It's extensively covered on the wikipedia page alone. https://en.wikipedia.org/wiki/Long-range_acoustic_device#Uni...

Also if you just google "LRAD use in [country]" there are source for any country you're actually wondering about...

If you actually read the page that you've linked, you'll see that many European countries were just using it to deliver COVID notifications

Along with offensive uses in Greece, Japan, the US, and New Zealand along with some uses on sea going vessels against pirates. It's not just notification uses and even just as a notification messages there are reports of hearing damage when turned too high.

that's not necessarely the weapon LRAD, Long Range Acoustic Devices may also be used for communication. I would be really alerted if this kind of weapon would be used in Germany.

> In the first half of 2020, Bad Homburg's fire brigade and city police used an LRAD 100X system more than 60 times to deliver COVID-19 information.

The page also lists offensive/anti-protest usages in New Zealand & USA plus a number of other places as well. For Australia the usage is somewhat ambiguous but even used just as an "announcement" it can be turned up strong enough to be painful.
