Minnesota State Patrol uses long range acoustic device to disperse protesters (opens in new tab)

This, of course, is battery, and its use cannot discriminate between "noisy" protesters and either innocent bystanders or those who are merely exercising their constitutional right to peaceably assemble.

I guess that's better than opening fire on people with pepper balls, occasionally maiming people (including those who weren't involved in protests)?

I'd love to see a version of this for home defense though. I want to blast would-be intruders or thieves with "Sales call Abyss" or maybe baby shark.
