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!"

    Seriously, marketers will be in heaven, able to target ads at passerbys. Now you can look forward to being inundated with directed sound ads while walking the street. It'll be far more annoying because it'll be harder to ignore than ambient noise (ads running on outside speakers, people hawking their businesses on the sidewalk).

    And we think spam is bad...
