A low hum in U.S.A., Centreville

It's a low hum that's not too loud, similar to the frequency of a diesel truck a short distance away that never stops running. The hum is quite smooth, in other words it doesn't fluctuate in tone or volume. Based on some of the other questions, you've forgotten to ask if we think we're crazy!
