REPRINT FROM Feb. 5 1994: I was directed to the [compuserve newage tech] forum by several suggestions that I read up on the work of Tesla, Moray and Bearden. I have been involved in the search for the source of the "hum" since I began sensing it in April of 1992. I came across a file in Library 15 titled ELFWAR.ASC which basically describes the early events in Taos. Some of the comments were taken from the letters to the editors column of the Taos News, a weekly paper. The apparatus on Picuris peak mentioned in the ELFWAR file as being a suspect in the cause of the hum is my apparatus, or at least I am in charge of its maintenance. The apparatus is nothing more than a solar-powered commercial FM radio transmitter for KTAO. I knew that our equipment was not responsible for the hum because of several reasons. First of all, we do not operate 24 hours a day (the hum does), second, we did not begin operations until November 1991 and the hum had been reported as early as April 1991 in the Taos area. We were suspected of running a generator for supplemental power which we do not do. In the spring of 1992 I was required to snowshoe to the equipment site for some routine maintenance. I made the trek with two others who also have solar powered equipment there. I finished my tasks and while waiting for my companions to finish theirs, took out a book and relaxed behind our solar array to read. It was a very quiet day, no wind, and at 10,800 feet above sea level it can get very quiet. I could hear the ravens wings cut through the air as they circled overhead. I found myself getting frustrated because I could not seem to get past the first few paragraphs without having to begin again, something was distracting me. Then I noticed the hum. It sounded like a diesel motor idling off in the distance and at first that is what I thought it was. I focused on it and waited for it to change RPM or to get to the end of the row it was working or something but it didn't change it just kept droning on. I realized that this was what had been being discussed in our local paper's Letters to the Editors column for almost a year. The mysterious Taos hum. I mentioned it to my companions and during the trek out I kept stopping and focusing on it and it was still there. I tried to describe it to them but they claimed to "hear" nothing. To make a long story shorter, during the course of the next few months I heard the hum continuously whenever there was no ambient noise to mask it. It was in my bedroom, my bathroom, throughout the rest of the house despite my efforts to track it down. I blamed the refrigerator, the heating system fan, the VCR transformer, the flourescent light fixture in the kitchen. I disconnected the power to the house (temporarily) and the hum didn't stop. I heard t on a camping trip to an island in the middle of a lake. I talked to friends about it. Most of them laughed at me, some said I had hearing problems, others sympathized because they could "hear" it also. Since that day in April 1992, I have continued my search for the source of the "hum" and it has led me through research about ELF/VLF submarine communications, stealth detection theories and now to the New Age Science and Technology Forum. I assisted a group of scientists and technicians from various laboratories, (Sandia, Los Alamos, Phillips Air Force Lab, Univ. of NM) last May 1993 when we tried to capture the hum on tape. We were unsuccessful even though we were using rather sophisticated equipment and covered electromagnetic, magnetic, audio, geologic, and radio frequency spectrums from about 5 HZ on out to about 25 Gigahertz. We used geophones, laboratory microphones, a special "Big Ear" 15" speaker designed to be used as a microphone for low frequency sound and spent the wee hours trying to find something on our instrumentation to account for the "hum". Currently, some equipment is being developed to look at the inner ear as the source of the "hum" (to acoustic emmissions, not the same as tinnitus or meniers disease!) This project is funded by Univ. of New Mexico and will soon be looking at "hearers" ears to see how they differ from those who do not "hear" the "hum". It is suspected that even though the inner ear (or brain) may be the source of the "hum", that it is being acted upon by an external force. Something in the environment that is causing "hearers" ears or brains to (in effect) say "something is humming. I have developed a simulation of the "hum" which is created by using three sine wave signal generators. One is set at 32 HZ and the other two are set to zero beat at 64 HZ. It is almost impossible to zero beat two 64 HZ tones and the effect is a slowly undulating beat. To one of the 64 HZ tones has been added a small amount of FM modulation. This procedure is known in Great Britain by the "Hummers" (as they are called there) as "Hum matching." People who have heard the simulation claim that it is very similar to the "hum" itself. The simulation is presented at "threshold of hearing" levels during playback. At times it seems that the "hum" is being intelligently modulated. It also increases and decreases in intensity (not volume!). It seems to emanate from the pillow on my bed and during periods of high intensity it vibrates my skull and teeth. I have also been in the bathroom at 2 AM (who hasn't?) and thought someone had parked a truck outside the back door of the house and left the engine running. I've gone out to check and there is no one there and on returning to the bathroom having to go and check again because "it sure sounds like someone is out there!" I know that it is the "hum". My search has led to people all over the US, parts of Canada, and Great Britain. Letters referring to the "hum" have appeared in the Taos News from Europe as well. A common term in describing the "hum" by many of these people is the use of the word "diesel". It just seems to have that same type of signature. It also appears that musicians and those who have had musical training of some kind seem to be more likely to "hear" it and they describe it as "being out of tune" or "not supposed to be there." I am also a musician and have very acute hearing at both low and high frequency ranges (as well as midrange.) I have spoken with people in Washington state, Oregon, Utah, Connecticut, New York, Pennsylvania, Colorado, Texas, pretty much a cross section of the US who also hear the "hum". In my discussions several threads keep popping up. The work of Tesla is one of those things which has led me to the New Age libraries where I also found references to Bearden, Moray, and strange references to secret government experiments dealing with the work of Tesla. Tesla's name was frequently mentioned during the week log scientific search last May by the scientists and technicians involved. I am particularly interested in finding out more about the curl free magnetic vector potential fields alluded to in the file SCALAR.TXT in either library 8 or 15. I would like to share information with you concerning the possible uses of curl free magnetic vector fields as communications devices. I have long believed that the "hum" is a product of some form of commucications device because of the seemingly "intelligent modulation." If anyone has experienced the "hum" or has some additional information that they can share with me, please respond. END OF REPRINT ::: Hope that this brings you up to date and maybe some new information concerning the possibilities. Thanks, Sara T. Allen Date: 02-Jun-94 09:15:50 Fm: william beaty To: Sara T. Allen Do you know what kind of measurements have been done on the hum? I've always been curious about whether anyone has tried interferometry with microphones widely separated in order to do direction finding. I could imagine that it might fail by revealing the direction of sound to be from above or below. But has anyone done this? It might be as simple as: connect two microphones to the same amplifier input, place them many feet apart, listen to the amplified sound with headphones, then have someone move the microphones in a big circle until the hum is minimized. the line between the microphones will then be broadside to the direction that the "hum" travels. Oh, if you want to reply, you should probably use e-mail, since I only check in here rarely. Date: 03-Jun-94 23:11:29 Fm: william beaty To: Sara T. Allen A question: are any combinations of mics, amps, and headphones effective in amplifying the hum? If so, it's probably acoustic. If not... I'm convinced that some people can 'hear' non-acoustic energy. About five years ago a woman came into the Museum of Science to track down a noise she heard "inside" hear head there. She was suffering from loud noises in her head at home, headaches, loss of sleep, etc., and she remembered something at the M.O.S. in Boston which produced the same effect. We tried a number of devices, and the offending source turned out to be tabletop vacuumtube tesla coils, as well as large tesla plasma sphere and a plasma tube. We tried a doubleblind test, and she responded perfectly to the plasma spheres. In fact, she had to be 20' away from them or the pain/noise was too great. She described the effect as coming from inside her head, and as being different from sound. (I also read some recent research that found iron in the human sphenoid bones, and bio-iron crystals in human brain tissue. Natural radio receivers? A compass-based navigation sense?) Date: 04-Jun-94 22:21:00 Fm: Robert To: william beaty Magnetite crystals have been found in living organisms that are both magnetic (apparently used for navigation) and superparamagnetic. The latter are used to detec local variations in magnetic field. For example, certain honeybees have approx. 600 hairs descending from their bodies which are strung with superparamagnetic crystals; the magnetic domains terminate on a neuron which is also directly connected to the bee's optic nerve. These ganglion cells are thought to integrate visual with local magnetic maps. A recent report in Nature showed that a certain species of bird which can normally orient itself to the earth's magnetic field loses the ability to do so when exposed only to red light. It was proposed that rhodopsin molecules may be excited into a superparamagnetic state by sufficiently energetic photons. That is, the rhodopsin molecules may serve double duty as local field sensors. If this is true, one wonders whether a small percentage of humans may still have this sensitivity (perception of auras?). The magnetite grains found in the human brain appear to be diffusely distributed. There are many cases on record of people who could "hear" the aurora borealis, which is almost certainly an induced electromagnetic effect due to the heigth of that display (though local brush discharges may be the cause in some cases). Robert Becker has suggested that solar storms distort the geomagnetic field and that such distortions can produce psychological effects. Michael Persinger has shown that the temporal lo Date: 23-Oct-94 10:28:52 Fm: Sara T.

I'm wondering because I was aware of a number of folks, feeling a sense of urgency or emergency during that span. << Yes, there have been several intensity increases beginning with the Korean Crisis, lasting through the Haitian Crisis and especially with the recent Iraqi troop movements. Right now it is still very intense with no reported world crisis taking place. Watch the news, I expect something critical to break having to do with another outbreak of tensions within the next two weeks, perhaps related to the latest Israel bombing and their possible response to it. Me, I've just been getting monster headaches with a sense of urgency to get rid of the damn things! Of course I am aware of the real world tie in to the hum, that is, it is a man made phenomenon and really not mysterious at all, therefore I don't allow it to affect my tension level as regards to world events. I will not be manipulated that easily. Sara - Sara T. Allen, Written 23-Oct-1994 @ 10:43:03 Date: 23-Oct-94 15:16:09 Fm: william beaty To: Sara T. Allen I'm curious as to what has been tried in reducing/eliminating the hum. For instance, does the "mu-metal bucket on the head" technique do anything at all? Does the "teslar" scalar shield wristband have any effect? I recall your mentioning of tests in faraday cages and deep basements having no effect. Has there been any progress made towards getting funding for studying the phenomena? - Bill Beaty Date: 23-Oct-94 17:53:35 Fm: Sara T. Allen To: william beaty >> does the "mu-metal bucket on the head" << The last time I priced mu-metal it was really, really, really expensive. Close to $10,000 just for the material which then needs to be annealed after construction of a small box. Estimate of about $20,000 to $25,000 to try this. Regular metal grounded pot on head does nothing to stop the hum. Galvanized steel, Faraday (type) cage, does nothing to stop it. >> Does the "teslar" scalar shield wristband << I tried a friend's teslar watch with no success at stopping the hum although the ether seemed lighter to me. (not as oppressive, subjective.) >> I recall your mentioning of tests in faraday cages and deep basements having no effect. << In addition, recently, a friend descended 650 feet into a mine shaft in Michigan and noted that the hum actually seemed to increase 10 - 15% !! >> Has there been any progress made towards getting funding for studying the phenomena? << The only funding awarded to date has been Jim Kelly at the University of New Mexico for experimenting with low frequency oto-acoustic emission detection hardware and software. The initial results of the spring survey indicate that about 12% of the respondents (1,300 approx total respondents) reportedly sense the hum. I see that you are from Seattle. Do you know Buzz Towne?

Nothing showed up in electromagnetic, magnetic, geophysical, acoustic or electro static frequencies. The transducer we used to measure low frequency sound was very sensitive and didn't confirm the presence of the hum. It is theorized that it is carrier-less transmitter which is responsible. There are clusters of people who sense the hum in the midwest near the ELF site in Michigan and in Washington, and Idaho states near the ELF/VLF site there. Jet Propulsion labs recently published a paper on "Optimum Detection of Slow Frequency Hopping Signals" which provides some background on the difficulty of detecting "camouflaged" signals.

Allen >> I think that is exactly what is happening! << But does not explain why it would increase before major world events though. Unless, they would know how to get the Earth to irradiate some frequencies at some given locations. I found the info that I wanted to tell you. It's about the HAARP project. The US is going ahead with the HF Active Auroral Ionospheric Research Program (HAARP) involving USAF, US Navy's Office of Naval Research, ARCO Power to enhance C3 capabilities. The purpose is to develop high frequency ionospheric heating capabilities to: 1) generate ELF (70-150 Hz) for submarine communications. 2) geophysical probing of ionospheric processes 3) creation of ionospheric lenses for military purposes 4) ionize pathways by electron acceleration for infrared, optical and radio wave propagation in the ionosphere 5) generate new geomagnetic alignments to control reflection and scattering properties of radio waves 6) create ionospheric "mirrors" for HF/VHF/UHF surveillance of flying objects. The heating involves 1 Gigawatt (at 1 MHz to 15 MHz) from a 30 acre antenna farm in Gakona, Alaska and will operate in tandem with a Brazilian ionospheric modification program (BIME) and the Navy's RED AIR program. It is a follow up on various Soviet facilities (1 GW in Niir (Dushanbe), Sura (400 MW), Gorkiy (20 MW) and Monchegorsk (10 MW) which were by defense estimates more advanced than Western facilities in Arecibo, Puerto Rico (80 MW), Fairbanks (80 MW) and the Max Planck facility in Tromso, Norway (1 GW). It is reported that the project poses so many uncertainties that existing military bases refused to house it and many scientists consider this as unlawful and dangerous experimentation while the congress has already rejected funding in 1989 for it.

No wonder scientists are detecting gree house effects! Date: 24-Oct-94 17:44:02 Fm: william beaty To: Sara T. Allen Buzz Towne? Doesn't ring a bell. In the past I've hung out with some "weird science" types here, Dale with the giant tesla coil, Frank "Merlin" Sztazny, & Gary Hawkins with the giant capacitor bank. I was thinking about the "active shield wall" suggestion I made months ago. It might not be necessary to build an entire room-sized matrix of coils in order to cancel ELF magnetism in a small space. If humans sense the Hum with their heads and not their entire bodies, then it might be possible to wind a few 1ft. coils, run them with a negative feedback setup that cancels low-freq signals, and stick the thing on the head of a sensitive person to see if it has any effect. A similar test could be done with low frequency sound. A "sound cancellation" device will reduce the sound energy in a space around itself, and this space is a good fraction of a wavelength. Since audible sound has a wavelength on the scale of inches, sound cancellation devices are normally like headphones. But a subsonic canceller would kill the low-freq sound for several feet around itself. It wouldn't be too hard to set one up: a stereo power amp and a subwoofer speaker, some sort of filter, an a microphone with response going down to DC. The microphone might have to be built custom, maybe using a lightbeam bounced off a diaphragm, or some other position sensor connected to a diaphragm. If I knew someone locally who was sensitive to the Hum, I might be tempted to rent some equipment and try it. I DO have a 4-year old daughter, meaning that my spare time is quite limited right now! - Bill Date: 24-Oct-94 21:12:58 Fm: Sara T. Allen To: Stormdancer >> can anyone who hears it match the sound with an audo oscillator into a speaker? I hope I don't sound condecending, I just don't know what has already been tried. << The process is called "hum matching". I spent several hours putting together a simulation of what I am sensing. It requires three audio oscillators. One of them needs to be able to be modulated with a small amount of FM. Starting with a 32 Hz sine wave, add two 64 HZ sine wave into the mix and try to zero beat the two 64 HZ oscillators as closely as possible. When they are as close to zero beat as you can possibly get them add a slight amount of FM to one of the 64 HZ signals. Record it to DAT tape and play it back at threshold of hearing through a regular home stereo system and you will get an idea of what the phenomenon sounds like. Also, an audio oscillator can be used to zero beat against the phenomenon which is what I did to get the 32 HZ and 64 HZ frequencys. To get a beat frequency you need two sources. One being the phenomenom which we were unable to measure on sophisticated listening devices the other being the audio oscillator. The beat frequency is clearly detectable, but the reason why is unexplainable at this point. Sara - Sara T. Allen, Written 24-Oct-1994 @ 21:59:58 Date: 31-Oct-94 19:55:07 Fm: Sara T.

I got word this week that the Sightings episode has been expanded and will be shown sometime in November. The Encounters people are working on a segement to be aired in January which is taking the focus off of Taos and concentrating on the widespread aspect of the phenom. Our friend, James Garner, (NOT the actor), from ABQ is going to descend into a 3,000 foot mine shaft with our friend Hal, from Hancock, MI, to see if he can record the hum there. Hal reports that the hum is about 15 -20% stronger at the 650 foot level. Apparently, James has devised a method of recording the hum using piezoelectric transducers. I haven't had a chance to talk at length with him as to the particulars, however, I did hear a poor quality copy of a tape that he made, and one of the incidents recorded sounded exactly like the phenom I am hearing. I am working with a friend here in Taos to produce a one hour segment of our own which will get into the history of the hum as well as some brief technical discussions and speculations. We are planning for it to be shown on our local public access channel but are considering it for wider release if it turns out well. Sara of the Taos Hum - Sara T.

Just talked to Hal and there may be some masking problems at that depth because the ventilation system needs to be kept operating. Jim says he can filter it out. >> Can they record an amplitude, a frequency, and a modulation pattern? << So far just a demodulated sound. I really need to call Jim and get the lowdown on his methodology. Sort of been putting it off because of too many phone calls $$$$.

Allen, Written 31-Oct-1994 @ 23:15:45 Date: 01-Nov-94 19:22:21 Fm: william beaty To: Sara T. Allen > How can a human accurately sense phase? This could be done only if the Hum is audio, and so is propagating at about 1100 ft/sec, and the frequency is pretty stable. To do it, you listen to an oscillator that is adjusted to give a slow beat note, a couple times a second, have the person hit a button in time with the beat and measure the frequency difference, then move the whole setup and look for changes in the timing of the beat note. Or alternatly, you could adjust a oscillator over many minutes to maintain a cancellation of part of the Hum wave, then move the setup and see if a beat note happens in sync with the motion. What kind of motion? Well, 50 hz has a 10ft. wavelenght, so if you move at 10 ft/sec, you will hear a 1hz beat note (if the oscillator is first adjusted for zero beat.) Oops. I just realized that the short answer is: either move the human while using a reference oscillator, or use more than one human simultaneously. All this is moot if a piezo sensor can be used as a Hum microphone! Date: 01-Nov-94 19:57:39 Fm: Sara T. Allen To: william beaty >> This could be done only if the Hum is audio, << Darn, I'm fairly certain that there is no audio component to this thing. We have used very sensitive laboratory calibrated microphones and could not pick up an audio correlation to the beat frequency that the audio oscillator was producing. The night that I discovered this, Horace Poteet of Sandia National Lab and I were sitting in the equipment van armed with a vast array of sensing equipment. Both he and I were sure that we were going to capture the hum on tape. After hours of monitoring and watching our screens and adjusting and making measurement after measurement we looked at each other and agreed that the "hum" is not an acoustic phenomenon. Both he and I can sense the hum in the environment so we knew that it was present at the site of the attempted measurements. I haven't yet had confirmation on the piezo transducer. One thing that I can say about the hum though is that it's intensity doesn't vary from place to place in a given area like North Central New Mexico. If it is at a particular intensity at my home it will be at that same intensity at my transmitter site or at the lake or across town or across the county. The intensity does vary from time to time however. It was down in intensity for awhile on Saturday and I thought we might get a few days of relative quiet but Sunday Morning it was at high intensity again and has remained so through this evening. Thanks for your suggestions. Keep making them, something might just click. Sara - Sara T. Allen, Written 01-Nov-1994 @ 20:54:57 Date: 02-Nov-94 15:49:37 Fm: william beaty To: Sara T. Allen Is it an impossible task to zero-beat the several hum frequencies and at least temporarily cancel the hum via headphones? I realize that the oscillators would drift in phase relationship to the hum unless they could be somehow dynamically adjusted. Doing all this might not be valuable for anything, but since an audio signal DOES beat with the perceived HUM, the implication is that the "sound" of the hum can be cancelled with a perfectly- adjusted set of audio oscillators. Might be neat to try. Too bad that the hum is not acoustic. The wavelength of 60HZ EM is a bit longer than tens of feet!! - Bill B. Date: 02-Nov-94 19:46:51 Fm: Sara T.

Allen To: All OK, Here is the skinney on the piezo electric device transducer developed by James Garner in Albuquerque. After cracking open an over the counter piezo electric high frequency speaker and removing the piezo device and soldering it perpendicular to a copper clad circuit board, sort of like a Pressure Zone microphone, and adding a square coil of wire to the top of the piezo device, then taking the output of the piezo and applying it to a 2 stage high gain darlington circuit and using passive r/c networks to filter out unwanted stuff, the output was applied directly to another series of high gain discrete transistor amps with each transistor hand balanced with bias at mid point, he was able to record the result to tape. It is not a perfect reproduction but close enough for me to recognize it as the (Taos Hum) phenomenom. Unfortunately, during a demonstration for 60 minutes ( I wasn't aware that they had made a 60 minutes segment on the hum, but I don't know everything,) a year or so ago, his very old o'scope passed the smoke test and made smoke thereby applying high voltage to his circuitry destroying it as well. All that remains is a tape recording of the output and a video tape (which CBS has) of the o'scope presentation along with the hum. He doesn't have schematics :( but gave a very good description of the circuitry, keep it simple. He spent the entire month of December 1992 (I think) balancing each transistor. He used 2N2222 general purpose transistors with 2 in the preamp, and 15 in the secondary. At one point he described a feed back loop he set up by applying the output of the piezo to the circuit and then to his hi-fi speakers and caused what he said was a fascinating display of rumbling and shaking of his neighborhood and calls from his neighbors asking what the heck he was doing. Reminded me of the Tesla building shaking device description. The piezo device is interesting. Anyone know exactly the composition of a piezo transducer? He said it is a piece of metallized plastic that when stretched outputs a voltage, (reminded me of some of the stuff Brazel found in Roswell.) (How would that work for UFO propulsion, an entire craft made up of a flexible, variable crystalline matrix.) My understanding is that the transducer has a crystalline matrix structure which when vibrated by audio wave forms produces a sound and vice versa, when stimulated by a sound, produces a voltage. I don't know if or when I will get the time to construct such a device, but I have all winter to draw up the schematics and do some breadboarding of my own. I wonder if a balanced op amp instrumentation circuit to cut down on common mode signals instead of the discrete device would be an improvement. Along with selectable, adjustable, low pass, high pass and bandpass circuitry it just may do the trick. Right up my alley. James said that he recommends using the passive filtering over active filtering. He is going to try to rebuild his circuit also and has given me his cooperation in developing my own here. More later, I'm hungry. Sara - Sara T. Allen, Written 02-Nov-1994 @ 20:40:38 Date: 08-Nov-94 17:32:52 Fm: Sara T.

His track record to date on this is in March of 1993 he came out and said "Yes it is the military that is causing it." Then the DOD denied it and Bill relaxed his stance. Then I wrote him a letter in which he claimed to believe that the hum was real and that it is "imperative" that the source be found and stopped. When the contents of the letter were brought up to him on Saturday he said that he didn't think his constituency was interested in this issue, that he believed it to be a natural phenomenon, and that he didn't believe that anyone was suffering from it. After the interview I pointed out that the hum is widespread and that I am in touch with people nationwide who claim to be having adverse health effects, etc. etc. etc. He said he would once again have his intelligence committee look into it.

But humans can be 'used ' as transducers to make objective measurements if the humans can report the cadence of the beat between the Hum and an audio oscillator. For example, if the Hum frequency is fairly stable, then the audio oscillator can be varied, and the human will respond by tapping out a rhythm that varies in frequency and phase with changes in the oscillator freq., and several isolated human listeners hearing a beat note from the same oscillator will tap out the same rhythem, and all of them will follow changes in the oscillator. Of course this might not work if the Hum frequency drifts around, or if the beat note is so weak that the human listeners have trouble reporting its rhythem. This would be a fun experiment to perform, but if a physical transducer is discovered, there wouldn't be much point. - Bill B. Date: 09-Nov-94 06:15:02 Fm: Sara T. Allen To: Rick >> there would be some trouble still in detecting those low frequency acoustic waves which would probably be very low power too. << They are very low power emanations from the ear, if they exist at all, which is the stated goal of the experiment being carried out by Jim Kelly at UNM. The last I heard was that they had gotten the equipment to -20 dbspl using noise cancellation circuits, that is quite impressive but still not enough. I know that there is a piece of equipment that will detect and record this signal, it just happens to be classified. I have recently gotten some corroboration from Gov. Svc. people that such a thing exists, that it is operational, that it is being used for worldwide sub com, that it is probably operating in the 7 hz region (alpha wave alert!), and that LANL is assisting in some way. Also, that the fact that some people are sensitive to it and can act as detectors is a side effect that was unforeseen and they don't know what to do about it. I should be hearing today if I am off to Seattle for the weekend ABC affiliate interview. It sounds like it could be a fun trip to meet some of the people that I only know from C-space in 3d.
