Boston in 2022: 311 complaints

I live right there. It is over an amplified speaker, and probably is over 70dB at the lot line.

They don't do the calls to prayer that occur super early or super late, only the ones roughly during business hours and a bit into the evening. It's a chant that lasts a few seconds, and the text of the calls to prayer is not preachy and is objectively inoffensive (each one of the daily prayer calls is just some variation on god is good, blessed is god, etc.) unless you're someone who's offended by religion and/or brown people's very existence.

The recorded "bus to Nubian Square" announcements when the bus pulls up a couple blocks away are actually louder inside my house and occur earlier and later, as well as more frequently, and have at times woken me up and have been heard by people on the other end of my zoom calls. Again, not offensive, necessary, and normal city noise. I really see no difference between this and the mosque.

FWIW, two things can be true at the same time. There's nothing wrong with the call to prayer, but also, the city basically doesn't enforce any laws related to religious organizations. They decline to enforce noise complaints regarding churches with amplified music for hours on end, they said they wouldn't do anything about a church preaching blatantly homophobic sermons over a loudspeaker that can be heard inside people's homes because the church has freedom of speech, and they will not enforce double parking, no parking signs, or bike lane violations during the hours of nearby religious services, and they don't require any sort of permitting or traffic control so that people can safely walk and bike past houses of worship.
