I live in an HOA (obligatory Fuck them)
They put up numerous bat boxes on poles around the common wooded area and a large retention pond right about the time Covid started.
Main reason is it’s free insect killers. We have tons of pests anyway being so close to a wooded area and a lake + the retention pond we have and the added bats help to clear some of them out.
As for the noise, no you really don’t hear them here. All the frogs are the loudest things heard of a night.
I remember as a child having more than one family member who were in their 90s. So old to me was 70s+
