I have tinnitus from years of working in a noisy environment. There is so much background noise living in the city of Seattle here that I don't notice much. When I go to a quiet place I really start to notice how much my ears ring. I think that noise pollution of many kinds make it difficult to sort out all the sources of stuff we hear.

Fwiw a lot of our perception of low frequency sounds is not via our ears, directly that is. The bones of our face, orbital bones etc. carry the sounds to our inner ears. This is the main reason it's harder to identify the direction low freq sounds are coming from.

Quote from upthread: "Oct 6, 2016 - 09:11pm PT
Here in southern Colorado it's either Blackhawks or troop carriers from Fort Carson or Harleys in the neighborhood. I've tried a tinfoil hat to no avail.

NO NO NO!!!!! THE TINFOIL ATTRACTS AND CONDUCTS THE MIND CONTROL WAVES BETTER. IT'S A MYTH THAT TINFOIL PROTECTS YOU PERPETRATED BY OUR OVERLORDS AND MASTERS TO BE ABLE TO BETTER CONTROL MORE SHEEPLE. DO NOT USE TINFOIL!!! IT DOESN'T REPEL THESE WAVES, IT ATTRACTS AND CONDUCTS THEM DEEPER INTO YOUR SKULL. TESLA KNEW THIS.
Sheesh, rookie.... and now, back to humjobs.

What you perceive as sound that noone else hears makes sense if you are musical. But the hum you describe sounds like the 60Hz signal of the worlds powergrid. Most people dont notice their heads resonating with EMF and RF signals that are everywhere. Musical ability is more than hearing. Musicians brains are wired to analyze oscillation. These oscillations which other peoples brains ignore, are deleted from perception. Their concious mind doesnt even get the signal. However, musical brains are wired to perceive subtle overtones and interpret harmony. It is possible that musical and other specialized brains can detect and interpret "signals" and sounds or other vibrations that most people dont even "hear." I put hear in quotes because while the signal is perceived as sound, its origin could be other. You may notice that dogs, horses and other animals can detect vibes too.

Nice, we're getting perilously close to a discussion of psycho-acoustics...
You know how if you record a meeting in a conference room, for example, when you listen back the sound has much more echo, more reverberation than you heard at the meeting? Well, the recording is much closer to the real sound, our brains process what we hear for improved intelligibility.
This applies to linguistics too. Different people around the world speak different languages and their vocalization centers on different formant frequencies. This is why an English speaking person might have difficulty understanding a Portuguese person, even if they can read and speak the language.
What this has to do with lo freq hum I don't know. I do hear the hum though if it's quiet.

Thanks, Daphne ... good article:
https://newrepublic.com/article/132128/maddening-sound
"...[trolls] Deming sees as the main problem standing in the way of understanding the Hum and other scientific anomalies. “They are inexorably attracted to anomalies of all types, but their behavior is fundamentally irrational,” he wrote in a 2007 paper. “On internet discussion forums, these people relentlessly drive out good posters and ruin everything they come into contact with. They need to be condemned swiftly and mercilessly.”

Reality is all about vibration and frequency, as pointed out by Nicola Tesla with implications and techniques long kept secret.
(Einstein was supported and promoted by the Rothschilds to obscure some of the core issues from the general scientific community.)
Light behaves as waves in 'empty' space, until bent by magnetic fields.
When the light waves are bent by magnetic fields, the interference between the bent light waves produces interference fringes between the conflicting wave patterns.
So that the nodes between interfering wave forms become what we understand to be particles of physical matter.
It seems what we perceive as the physical universe is constructed of frozen light ... analogous to a hologram.
Our minds can not directly perceive the physical universe, but depend upon our senses.
And our senses are not nearly good enough to build the internal visual world that we perceive as reality (i.e. The Matrix).
Our senses transfer electromagnetic signals along nerve bundles into our brain. These EM signals are transformed within the brain to guide the creation of our holographic world of thought that we relate to as reality.
Thus is a complex pattern of light waves that are conveyed electro-magnetically into our brains by our senses and translated into holographic realities within our minds. We relate to these holograms as if they are real ... which they are to us.
However there is no solid physical reality out there. There is light and magnetism and our perception of it as hologram patterns.

Surprising that the article didn't mention the Frey effect:
https://www.google.com/search?q=frey+microwaves+hearing&ie=utf-8&oe=utf-8
The microwave auditory effect, also known as the microwave hearing effect or the Frey effect, consists of audible clicks (or, with speech modulation, spoken words) induced by pulsed/modulated microwave frequencies. The clicks are generated directly inside the human head without the need of any receiving electronic device. The effect was first reported by persons working in the vicinity of radar transponders during World War II. During the Cold War era, the American neuroscientist Allan H. Frey studied this phenomenon and was the first to publish[1] information on the nature of the microwave auditory effect.
Pulsed microwave radiation can be heard by some workers; the irradiated personnel perceive auditory sensations of clicking or buzzing. The cause is thought to be thermoelastic expansion of portions of the auditory apparatus.[2] Competing theories explain the results of interferometric holography tests differently.[3]
In 2003–04, the WaveBand Corp. had a contract from the U.S. Navy for the design of a MAE system they called MEDUSA (Mob Excess Deterrent Using Silent Audio) intended to remotely, temporarily incapacitate personnel. The project was cancelled in 2005.[

Since 81% of Merricans are urban I aver that only 19% have any chance of hearing anything.

Jan, when I just saw the post about "Mob Excess Deterrent Using Silent Audio", well Cuba was the first thing I thought of.

Yes, just because you're paranoid, doesn't mean they aren't out to get you.

So whenever someone dismisses your concerns with "it's all in your head", well, actually they're correct.
We are all creating our reality moment by moment, and the only people who truly understand this are yogis sitting on mountain tops and perhaps a crazy physicist or two, huh?

Stanford University SLAC has a whole building full of cosmologists studying this stuff. And that's just one corner of the cosmologists community.

Alex, that is an interesting WaPo article.
However it doesn't explain the topic of this thread, for several reasons. One, it is talking about frequencies well outside human perception. Two, they are talking about relatively continuous sounds. Three, the patterns they are talking about don't vary abruptly. Four, I don't think they explain dramatically different patterns at widely separated geographical locations.
What I persist in hearing will turn on and off frequently and abruptly with no consistent pattern and often with varying frequencies.

With all due respect,how can you dismiss tinnitis? It comes and goes with me all the time.

Well, as someone who lives with serious tinnitus from having spent a year in a five inch naval gun mount I can testify it can turn on or off in an instant. Most of the time I've adapted to it and it exists in sort of a mental 'background', but every now and then it jumps to the fore and suddenly seems like a siren going off. Nine time out of ten it then just gradually fades to the back, but every now and then it just clicks off which is almost as weird as when it clicks on.
Not particularly happy stuff, but I can see how if you a mild case of it you might not necessarily recognize it for what it is.
