Lavonnie Bickerstaff of the Pittsburgh Bureau of Police uses benign language like "sound amplifiers," and "long-range acoustic device" to explain the new weapons in an attempt to sanitize what is essentially a painful weapon that leaves no visible marks on its victims. The mob utilized a similar tactic on snitches when they would beat everywhere except the face. If victims have no outward bruises to show, the world is less likely to believe their stories of assault and harassment.
Unlike aerosol hand-grenades, pepper spray, and
(Footage of the sound cannons in action can be seen/heard below. It’s clear from these videos that the extremely loud, high-pitched noise causes pain.)
The "long range acoustic device (LRAD)" is designed for long-range communication and acts as an "unmistakable warning," according to the American Technology Corporation (ATC,) which develops the instruments. "The LRAD basically is the ability to communicate clearly from 300 meters to 3 kilometers" (nearly 2 miles), said
Except, police aren’t trying to send a distress call to allies 2 miles away. They’re literally blasting this extreme decibel of noise directly into the ears of protesters (or any unwitting citizens) standing mere feet from the cannons. Depending on the mode of LRAD, it can blast a maximum sound of 145 to 151 decibels — equal to a gunshot — within a 3-foot (one meter) range, according to ATC. The
But there is a volume knob, Putnam notes, so its output can be less than max, purportedly to give us comfort in the knowledge that deafening citizens is left to the discretion of power-hungry police. On the decibel scale, an increase of 10 (say, from 70 to 80) means that a sound is 10 times more intense. Normal traffic noise can reach 85 decibels, reports MSNBC, but these sound cannons cannot be compared to standing beside a busy New York
The BBC reported in 2005 that the "shrill sound of an LRAD at its loudest sounds something like a domestic smoke alarm, ATC says, but at 150 decibels, it is the aural equivalent to standing 30m away from a roaring jet engine and can cause major hearing damage if misused."
This technology has been deployed in Iraq as an "anti-insurgent weapon," and the
Sonic weaponry is now being deployed domestically to put a chill on free speech. We’re told this is the "humane" way to deal with protesters, but it’s really just a convenient way to suppress citizens without the messy aftereffects of having to explain bullet holes to reporters. A bunch of protesters complaining about ruptured ear drums doesn’t make for dramatic news.
