Summary:
- Researchers have developed a technology that can direct sound waves to specific individuals in a crowded environment, allowing them to hear audio without others around them being able to hear it.
- The technology, called "acoustic beamforming," uses an array of speakers to focus sound waves and create a "sound spotlight" that only the intended listener can hear.
- This technology has potential applications in personal audio, communication systems, and even military/security uses, where directing sound to specific individuals could be beneficial.
