I cannot find the source of a constant noise & vibration that have recently (month or so) been happening in our single-family house. I've asked 2 different people, including our handyman, who checked several things, but so far only I have been able to hear/feel it.
We are hundreds of feet away from any neighbors. I've lived in several apartments and if this weren't a single-family not right next to anyone I'd be sure the noise I was hearing was either 1) a neighbor in an apartment below (only a crawlspace there) playing either an upright bass, constantly day in, day out, or music with a deep bass line.. or 2) Someone's tv on very loud at a distance, or 3) An engine of a machine of some sort with a low, constant, repetitive bass sound. Rapid Boom boom boom boom, Boom boom boom boom, over and over; I can feel the vibration in my feet or in my hand if I put it on the wall.
The house has electric baseboard heat, there is no furnace. There is a new sump pump that was installed around the time of the noise starting, cut the circuit to it off, no difference in the sound. Unplugged the fridge, no difference in the sound. I walked around the entire neighborhood trying to hear if it was coming from someone's house; nothing. The only thing we haven't tried is cutting off all electricity to the house. I guess that will be next.
It's beginning to really wear on me just as though a neighbor were playing loud music non-stop on and on and on, and I'm afraid it will begin to affect my health if it keeps up. Does anyone here have any ideas, suggestions? I hope??!!
