Audible enclaves are localized sound zones, not disturbed by surrounding noise.
They use technology to create sounds heard by only one person in a crowd.
Sound travels as waves; higher frequency means faster vibrations.
Traditional speakers spread sound waves through diffraction.
Parametric array loudspeakers focus sound into beams using modulated high-frequency waves.
Audible enclaves use two inaudible high-frequency waves.
Where these waves intersect, non-linear interactions produce an audible sound.
This creates a sound wave confined to a small area, audible only to those nearby.
This technology is different from simply focusing sound with a speaker.
