"New device puts music in your head — no headphones required"
LONDON (AP) — Imagine a world where you move around in your own personal sound bubble. You listen to your favorite tunes, play loud computer games, watch a movie or get navigation directions in your car — all without disturbing those around you.
That’s the possibility presented by “sound beaming,” a new futuristic audio technology from Noveto Systems, an Israeli company. On Friday it will debut a desktop device that beams sound directly to a listener without the need for headphones.
The company provided The Associated Press with an exclusive demo of the desktop prototype of its SoundBeamer 1.0 before its launch Friday.
The listening sensation is straight out of a sci-fi movie. The 3-D sound is so close it feels like it’s inside your ears while also in front, above and behind them...
It might work for museum tours unless they’ve figured out how to get the distortion problems fixed in the last 20 years. https://core.ac.uk/download/pdf/4393713.pdf Notice in the charts there's 10% distortion 1khz at 72db |
