Answer 1

I really have no idea.

Answer 2

it is from the generators used by the government to vent and provide energy to the underground cities they are building out your way.  

Answer 3

Low frequency sound waves - actually sensed more as vibration than sound - are tricky. They travel long distances without much damping. They can bounce off unexpected things in the ground, such as rock formations. They resonate with other large objects.

It could be caused by a freeway or a railroad or a factory miles away. It may be that these people are subject to an unfortunate geographical position or the particular construction of their house. Or they could simply be victims of the power of suggestion.  

Answer 4

it's probably distant highway traffic noise.

it's purely geographical and can only be solved with sound barriers.

Answer 5

salt mine under the house....IDK  read this before.  I live by an airport and we get strange we call UFO noise even when no plane is around !!!

Answer 6

I know there's something that causes ringing in the ears. A friend's daughter has it. She went to a lot of dr.s I don't remember what it's called.I'll google it for you. Maybe it's kind of the same thing. Only thing is...they both hear it so I don't see how it could be physical. Maybe a spirit???? IDK

EDIT....Here's a link about the ringing in the ears syndrome.

When you hear deep rumbles like this, there are actually quite a number of things that could be happening. I definitely don't think this is paranormal in nature.

It could be water rushing through pipes and "buzzing" an air bubble (which can have any frequency, high or low, depending on the pipes and the size of the bubble). I think this is the most likely, based on the comment that "it's worse in the winter".

There's also the possibility that it's constructive sound interference. This means that sound frequencies from several objects combine, and just the right combination occurs to create a new sound. In the winter, there's less grass and leaves to buffer the noise, and so it's created.

It could also be an underground printing press (yes, this sounds ridiculous, but bear me out). In some large-scale counterfeiting operations, exactly this kind of sound that appears. The fact that it disappears when city officials are called in is what makes this even appear on my list.

There are lots of other things it might be. What these people need is a directional microphone in order to zero in on its source. Once the source of the noise is found, then we can determine the next course of action.

Answer 8

Maybe it is the old man snoring or their hearing aids playing up, there's no way of guessing from that article.
