As protests in response to the police killing of George Floyd continue to roil the country, Twitter has been abuzz lately with reports that police departments are bringing LRAD (long-range acoustic device) systems with them as part of their response.

Genasys Inc. (formerly the LRAD Corporation), which produces LRAD devices, announced in a press release Thursday that police departments in Portland, OR; San Jose, CA; Colorado Springs, CO; Phoenix, AZ; Columbus, OH; Charleston, SC; Fort Lauderdale, FL; and other cities used LRAD systems to communicate unlawful assembly and other orders to crowds after recent protests turned violent.
