useful against that microwave device that produces a burning sensation as well. But you need to know what wavelength you're working with first. Sound waves may be too long for most types of retroreflector.

13. Louder than bombs! Sonic cannon used against citizenry: Pittsburgh, Tegucigalpa
Sep 26, 2009

For the first time in U.S. history, this week officials used a long range acoustic device "sonic cannon" against U.S. civilians in Pittsburgh at the G-20 protests. Meanwhile, in Honduras, the same weapon, along with chemical warfare, assaulted the Brazilian embassy sheltering deposed President Manual Zelaya.

"The police fired a sound cannon that emitted shrill beeps, causing demonstrators to cover their ears and back up," reported The New York Times. The YouTube video shows the blast deployment at the top of this post. While the link stays active at this CNN site, you can watch a CNN reporter attempting to communicate during one blast.

The UN Security Council called on the de facto government of Honduras to "cease harassing the Brazilian Embassy" and "condemned acts of intimidation" in response to sound device use and chemical warfare against the building.

The LRAD device, described as "a nonlethal weapon," is capable of emitting sound at a level that is capable of permanently damaging hearing and higher than the normal human threshold of pain (120-140 dB).
