I don't know if you have it as much a we do in Britain, but do your churches have bells? Every sunday churches in Britain at 6 am, 10 am and 6 pm ring their bells for 30 mins to call their congragation into prayer/worship. Is that in your opinion on the same par or a different thing completely?
Churches here have bells, and other establishments do as well. I'm not sure if they ring around the clock everywhere, but at my college it would ring every 15 minutes. I didn't really notice it much.
If they one day replaced the bells with our school President, Graham Spainer, yelling to the entire campus to concentrate on your schoolwork, you better believe I would notice it. And yes, it would bug me.
There is a reason why they have disorderly conduct and noise violation laws here. I know first hand -- I received a citation for it.
