G20 Protesters Blasted By "Sound Cannon"

aaandre sends word of the use of a "sound cannon" on G20 protesters in Pittsburgh. Only a few hundred protesters took to the streets. The NY Times notes: "City officials said they believed it was the first time the sound cannon had been used publicly." The device projects a narrow beam of extremely annoying sound, at levels that can reach 151 decibels, over a distance of a mile or more. The Guardian notes, "It is feared the sounds emitted are loud enough to damage eardrums and even cause fatal aneurysms." Officials of the company that manufactures the sound cannon say that ear damage is only possible if someone manages to stand directly in front of the device for an extended period.

    only 150 dB? that's plenty to cause irreversable damage.

    That was a good attempt at spinning mrcaseyj's statement, but you fell short.

    You know what he was saying is that the only place the device reaches the level of 150 dB is in a one meter range.

    Not that 150 dB is a low amount.

    The evidence is in the next statement of "The sound level will drop off rapidly according to the inverse square law as you get farther away"

    But I have a suspicion that you are the type to not care about what the truth is, only how it can be twisted to fit whatever cause of the moment you are fighting for.

    Since the point of my post was to explain that it is bullshit to say "Nobody's stopping you from" immigrating/emmigrating I take it that you agree with me. Since you explain that yes, it is extremely difficult to do it (legally).

    I suppose I shouldn't have bothered to reply to/feed the trollish "Nobody's stopping you from ..." post; please excuse...
