Researchers have created crazy new headphone-free music tech that can beam sound waves directly into your ears.

A team of researchers at Penn State College of Engineering have been fine-tuning a technology that allows them to create ...

But a hackier way would be to build a parametric speaker that focuses soundwaves into a narrow beam like [Shane] did with this ultrasonic sound gun. As the directivity of a soundwave depends on ...

While it’s not radar, subbing in ultrasonic sensors is how [Dzl] built ... resultant echoes down in the human-audible range; they sound more like honks than pings, but it’s still pretty ...

In a nutshell Penn State researchers created “audible enclaves,” localized sound spots that only targeted listeners can hear, using intersecting ultrasonic beams that bend around obstacles like human ...

Could a multi-billion dollar industry about to go bust? That’s the road ahead if scientists can refine their promising new ...

Researchers at Penn State College of Engineering have developed localized sound zones known as audible enclaves.
