Atmosphere, trees, hills all seem to affect noise…I live about 600 feet from the community club and can hear the party noises often, less during the day, much during the stillness of night and much more than the neighbors closer…. The neighbors across the street hear my roosters, but next door not so much.I can hear the rooster that is a quarter mile away. Apparently so can my boys as it gets them to crowing as well. My husband says he can only hear it if it's a really good day with little traffic and that I'm just a weirdo with good ears, though. I'm not near enough anyone to care here.
