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

Ultrasound refers to sound waves with frequencies above the human hearing range, or above 20 kHz. These waves travel through the air like normal sound waves but are inaudible to people. Because ...

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

In a world where sound surrounds us—often uninvited and unavoidable—a team of researchers at Penn State University has ...

Twin ultrasound transducers create highly focused audio Curved sound waves aren't audible if you're not in the sweet spot Could be great in classrooms, exhibitions or vehicles Wouldn't it be great if ...

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 ...
