Pirates thwarted with MP3 sonic blast

November 21, 2008 Somali pirates who seized a Ukrainian cargo ship return to their base in October 2008

Somali pirates who seized a Ukrainian cargo ship return to their base in October 2008. British firm 'Anti-Piracy Maritime Security Solutions' is spearheading the use of a high-tech "sonic laser" to beat pirates on the high seas. APMSS has developed an acoustic device which blast the target with a precise beam of sound which can be turned up to excruciatingly painful level.

Gone are the swashbuckling days of repelling pirates with cutlasses -- a British firm is spearheading use of a high-tech "sonic laser" to beat bandits on the high seas.

    yeah, hopefully the pirates won't make the technological leap towards ear plugs

    Ear plugs are kind of limited, I'm guessing this isn't just a loud stereo. at about 150 decibles it matters less what you have over your ears short of a soundproof room.

    Similarly high sound levels are routinely encountered and dealt with effectively during MRI procedures. Double ear plugs and sound resisting headphones do the trick quite nicely (unfortunately). I prefer the use of automatic weapons to eliminate the threat rather than discourage it and leave a residual threat which comes back another time. If the pirates see that going out gets them killed, much of the incentive to desist is lost. Lesser measures are a waste of time.

    This device is old news .. perhaps 2
    2 or more years ago a cruise ship
    used a similar thing , also with
    success, per newspaper articles.

    Its interesting that the operators
    of the device can identify the
    attackers' 'native language' from
    600 meters away .. mmmm...
    Esperanto, perhaps??

    Why don't they invest in desalination and agriculture in the region. That way, there is no need for pirating. Eliminate the source of the problem.

    Is the MP3 part just to make an interesting story? The panels I've seen have their own tones for area denial use... not that you couldn't also play music or announcements through them since they're basically special flat panel speakers.

    h1ghj3sus, do you not know how much $$ pirates make?

    I prefer the method the Indians used a few days ago. Far more effective. Once a pirates hearing is damaged/gone, LRAD probably won't be very effective. I imagine they could find men that would live with being deaf to pirate millions of dollars.

    Piracy is more profitable than agriculture. People don't always commit crimes because there is no opertinity. More often than not the dishonest professions make more cash than the honest ones.

    perhaps they are using the mp3,s that the riaa realest that have very loud but inaudible sound designed to cause hearing damage and agitation listening to those mp3,s.

    Forget LRAD... A couple RPG rounds and you wouldn't be seeing the pirates again soon. Unless you're in the shrapnel zone.

    a 50 mm machine gun might be less expensive and the noise would not be as annoying to dolphins and whales.

    It only makes them attack different ships.
    They need to be eliminated.

    They might as well have a self destruct on the ship. If they take the ship, it blows up. Take that pirates! yarrrrrrrrrrrrrrrr

    So is piracy. The Indians had it right. Sink the pirates, end of problem.

    so in the dark of night your going to wheel this contraption out, on a wavy deck. load up your music...point it, warn them...lol

    I think shooting a automatic gun roughly in their direction as a warning would probably be more effective and faster...

    Play some Yanni over that contraption. THAT'D get any self-respecting pirate an entire time-zone away!

    At 150 decibels, flac files should sound better than the best mp3 (lame @ CBR 320). I agree though ... shoot the bastards.

    From what I've seen of these weapons, it can affect your whole body, not just your ears.
    I think if loud enough, your whole body feels like it's in agony.

    A couple of problems:
    1) The range is 1000 meters. This puts the target within range of medium weight infantry weapons (much less naval) and even some light weight missiles.
    2) Sound at these levels can and do cause physical damage given long enough exposure. The first thing exposure to loud noise tends to do is make you emotionally unstable, angry in other words. If it doesn't drive you off your going to do nasty things to the people on the ship you take.
    3) If some ships using this system suffer from massacres what will other ship owners/crew do?
    4) It's a touchy-feely solution. Arming the ships with real weapons (even if international law says 'no') and increasing the patrolling of those waters will make the job less inviting to those eager for easy money.

    Hire a sniper. If you want a non-lethal solution then the sniper could take out the off-board motors. Stay ouit of range of the AK47s.
