I'm sensitive to the low hum that some industrial tubed florescent lights give off. Not at much of a problem now as the technology has improved.
Well that idea crossed my mind, that night time work might be going on on I-696. Before today I just guessed that must explain it but now i'm not convinced. I mean how would a person even begin to investigate something oddball like a night-time vibration that does not appear to be heard outside one's home and is totally unlike an appliance noise? I also hear it in my basement because I have gone down there to check. My house is a ranch, no second story to report on.
