A new invention has proven that audio can successfully be transmitted directly to a listener's ears without being audible to others around.

Learn about localized audio spots, dubbed "audible enclaves," which can be placed with pinpoint accuracy while remaining ...

Ultrasonic beams fired through a 3D-printed metasurface can create localized pockets of sound that are inaudible to ...

An innovation in audio technology might make this a reality, creating personal sound zones through ultrasonic waves.

By combining ultrasound with a concept called nonlinear acoustics, you can create sound that stays silent until it reaches a ...

It may someday be possible to listen to a favorite podcast or song without disturbing the people around you, even without ...

The team tested the tech in a room with echoes to show that it can function in the actual world, such as in classrooms, cars, ...

According to the researchers, neither beam is audible by itself - it is the intersection of the beams that create a local nonlinear interaction, which generates audible sound. Furthermore, the beams ...

The researchers created localized pockets of sound, called “audible enclaves.” These enclaves are like small, invisible sound ...

Two non-linear ultrasonic waves can be used to transmit audio signals that can only be heard by a person at a very specific point.

Ultrasonic sounds are high-frequency sound waves that exceed 20,000 hertz, a range far beyond what the human ear can detect.

An innovative and non-toxic process using ultrasonic sound waves can alter the surface of glass, making it either hydrophobic ...
