Hyper Sonic Sound, HSS, are uber cool directional speakers invented by Woody Norris. What are they, well, basically, if I stuck a flashlight in front of the speaker, only people within the lights cone would be able to hear what I was broadcasting. It’s the strangest feeling. First you hear it, then you dont . The other wow factor is you cant tell which direction the sound is coming from. I don’t quite understand how it works, but I’ve had the chance to play with and have never seen or heard anything like it. When someone points the speaker at you, it sounds like there’s a speaker inside of you, playing through your lungs or sum something. It’s mad weird!!!!! but uber cooool!
There’s another invention like it called the audiospotlight done by a MIT graduate. Anyhow, I’m not sure what the future of sound is, but this is for sure one revolutionary step for it.Hyper Sonic Speakers
