30 days in the Sierra this summer. I kept hearing what I thought were cars or motors and just figured it was my brain used to hearing those background noises. I sat still and just WAS for many, many hours on this trip. Kept hearing motors. Hum.
Super funny at Muir Trail ranch, I woke up both mornings and just expected to see a bunch of trucks and campers when I got out of my tent. Like I was at a roadside campground. By the time my hand touched the zipper, I knew where I was and was laughing at my self. (But they did have a generator at the ranch, maybe my sub conscious heard that.)
Anytime I TRY to hear this hum, I don't, then when I DO, I think it's just my mind playing tricks on me.
No reason why it couldn't be the Earth. It's one HUGE electromagnetic generator after all!

the boring machines use liquid radioactive lithium. it cycles through the rock, melts it, and leaves a glass-lined tunnel. you guys gotta read a little more unpopular science.

@TomCochrane 9.12.12 (HUMMING NOISE POST)
Topic Author's Original Post - Sep 12, 2012 - 08:45am PT
YOUR DESRIPTION BELOW
a deep humming sound modulating slightly in frequency under load. More recently the sound is stable at one frequency, but starts and stops like a very slow Morse Code
Ok, I have just started hearing this, and it is quite accuratly decribed by you, attached above. I, as well approached this like you did, sort of scientifically via process of elimination; turning the main breaker off, stepping outside (where I usually do not hear it, similar to the majority of persons who hear this noise according to the internet), and doing rather extensive research onlinE (leading me here, one of many).
All of this started for me IRONICALLY JUST AFTER DEC 21, 2012. Which made me initally wonder if it had something to do with the planetary alignment with the center of the milky ways black hole which only takes place every 26,000 years. But apparently others have been hearing this for quite some time. And your description is the first detailed one I have found that matches exactly how I defined what I am hearing, a sort of morse code, deep subsonic (pulsing) sound with long and short lengths regarding the tones. I as well figured this was a sound eminating either from the earth itself, or possibly from space, and assuming both were natural occurances. As well I have previously saw some information on "HAARP" and pondered that as well.
Anyway, glad I have someone else who defines their unfortunate burdensome HUMM the same as mine.
Let me know if you have any additional info by email please: afj.facebook at gmail dot com .... Thank you! afj
As well check out this "IMPORTANT EVIDENCE" link, which rules out some common explanations regarding the origin of this HUMM ... once there if you click the "go back to index page" it will take you to the main site where there is much more information.
Well I will attach that "INDEX PAGE" as well:

We drove Iraqis out of bunkers with the standard North American dial tone?
According to my kid brother the Tank Commander in Gulf War I - what he used to get the Iraqis out was an armor piercing shell to blow the bunker door followed by four or five rounds of incendiaries down the open hallway.
Actually, they really didn't get out more than they got fried in place which made it easier for the SeaBees to bury them.

Is this nonsense still going on? Hey, There are no shortage of high-performance microphones and oscilloscope apps for the iPhone which can be had for under $500 bucks - put it together, turn it on, and you have a record of any environmental sound happening that isn't just in your head. If there is a real human-perceptible audio phenomena you'll have a record of it in your hand.

you need special equipment to pick up low level-low frequency sound, such equipment has been used since the early 50's for geophysical prospecting, it involves transformers made with special alloys and copper shielding that is good to 100 db and humbucking coils which adds another 45 db of noise rejection, and specially designed coils that start to roll off at about 1000 hz,
otherwise you will not be able to hear what you are after due to the s/n ratio being too low.
Triad used to make Geoformers for this application, they can sometimes be found on evilbay.

I could be wrong, but I think the hum is from the air conditioners at the Hollywood Hawaiian Hotel. At least that's what Warren Zevon told me before he died.

If you need a infrasound microphone like this to pick up the hum then you aren't hearing it as a human being:
Capacitance 18 pF
Diameter 1/2 inch
Dyn. Range 19 - 162 dB
Freq. Range 0.07 - 20000 Hz
Inherent Noise 19 dB A
Lower Limiting Frequency -3dB 0.05 Hz
Optimised Low Frequency
Polarization Ext. polarized
Polarisation Voltage 200 V
Preamplifier Included
Pressure Coefficient -0.005 dB/kPa
Sensitivity 12.5 mV/Pa
Standards IEC 61094-4 WS2P
TEDS UTID
Temperature Coefficient -0.002 dB/ºC
Temperature Range -30 - 300 ºC
Venting Side
Input Type Classic
And it jacks up the price, but still all entirely doable for an average human being if you're at all serious about looking into it. There are also plenty of DIY Geophone kits out there, but again, you aren't hearing it at those frequencies.

oscilloscope apps for the iPhone
Excuse me while I vomit.
Sure - fast digital oscilloscopes are great but using an iphone?
NOT.

NOT.
For the infrasound / geophone purposes of this thread I believe products like Oscium's would work fine.

I moved to the Santa Cruz mountain area about 8 months ago. Some time about 3 weeks ago I started hearing this humming noise and its been very annoying, it sounds exactly as you described, steady for a few moments and then pulsing and then steady and so on. I have described it to others as the sound a speaker makes when you turn the volume on a stereo up real high but no music is playing.
On whim I did a Google search and saw your post I was surprised at how your experience matches mine - I too was afraid it might be tinnitus, I still haven't ruled that out. I figure if I can record it than it's not tinnitus, but I feel like the sound is due to the locale; I work in Silicon Valley but I never hear the sound there even on quite nights.
It seems to get louder in smaller rooms - probably because slight pressure changes are more noticeable - if it is a vibration the walls and floor of the house are basically then speakers that are surrounding you on all sides. It seems like I could get a recording but I haven't tried yet.
PS I like the poster who said it might be growers - I can imagine an underground bunker with huge generators used to power the operation :)
