Over the past several months I have heard humming especially at night. Sometimes I think it is the beginning of a thunder roll but then realize that it is too low and continuous. It does not go away. I know that they are doing sewer work in my area but my husband cannot hear anything. It is very irritating.

It does not cause any pain but it sometimes keep me awake trying to figure out where it is coming from.

I am going to see my doctor this week and I am going to have him check my hearing and my sinus. I hope I can get some answers.

I live in South Ajax... the HUM is driving me crazy. I only hear it in this house. Not at work or anywhere else. It's a HUM that comes and goes at all times throughout the day and night. This week it has almost been constant, more than it has been in the past. There is a recylcing plant or something like that near Harwood & Bayly... could this plant be the cause of this awful HUM?

I too have experienced a low frequency hum throughout my house. It was driving me nuts. My wife couldn't hear it, only me. I traced it down to my vent stack pipes on my roof. I put a couple of 90 degree elbows on each vent to turn the outlet toward the roof. The low droning hum went away. I'm not saying that this will fix the problem that you are having but, you might give it a try.
