**CHENNAI, March 18, 2025** – Researchers have developed a technology capable of creating localized “audible enclaves,” small pockets of sound that are immune to surrounding noise, according to a study published in the *Proceedings of the National Academy of Science*. This breakthrough utilizes two high-frequency sound waves, inaudible on their own, which intersect to generate an audible sound only in the point of intersection. The technology leverages the principles of sound wave diffraction and parametric array loudspeakers, creating highly focused sound beams. Unlike traditional speakers where sound disperses, this new method allows for private conversations even in crowded environments, opening possibilities for targeted audio communication and enhanced privacy.
