For hum position detection, you would want to use either geophones or accelerometers. For low frequency detection, triangulation (TDOA or time delay of arrival) will need a large separation of sensors. When they explore for oil using geophones, the source is an impulse. I don't know how well it would work with a constant humming sound.

I routinely get low frequency vibration when they are doing that midnight road work.

First of all, it's great to see you hear, Gary.
You always come up with very sensible stuff.
I still remember the Armenian shishkabob we had at the perimeters of Area 51 (I forgot what year that was).
As you may have heard already, I moved to New Mexico and now live in Rio Rancho, next to Albuquerque.
I am trying hard to locate an Armenian grocery store where I have been dying to get the shishkabob meat.

Anyway, in regards to this particular humming sound, it is my understanding that the hum still goes on 24/7.
The problem about this remote region is that it is very sparsely populated and especially at this time of the year, the weather is quite bad and accessibility if almost nil, with snow and all that.

I remember the Taos hums of the late 1980s to the early 1990s.
I even postulated my wild speculation then that perhaps Sandia Labs and Phillips Labs (at Kirtland AFB), even though they were called up to investigate the Taos hums back then, were themselves the culprits behind the Taos hums. My speculation went wild as I began to associate Sandia Labs with ELF experiments and even Sandia Labs doing some tunnel boring in that area.

Anyway, then, I began to hear the news reports in the mid 1990s that people were reporting low humming sounds near the coast of California, near such places as Lompoc and even near Vandenberg Rocket Launching Complexes. It was called the mysterious "Pacific Hum".

At this point in time, I still have no definite idea of what the hums could be.
It is still a mystery to me.

By the way, Gary, if you ever come to Albuquerque, please let me know.

The humming could also be from some kind of forcefield in the area.The aliens protecting there bases with forcefields.That could be a possibility.Oh by the way if you go looking for forcefields they will find you first.One way forcefields are a real trap.You can enter but you cannot get out.You just do not relise you have walked though a forcefield until its too late.That how they catch snooping people.They just cannot let people to return to disclose locations of secret forcefields.No wounder why so many people go missing each year.The one way forcefields does exsplain alot of things.

There are "hums" reported globally. I believe them to be related to the building of underground construction.

However, it is possible that in the case of Dulce, or any other, that it is other machinery or experimentation.

I know that these low- frequencie hums exist and have experienced one for a few years in the foothills above Boulder Colo. where I lived. The hum reminded me of a giant metallic disc on a turntable as I recall I was the only one who could hear it. As for an underground base at D.I.A Denver International Airport I will say there is nothing there but a badly done and horrifying mural that I refuse to call art. I worked at the site where D.I.A was erected since it's inception. I know of only one tunnel and the guys at P.C.L Const. that worked on it became very sick. That's about the only anomaly I know of. There is a chemical weapons depot across the street to the west of one entrance to D.I.A it's called the Rocky Mountain Arsenal there is allot of stuff underground there. Please don't tell me theres stuff under D.I.A I laid out runways and worked on the teminals and wiring the place and was there when only const. trailers were on that site. At any rate Norio I like and have followed your work and wish to thank you for your efforts. Good Day and Peace

not to sound crazy or anything, but probably like 2 and a half weeks ago. during 3 nights ( 2 nights at 12am, and one night at 1am ) all of a sudden I would hear a very low noise whose pitched changed every second. Kinda like OoOoOoO and just imagine what a UFO would sound like. Thats what it sounds to me like. Not saying it was a UFO but it only appeared on 3 occasions in a row. Also off topic, but when I try to go to sleep, I usually hear a very faint buzzing sound kinda like the annoying very high pitched mosquito sound. I made sure everything was turned off and the noise still comes. Kinda like the sound your speakers give off when your computer is off and they are on on high volume if you know what I mean. But any clues on what this noise can be?

I'm new to the site and have read some info on the "Base at Dulce" but I have a question that some might be able to answer. Like Area 51 were one can clearly see that there is at the very least something there on the surface, has someone found or know of an entrance into the facilty at Dulce? Or is there any evidence of an underground facilty large or small that can be seen? Such as vents popping up out of the ground? I have read some of the Edwin Castello interview and man if just 1% of what that guy had to say was true HOLY SH*$.

My parents still live in Dulce, I'll ask them if they've noticed anything. I haven't been out there since September, 2010 and I stood outside around 11:00pm amongst the dead silence of the reservation. Didn't hear a thing.

Also my best friends are still out there. I'll see if they've noticed anything.

I wonder if this is reminiscent of the "Toas Hum".
