New research offering bendable sound waves that can reach only one set of ears could be the next tech revolution.

Crucially, the sound waves — specifically, ultrasound waves — used to create the audible enclaves can't be heard along the path they travel and can even be bent to avoid obstacles. Only when ...

In physics, 'ultrasound' refers to sound waves with a frequency too high for humans to hear. The sound reflects and echoes off parts of the tissue; this echo is recorded and displayed as an image ...

University of Virginia researcher Natasha D. Sheybani, PhD, has received $5.5 million from the federal Department of Defense to support her cutting-edge efforts to use focused sound waves to improve ...
