New audio tech uses ultrasound to create isolated pockets of sound, enabling private listening without headphones.

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, ...

Changing the ultrasound wave pattern led the cells to ‘dance’ into their new positions. They even created an ultrasound pattern to push cells into an ‘R’ within a gel that would hold the cells in that ...

A sound wave is a vibration that travels through a solid, liquid or gas such as the air or water. A loud sound has a large amplitude, a high pitched sound has a high frequency. Musicians and ...

Feb. 21, 2025 — Researchers have investigated how microbubbles tiny gas bubbles can deliver drugs into cells in a targeted manner using ultrasound. For the first time, they have visualized how ...

The clever bit here is that each individual wave is inaudible on its own, so nobody hears anything unless they're at the ...

DODOMA: BENJAMIN Mkapa Hospital (BMH) in Dodoma has successfully performed a groundbreaking brain surgery using sound wave ...

The global ultrasound transducer market is expected ... Innovations like burst wave lithotripsy, used for non-invasive kidney stone treatment, are also expected to drive demand.
