Not as load as some would think
I live in the middle of a residential subdivision on 1/4 acre lots about 200 yards from a heavy use secondary road and 1 mile from a Fire House.
Except for the odd weekend one of the neighbors is having a party the back yards are very quiet except for the occasional dog.
You can hear the larger vehicles out on the main road and the emergency truck's sirens. Around 3:00AMish you can hear the trash trucks banging the dumpsters 2 miles off to the east and around 5:00AM you can hear the train down by the river 2 1/2 miles away.
You have to really listen to hear the far off sounds and I've hear the same while up in Uwharrie.
