Remember “LRAD”? You pointed it at clumps of people in a crowd and it throws vague “energy” at them, making it so painful to remain there that they’d flee? Something radley balko would’ve shown you in 2012? It was made by American Technology Corp? https://newatlas.com/lrad-long-range-acoustic-device/11433/
Now they don’t sell “directed energy crowd control device” but “very loud relatively precise steerable speaker,” i.e. “the old thing but cranked down”.
Cf. this mild website that looks like its selling enterprise timekeeping https://genasys.com/investor-relations/
An actual “design artifact,” the very gentle Athletic Greens-colored website selling a (specifically) painfully loud speaker, as seen at end of this post in its mildest use
