You know of one now, me. I sure don't expect my neighbors to be as quiet as church mice and when they have work to do in the woods or fields that's entirely normal. If they pass through an an ATV or snow sled, fine. Plink for a while, that's fine too. It's the moderation that counts.
I have lived in suburban areas where the constant background hum of traffic nevers quits, day and night. Ditto if living near an interstate or turnpike. The noise related to lawncare alone in suburban areas can be constant during daytime. There can also be the hydraulic whine and clanging from dumpster pickups. Then there are base speakers on stereos that can be heard for hundreds of feet easily.
I have to agree. I JUST moved from outside Detroit suburbs to rural Ohio country. I, also, have heard all these noises above, and to me that's more aggravating than the occasional train closeby. Probably the biggest bit of noise pollution at the new place is the golfers across the street, whose voices rise to make that all-elusive birdie putt (that they probably cheated on

), or the "tink" of the drive going into the very nice fishpond on #1.....
mostly aggravating because I'm sweating my @ss off mowing the grass or doing some kind of work, and they're havin fun.....
To the neighborliness part of it, I sure enjoyed assisting (appreciative) neighbors from all my past addresses, it gives a true sense of worth. I feel bad, I haven't had a chance to introduce myself to our current new neighbors, and offer any assistance....very soon!
