Best of What's New
The Hypersonic Sound Speakers developed by American Technology Corp. produce a pair of ultrasonic signals beyond the range of human hearing. When the two signals interact, they produce a third wave that can be heard. The effect is startling: You can't hear the audio until it strikes an object--so if the speaker is aimed at you, the sound seems to be in front of you. Target the speaker across the room and the sound will seem to originate from there--now, that's really being surrounded by sound.
