Directed acoustic energy systems represent an evolution from traditional loudspeakers to precision instruments for security applications. Modern iterations, such as the LRAD series, utilise focused sound waves for targeted communication and non-lethal deterrence across extended ranges.https://www.notebookcheck.net/From-loudspeakers-to-smart-acoustic-weapons-How-directed-sound-systems-are-engineered-today.1002000.0.html
Garbage article attempts to confabulate acoustic weapons with home audio speakers, but for what purpose? A sad inclusion for Notebook Check.
