Low constant rumbling vibration sound in the near distant, sometimes getting louder as it seems to be getting closer and then backs away. Sounds like Large heavy trucks slowly driving by in the near distance...if that makes sense. I�m I have always heard this sound no matter where I lived, just never really thought too much about it. It just seems louder now.
