A new invention has proven that audio can successfully be transmitted directly to a listener's ears without being audible to others around.
The researchers believe that these ‘whispering beams’ could be used to transmit personalized messages in public spaces, such ...
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 ...
By combining ultrasound with a concept called nonlinear acoustics, you can create sound that stays silent until it reaches a ...
An innovation in audio technology might make this a reality, creating personal sound zones through ultrasonic waves.
It may someday be possible to listen to a favorite podcast or song without disturbing the people around you, even without ...
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 team tested the tech in a room with echoes to show that it can function in the actual world, such as in classrooms, cars, ...
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.
Imagine being able to listen to your favorite podcast or song without disturbing others—without using headphones. A team of researchers at Penn State has made a breakthrough in audio engineering that ...
