You Talking To Me

Are the “voices” talking to you again, but nobody else seems to hear them? There may be a good reason. Inventor Elwood “Woody” Norris has developed a technology called Hypersonic Sound (HSS), which can direct sound waves in a precise, laser-like beam for almost 150 meters. The result: You can be listening to music coming from across the room, but a friend standing next to you can’t hear a thing. Move a few steps outside the beam’s path, and you can’t hear a thing either.
HSS works by generating inaudible high-frequency waves that, unlike low frequency waves, don’t spread out as they travel through the air, but instead stay focused like a laser. Once this column of ultrasound reaches an object (like your head) it re-creates the original sound. Just imagine, such technology could allow ambulances to clear traffic from the streets without waking the neighbors.
