Mobbing close to the bone: Bone conduction

The technique of bone conduction, a method of transmitting sound waves to the inner ear through bone, is a close-range technique of harassment. It is the chief method, perhaps, used to convey harassment to me whenever I put my ear to the pillow, no matter the thickness of the sound board I use against my window panes. Instead of being a technology, bone conduction is criminals making the most of the anatomy of the human ear.

Not knowing what this phenomenon was called, but having experimented with blocking it with earplugs or by changing body position or the closeness of my ear to the pillow, I figured that a doctor could explain it to me based on his training in human anatomy. But then I came across the term bone conduction.

The use of bone conduction is another indicator of the possible involvement of those with some level of medical training in my mobbing. After all, the mobbing has included references to my health, my medical records and, from time to time, has softened based on the mobbers’ observations of some physiological reaction induced in me by the stress of the mob. It made sense to me, that if there is money involved in mobbing, if those who do it are practiced professionals who “safely” remove residents from properties they or those who hired them want to acquire, they would be attentive to the health of their victims, if for no reason other than liability. And given the fact that the mobbers have used other physical vulnerabilities in the harassment, for example, allergies or fatigue, their willingness to take advantage of my very bones to harass me from close range in a manner that I could not escape was par for the course.

Judging from the copious references to “voice-to-skull” (V2K) harassment on sites where real estate mobbing may be miscast as government conspiracy, the technique of harassment by bone conduction figures prominently in a lot of criminal property acquisition.

Bone conduction includes compressional and inertial bone conduction. Compressional bone conduction is the individual vibration of segments of the skull. This type of vibration compresses the bone in the inner ear and allows for the perception of sound. Compressional bone conduction is the result of high-pitched sound. Inertial bone conduction vibrates the entire skull while the sound sensing parts of the inner ear remain at rest. This type of bone conduction results from sounds of low pitch. The following image shows the path of vibration from the bones of the skull, past the ear drum and to the cochlea.


Bone conduction is nothing new although its importance in hearing is increasingly recognized.

The Audiphone (, a bone conduction fan of the 1800s, is said to have provided a benefit of up to 30 dB. To use the Audiphone, you would bite down on a diaphragm to enable the sound vibrations to be transmitted by the bone of your teeth.


A recent update to the Audiphone described in a 2012 article in the Denver Post is the SoundBite, a prosthetic device that uses tooth bone to transmit sound by conduction to the middle ear bones. ( A hearing aid placed in the ear canal transmits information to a vibrating device that is held over the teeth like a retainer. According to the Denver Post, the major challenge of creating the device was finding a way to embed miniaturized electronics in a dental appliance.

Another early bone conduction device was held behind the ear, a design that was considered an “elegant” method of hiding a hearing impairment.


The capacity to transmit or strengthen sound by harnessing vibration allows for better enhancement of hearing through hearing aids. When combined with cheap transducers, there are increasing possibilities for new devices as well as for human interaction with them. Breaking the Sound Barrier for Hearing and Gesture ( references new AT&T patents, for example, that allow for “gesture capture” to enable vibrations sent through the body to transmit data to sensors in mobile devices. This would mean that your body could have its own “signature.” It could also allow for interaction with a device without handling it.

Another innovation that relies on bone conduction is the 2015 Hackaday prize-winning entry, the WallTech Phantom, headphones that makes use of a bone conduction amplifier and Bluetooth technology. ( And Google Glass, “smart” eyeglasses, will use bone conduction speakers to convey information to athletes.

I laughed when I came across the Happy Sleep Sound Pillow, a high-density foam pillow that sports a “headphone-free” bone conduction speaker. ( Given the efficient source of transmission from the mobbers to my bed, my own pillow functions more than adequately as a bone conduction speaker for a side sleeper like me.

But how would a bunch of real estate mobbers induce bone conduction in someone sleeping in a bed next door?

I can’t be sure at this point, but like many of the mobbing technologies, it could easily have something to do with radio.

When researching a blog entry I haven’t yet written on the telephone, I ran across a reference to the old tin-can phone with two cans on either side of a line, you know, the kind of phone you might have made as a child. And then I saw references to underground communication systems that use a dipole (two pole) system to convey sound. I began to think about antennas and ground rods.

Think geophysics. And then think about the expertise in geophysics in the building field. There would be no lack of awareness on the part of the kind of expertise that exists in the building trades of how vibrations moves through earth. In my area where small landslides often occur in the winter months and planning to build a home can require an extensive permitting process because of the proximity of Lake Washington, the seismic devices are frequently used to monitor the movement of earth during construction.

I only recently started thinking about this, but especially if you share earth or perhaps even a concrete slab with the houses around you, vibration travels. Wikipedia describes “through-the-earth” signalling such as that used in underground mines and caves as a method of radio signalling that uses low-frequency waves. Conventional higher-range radio signals rely on line-of-sight positioning of antennas and repeaters. That makes me wonder what the possibilities are if you have mobbers working in houses on either side of the lot to be acquired. Wouldn’t that constitute line of sight?

Wikipedia provides information on the radio bands used for ultra low frequency broadcasts at The site also includes a detailed description of Radio Spectrum at A particularly interesting table shows how radio spectrum is broken into bands from low to high frequency, including those that fall into the hackers’ realm of wireless and cellular radio as well as Bluetooth, ZigBee, satellite and GPS. These combined with the more traditional bands of amateur radio and television, could perhaps be said to make up the “mobbers’ radio spectrum.”
