That’s what a new technology creating “audible enclaves” could one day deliver.

How do audio enclaves work?

Jia-Xin "Jay" Zhong, a postdoctoral scholar of acoustics at Penn State, used a dummy with microphones in its ears to measure the presence or absence of sound along an ultrasonic trajectory.

Audio enclaves are made using ultrasound waves, which are higher frequency than the sound waves we can hear.

Those paths converge at the destination that’s you.

This isn’t the first time we’ve been promised personalized directional audio.
