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 ...

Directing sound to a specific location is difficult because of how sound waves behave. As vibrations move through the air, ...

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 ...

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 ...

But when they intersect in space, nonlinear effects cause them to generate a new sound wave at an audible frequency that would be heard only in that specific region. Crucially, we designed ultrasonic ...

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 ...

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.

This causes the tissue to expand and contract, creating vibrations which can be picked up as ultrasonic sound waves by sensitive detectors. Different materials and molecules inside the tissue ...
