I live on Hemlock Lane, not too far from Soccer City, and there has been a very annoying, low-pitched, and long-lasting (1-2 hrs+) humming/rumbling sound in the neighborhood for many nights. This has been going on for at least a couple of weeks, and is fact the reason I created an account on this site! It sounds like it's coming from everywhere, if that makes any sense - very difficult to localize. I can't for the life of me find out where it's coming from, other than generically "outside", but it is extremely irritating and is ruining my sleep. It usually happens around midnight, but on occasion it has kept me up until around 3AM. Does anyone else in the area hear this? If so, do you know where it might be coming from and what can be done about it?
