Ok so the past several years I've noticed a humming sound when I'm in the house. It isn't anything in the house, like a fridge or tv or something; it's definitely coming from the outside. It's a low-toned hum, constant, steady, deep. I notice it most when the house is empty of people and is quiet, especially when the refrigerator is in self-defrost mode and is off. Even when the fridge is on I can still hear it. I hear it best in our family room, kitchen (both are in the back of the house), the garage (with the door closed and it's very noticeable in the car but I can still hear it if I'm standing the garage), and our bedroom and bathroom (bedroom is in the front of the house, bathroom is in the back of the house). It doesn't increase nor lessen if I open the windows, although outside noises (cars, trucks, kids playing, birds, etc) will often make me notice the hum less . . . . outside noises distract me from noticing I guess. I notice it less in other rooms of the house and don't hear it when I'm outside.
Here's the thing . . I've also noticed it's absence. It goes off or stops at times, although I can't quite get a feel for a pattern. Over the summer I didn't notice it much at all but all the windows were open if nice or the A/C was on if hot and that was enough to mask the hum. Also, the kids were home and it's just generally noisier in the house in the summer. Since I notice it's absence --- there at times when it isn't there -- it would lead me to think that it's some type of machinery or electrical pulse or . . . ? I live quite near a nuke power plant and thought that maybe it has something to do with that but I have no idea. Or could it be a noise that the earth itself is emitting? If so, what is it and why/how does it start/stop? The hubs and my oldest have also heard it so I'm not imagining it nor is it something that is just going on with my ears/hearing.
I've been looking around the internet and found this:

The Hum is a generic name for a series of phenomena involving a persistent and invasive low-frequency humming noise not audible to all people. Hums have been reported in various geographical locations. In some cases a source has been located. A Hum on the Big Island of Hawaii, typically related to volcanic action, is heard in locations dozens of miles apart. The Hum is most often described as sounding somewhat like a distant idling diesel engine. Typically, the Hum is difficult to detect with microphones, and its source and nature are hard to localize.
The Hum is sometimes prefixed with the name of a locality where the problem has been particularly publicized: e.g., the "Bristol Hum", the "Taos Hum", or the "Bondi Hum".[1]
The essential element that defines the Hum is what is perceived as a persistent low-frequency sound, often described as being comparable to that of a distant diesel engine idling, or to some similar low-pitched sound for which obvious sources (e.g., household appliances, traffic noise, etc.) have been ruled out.
Other elements seem to be significantly associated with the Hum, being reported by an important proportion of hearers, but not by all of them. Many people hear the Hum only, or much more, inside buildings as compared with outdoors. Many also perceive vibrations that can be felt through the body. Earplugs are reported as not decreasing the Hum.[2] The Hum is often perceived more intensely during the night.
Description: On 15 November 2006, Dr Tom Moir of the Massey University in Auckland, New Zealand made a recording of the Auckland Hum and has published it on the university's website.[3][4] The captured hum's power spectral density peaks at a frequency of 56 hertz.[5] In 2009, the head of audiology at Addenbrooke's Hospital in Cambridge, Dr David Baguley, said that he believed people's problems with hum were based on the physical world about one-third of the time and the other two-thirds stemmed from people focusing too keenly on innocuous background sounds.[6]
History: In Britain, the most famous example was the Bristol hum that made headlines in the late 1970s.[6] It was during the 1990s that the Hum phenomenon began to be reported in North America and to be known to the American public, when a study by the University of New Mexico and the complaints from many citizens living near the town of Taos, New Mexico, caught the attention of the media. However, in the 1970s and 1980s, a similar phenomenon had been the object of complaints from citizens, of media reports and of studies. It is difficult to tell if the Hum reported in those earlier cases and the Hum that began to be increasingly reported in North America in the 1990s should be considered identical or of different natures.[citation needed]
On June 9th, 2011, it was reported that residents of the village of Woodland, England are currently experiencing a hum that has already lasted for over two months.[7]
This phenomenon has also been reported since 2010 throughout Windsor and Essex Counties in Ontario, Canada,[8] where some residents claim it to be correlated with the time of day, or week, while others seem unaffected or unable to hear it.[9]
Explanations: In the case of Kokomo, Indiana, a city with heavy industries, the source of the hum was thought to have been traced to two sources. The first was a pair of fans in a cooling tower at the local DaimlerChrysler casting plant emitting a 36 Hz tone. The second was an air compressor intake at the Haynes International plant emitting a 10 Hz tone.[10][11]
