Three years ago Congress directed scientists and observers from some of the most
prestigious research institutes in the nation to look into a strange low frequency noise
heard by residents in and around the small town of Taos, New Mexico. For years those who
had heard the noise, often described by them as a "hum", had been looking for
answers. No one was sure when it began, but its persistence led first a few and then many
of those who heard it (called "hearers" by each other) to band together. In 1993
they found their way to Congress.
The investigation Congress requested consisted of a team of a dozen investigators from
a number of scientific institutions. Joe Mullins of the University of New Mexico and
Horace Poteet of Sandia National Laboratories wrote the team's final report. Other New
Mexico research organizations involved included Phillips Air Force Laboratory and the Los
Alamos National Laboratory. Concern by hearers that the hum might have been caused by the
Department of Defense ensured that the investigation was conducted in the open and that a
large number of persons were contacted.
The first goal of the investigative team was to interview hearers and try to determine
the nature of the hum the sound it made, its frequency, timing and its effects on those
who heard it. Next the team planned to survey residents of Taos and the surrounding
communities to determine how wide spread the hum was. Finally, the team was to try to
isolate and determine the cause of the hum. Important to their effort was the team's clear
interest in deter-mining the cause of the phenomenon, rather than questioning the hum's
existence. There was a generally clear understanding by the investigators that something
was happening here, but just exactly what it was seemed to defy definition.
The initial investigation focused on ten hearers and determined certain key facts
surrounding the hum. It was persistent. It was heard by only a small number of people. The
sound was extremely low on the frequency scale between 30 and 80Hz. There was variation
in how different hearers perceived the sound. Some heard a sound like the low rumbling of
a truck while others heard a more steady, pulsing, yet still low sound. Interestingly, the
investigators learned that the sound was not limited to the area around Taos, but was, in
fact, heard at places all over the country and around the globe.
Hearers described the increasing problems they were having with the hum. Consistent
with the reports and complaints that had brought the issue to Congress in the first place,
hearers described the hum as a cause not just of annoyance, but also of dizziness,
insomnia or sleep disturbance, pressure on the ears, headaches and even nosebleeds. The
hearers were also bothered by the disturbing nature of its existence: it did not seem like
a natural phenomenon to them. According to the August 23, 1993 " Taos Hum
Investigation: Informal Report", most hearers initially experienced the hum with an
"abrupt beginning, as if some device were switched on." Many of the hearers
believed there was a connection between the hum, the military installations in and around
New Mexico, and the Department of Defense or that the hum was somehow caused by the U. S.
Navy's ELF (Extremely Low Frequency) stations in Northern Michigan. These suspicions made
a civilian presence on the investigation team necessary.
After examining ten hearers the team (now including James Kelly, a hearing research
scientist with the University of New Mexico's Health Sciences Center) began a broad survey
of Taos locals. Their survey of 1,440 residents led the team to extrapolate that roughly
2% of the Taos population were hearers.
Given this large number of hearers, initial exploration of a source for the hum focused
on external possibilities for generation of the low frequency hum. While there were
isolated instances of hearing within the low frequency range identified by hearers, these
tests revealed no consistent background noise which could account for the hum. As Mullins
and Kelly concluded, there were "no known acoustic signals that might account for the
hum, nor are there any seismic events that might explain it."
Having ruled out external sources the team focused on testing hearers' inner ears and
on researching frequency sensitivity. While these investigations are not complete, it
appears highly unlikely that the hum is caused by low frequency tinnitus as some have
speculated. Mullins and Kelly are more inclined to believe that hearers have developed a
specific sensitivity to sounds in the 20 to 100Hz range and therefore are directing their
research toward gleaning an understanding of how the ear perceives low frequency energy.
While this approach may help answer the persistent question of the hum's origin, Dr.
Nick Begich and Patrick Flanagan (a Sedona-based inventor and scientist), have explored
another possibility. Dr. Nick Begich has found some interesting clues in Mullins' own
comments that might lead to another source for the hearers' unique ability and, perhaps in
the long term, a solution to their near-debilitating problem.
To support the future direction of his research Mullins has pointed out that, as a
nation, "...we're slowly building up the background of electronic noise...We're going
to more and more cordless things all electromagnetic transmitters. Whether that's the
cause of the hum, we don't know, but we can't write it off."
Begich theorizes that the cause of the hum may be found within this electromagnetic
background buildup. He believes that there is a mechanism for the transduction of sound
which might explain the hum. The key may be hidden in a technology invented by Dr. Patrick
Flanagan. NeurophonicTM sound technologies were developed based on an understanding of
sound transfer using different "hearing" pathways to the brain. Standard sound
measuring and diagnostic equipment would be ineffective in locating the "sound"
Patrick Flanagan's NeurophoneTM, invented when Flanagan was 14, is a low voltage, high
frequency, amplitude modulated radio oscillator. In simpler terms, the NeurophoneTM acts
on the skin of the listener by converting "...modulated radio waves into a neural
modulated signal that bypasses the 8th cranial hearing nerve and transmits intelligence
directly into the learning centers of the brain." In other words the NeurophoneTM
allows the listener to "hear" without having to use the ear canal or the bones
and nerves we normally associate with hearing.
Flanagan's patent was approved after a six year fight with the patent office
culminating in a test of the device on a hearing impaired patent office employee. The
demonstration convinced the patent examiner that the NeurophoneTM worked, even though it
appeared to fly in the face of traditional concepts of how we hear. The novel concept with
the NeurophoneTM is that we use the skin itself as the neural transmitter.
This concept is actually quite simple. When in the womb, a fetus's skin serves as the
primary sensory organ. From it evolve the eyes, the nose and the ears. While the ears
specialize in hearing, Flanagan recognized that the skin is also an organ. Consequently,
if a way could be found to transmit information through the skin to the brain, then
information could be directly communicated to the brain, bypassing the ears. The
NeurophoneTM ran radio waves through two small electrodes placed on the skin and
essentially used existing neural pathways to directly access the brain.
Flanagan's NeurophoneTM research offers a possible explanation for the Taos hum. As
Mullins has pointed out, we are surrounded by a large number of low frequency devices
devices all operating around 60Hz. Given Flanagan's NeurophoneTM concept, it is possible
that this concentration of frequency may well be resonating with the skin causing a direct
neural link between the skin and the brain. As with the NeurophoneTM, some individuals are
more receptive than others. Consequently, some persons' skin could be more receptive to
ambient electromagnetic frequencies than others.
Flanagan and Begich speculate that the NeurophoneTM could be pulsed at the frequencies
identified by those hearers interviewed by Mullins and the investigative team. If the hum
was generated by ambient electromagnetic fields then the NeurophoneTM technology could be
used to mitigate it. While Mullins is investigating the ear canal and our human hearing
apparatus, Flanagan and Begich believe that the answer is more likely to be found through
the pathways established by the NeurophoneTM, which bypass the ear entirely.
Proof of whether or not their theory is correct is reliant upon testing of hearers. If
Begich and Flanagan are correct, the NeurophonicTM technology and what has been learned
about hearing may well be used to alleviate the suffering of hearers as the search for the
source of the hum continues.
