Technical detail, amber alerts refer specifically to missing children. The other ones aren't amber alerts. But seemingly all of them trigger a loud sound.
Actual Amber Alerts are the ones that bother me. If I'm in my office or eating dinner, I don't want to know about a missing child last seen 20 miles away
If it was actually localized, the volume would be okay. But I live in Toronto and sometimes get amber alerts from Hamilton for parental custody disputes. That's definitely not how that system should be conducted.
