Directed Sound

Posted by CmdrTaco on from the stay-out-of-my-sweet-spot dept.

yawningyellowyak writes "Technology Review has an interesting article on directed sound. Ultrasonic 'sound' is sent out from a 'speaker' and the distortion encountered on hitting the air produces hearable sound, but only in certain spots. You could be standing right next to someone and they would hear nothing. One step closer to the cone of silence!"

    standing right next to someone and they would hear nothing

    That would be great if someone could rig my wife up with one of these... the silence would be bliss! :)

    Sorry, it doesn't work on the noises you make.

    I saw a TV programme about this a while ago.

    One of the guys who was developing it enjoyed pointing it down towards people on the street and speaking to them. He said they got really creeped out and started looking around to see if anyone else heard it.

    I think it'd be more fun to involve two people and two speakers. Have a sort of devil and angel think going on.

    "Kill that guy over there!"
    "No, don't do it"
    "Go on, don't listen to that pussy!"

    Oh yeah, like, that's exactly what I want. Lying in bed with my girlfriend watching p0rn and then not getting laid.

    I think you might want to rethink that plan Sparky.
