      Hi Catherine, welcome to the forum, as you can see the hum is worldwide! can you please log your locations on Glen's hum map and you can see others close to you on the map also, it takes a min to download the map as we have 800 or so points on it.

We live up in the hills and I thought a car might actually be sitting downhill from us perhaps "casing the neighborhood". It was unsettling so I decided to get up and do a Google search for "hearing sound of distant car engine" which led me to this forum and a post from 2009 from a woman in Mtn. View, CA and another from a "hum hearer" in San Mateo.

It also turns out there was an article from 11/2005 in the local paper about a mysterious hum in Portola Valley. But no explanation was ever offered.

The rumbling sound is clearly outside my head (I've got lots of years of experience with auditory differentiation) and it is also accompanied by a physiological sensation of vibration. Much like the experience of being in a theatre while there is a loud bass sound which vibrates through the audience.
