Re-address the humming house issue?
I see this discussion has been closed? Well, I'm opening it again! I have the infamous "humming house" problem now too. I've lived in this house for over 10 years and am the original owner here. Never noticed this sound until about two months ago of 2011. It was winter here in Ajax, Ontario, Canada and the "hum" started waking me up at around 4 in the morning, My first thought was, "Who would be leaving a car engine idling at this hour?". First few nights, I'd waken, irritated, and think about it, then drop off again but upon rising at 6AM the "hum" was still there. I had to conclude it wasn't a car. It sounds like it's going through a pipe or the kind of noise you hear when you make a noise through a cardboard tube. It fluctuates slightly at times but is definitely louder at night and often hardly detectable during the day. At night, I've opened windows, checked outside all doors (and at -4C it is bloody cold to have to do that!)but there's no "hum" outside. (Deceiving too because it does sound like it's coming from outside.)
I've listened to all walls in all rooms and while I can hear the "hum" all around me, it doesn't sound louder through any walls. Tried the "turning off the toilet water supply" thing - nuttin'. Tried turning off the electricity supply, and restoring it, one braker at a time and the "hum" continued throughout the whole process. I checked the water pressure into the house, turned off the water supply in fact and opened all faucets and taps to get the air out but the "hum" continued. I called in the water heater guy (who clearly thought I was crazy). No problem with the water heater. I spoke to my adjacent neighbours. They can't hear anything and neither has a ceiling fan or anything that could cause this sound through the walls. In short, I'm stumped. My next effort will be to consult the city water supplier to see if there could be a problem with the water pressure. Some nights the "hum" is so loud that believe me, anyone could hear it. There IS some truth to the fact that not everyone can hear it but still, there HAS to be some explanation! (and I don't think it's insanity or tinnitus!) It might be some kind of resonance problem but I have no idea who to consult about noise transfer like this. Yikes!

Well, thanks for your response Califdad but I've had tinnitus with ear infections and this isn't coming from my inner ear. It's not a ringing sound like that. It's a "hum" like a diesel engine. I have a two-year old fridge and the "hum" continues whether it's running or not.
Nope, no question that there is some kind of resonance from something either in the house or maybe a reverberation from some external source. As it is now, I only hear it inside. Used a screwdriver with a plastic handle, as directed from someone else online to listen to the wall- even along some of my pipes - both gas and plumbing. Heard nothing. Very weird but certainly exactly the same kind of thing as I have been reading about all over the net at this point. I have yet to find a plausible explanation. Sure hope that if people find a solution they will report it! Thanks anyway!
