New York, NY - Police Use Military Megaphone To Amplify Their Point To OWS Protesters

Photos of an LRAD being carried around by an NYPD officer were snapped by Joshua Paul.New York, NY - The NYPD’s anti-protest arsenal includes an amplifier developed for the military — but it’s being used as a loudspeaker, not a “sound cannon” to break up crowds.

It’s called a Long Range Acoustical Device and it has the ability to blast a small area with 110 decibels of sound — the equivalent of a power saw at close range.

But police officials say that’s not how it’s being used at Zuccotti Park and other protest sites, where it functions as the world’s clearest megaphone.

“We don’t use it to disrupt. We don’t use it as some horrible noisemaker,” said Police Department spokesman Paul Browne.

“We set it up away from where a crowd is. We create a 50-foot safety zone. It sends out a clear, uniform message that can be heard for several blocks.”

Theoretically, it can give a heart attack to someone with an irregular heartbeat.

THEORETICALLY, ows guys deserve heart attacks. THEORETICALLY ONLY!!!!

#1: So will climbing into an operating microwave. LRAP has a keep-out distance requirement.

Do you have the data to back up your claim? I've worked technologies much more advanced than LRAP, and have seen no such effect.

in this theory, this hypothetical person who has this hypothetical heart disease, does this person also use drugs manufactured by big pharma, and a pace maker created by big pharma, and stents created by big pharma, all traded by big bad wall street? well then as far as ows is concerned, this person should drop dead anyhow!

Well, the NYPD always abuses it's powers , and I guarantee you they will miss use this LRAD because nobody will hold them accountable !

Some common bio-effects of electromagnetic or other non-lethal weapons include effects to the human central nervous system resulting in physical pain, difficulty breathing, vertigo, nausea, disorientation, or other systemic discomfort. Interference with breathing poses the most significant, potentially lethal results. Light and repetitive visual signals can induce epileptic seizures (see Bucha effect). Vection and motion sickness can also occur. Cavitation, which affects gas nuclei in human tissue, and heating can result from exposure to ultrasound and can cause damage to tissue and organs.

Studies have found that exposure to high intensity ultrasound at frequencies from 700 kHz to 3.6 MHz can cause lung and intestinal damage in mice. Heart rate patterns following vibroacoustic stimulation has resulted in serious negative consequences such as atrial flutter and bradycardia. [9] [10]

Researchers have concluded that generating pain through the auditory system using high intensity sound resulted in a high risk of permanent hearing damage. Organizations in a research program which included the Naval Submarine Medical Research Laboratory (Groton, Connecticut), Navy Experimental Diving Unit (Panama City, Florida), SCC San Diego, Navy Medical Research and Development Command (Bethesda, Maryland), Underwater Sound Reference Detachment of Naval Undersea Warfare Center (Orlando, Florida), Applied Research Laboratories: University of Texas at Austin, Applied Physics Laboratory: University of Washington, Institute for Sensory Research: Syracuse University, Georgia Institute of Technology, Emory University, Boston University, University of Vermont, Applied Physics Laboratory, Johns Hopkins University, Jet Propulsion Laboratory, University of Rochester, University of Minnesota, University of Illinois, Loyola University,[disambiguation needed ] and the State University of New York at Buffalo, involved high intensity audible sound experiments on human subjects.[citation needed]

The extra-aural (unrelated to hearing) bioeffects on various internal organs and the central nervous system included auditory shifts, vibrotactile sensitivity change, muscle contraction, cardiovascular function change, central nervous system effects, vestibular (inner ear) effects, and chest wall/lung tissue effects. Researchers found that low frequency sonar exposure could result in significant cavitations, hypothermia, and tissue shearing. No follow on experiments were recommended. Tests performed on mice show the threshold for both lung and liver damage occurs at about 184 dB. Damage increases rapidly as intensity is increased.

Noise-induced neurologic disturbances in humans exposed to continuous low frequency tones for durations longer than 15 minutes has involved in some cases the development of immediate and long term problems affecting brain tissue. The symptoms resembled those of individuals who had suffered minor head injuries. One theory for a causal mechanism is that the prolonged sound exposure resulted in enough mechanical strain to brain tissue to induce an encephalopathy.[11]

Nice cut and paste; you sure know how to use Wikipedia. (the [citation needed] and footnote [11] gives you away). Do you really understand anything that you posted?

If you'd actually talk to the researchers and operators, as I have, you'll find that proper use of these less than lethal devices will not induce any of the "sky is falling" scenarios you so academically posted.

By the way, I can poke your eye out with my pen. Let's make pens illegal!!
