In healthy skin – healthy hearing

The theory states that the brain uses a holographic coding system, so that it can multivariately encode sensory signals through all the senses. Therefore, any stimulus, like sound, for example, can be transmitted through any other sense organ, in such a way that the brain can recognize the incoming signal exactly as sound, using a special type of signal code for sound.

It seems that, unwillingly, Patrick Flanagan made a significant contribution to the confirmation of this theory when, as a teenager, he invented a device that allows any person (even completely deaf, even with a surgically removed middle ear) and, even more so, fully atrophied auditory nerve) hear through the skin. Patrick called his device “Neurophone” (Neurophone). Interesting story of creating a neurophone.

How it works?

In the early seventies, at the University of Virginia, Dr. Martin Lenhardt and his colleagues showed that both normal hearing people and completely deaf people can perceive ultrasonic frequencies in the range from 28,000 Hz to 100,000 Hz, if the sound comes to body through direct contact with the radiator.

Through experiments, it was found that there are two separate channels through which the brain can hear. One channel – for frequencies from 20 Hz to 20,000 Hz (normal sound). This channel conducts sounds to the cochlea (inner or middle ear) through the air or through bone conduction.

The second hearing channel was opened by Patrick Flanagan in 1958 and explored in the 70s by Dr. Lenhardt and his colleagues. The second channel conducts ultrasound waves through the bones, biological fluids or through the skin to the newly opened new organ of hearing.

Lenhardt argues that the instrument for perceiving ultrasonic vibrations is a small organ located in the brain and known as a labyrinth (organ of balance) – the most important part of the vestibular apparatus. This organ is about the size of a snowflake.

The labyrinth is used by the body to perceive gravity. It is filled with fluid and has fine hairs that extend towards the base. When the position of the head changes, the movement of the fluid stimulates the hairs, telling us where we deviate from the vertical position.

The skin is the largest and most complex organ. In addition to being the first line of defense of the body against infection, the skin is a giant liquid-crystalline brain.

Any organ of perception has evolved from the skin. When a person begins to live as an embryo, his sensory organs develop from the skin folds. Many primitive organisms and animals can see and hear through the skin.

The skin has piezoelectric properties. If you apply vibration to it or rub it, it generates electrical signals and plane waves.

When you use a Neurophone, the skin vibrates at an amplitude modulated carrier frequency of 40 kHz ultrasound and transmits electrical signals to sound through numerous channels to the brain.

The emitters in the first models of the Neurophone had a very original design. They consisted of bulky copper grids for cleaning pans and pots (Brillo mesh) enclosed in plastic bags. The grids were supplied with a voltage of 40 kHz, amplitude modulated with a range of up to 3000 volts (with extremely low current). Although similar devices have been used since the end of the last century “for the treatment of inflammatory processes and the acceleration of the regeneration of affected tissues are absolutely safe, but it is not very pleasant to deal with high voltage all the time – hair moves and goosebumps run around …

Therefore, in order to make the process more comfortable and more efficiently transmit vibration, in 1974, Dr. Flanagan already developed special piezo-ceramic deactivators (ultrasonic emitters on ceramic crystals with piezoelectric properties).

Crystals with piezoelectric properties are compressed and expanded at a frequency equal to the frequency of the electric current flowing over their surface. Vibration from crystals is mechanically transmitted to the skin at the carrier frequency of 40 kHz of the Neurophone.

When the Neurophone’s emitters are pressed to the skin, or when they are joined together, they vibrate in two modes. One is the usual sound, the second is ultrasound, which can be heard only through the skin or through bone conduction. When the “headphones” from the Neurophone are brought into contact with the skin, the ultrasound voice or music begins to be perceived as a labyrinth instead of a snail.

The choice in favor of ultrasound, apparently, is not accidental. Recent studies have established that it turns out that we live in the world of ultrasonic vibrations. Even when a person just walks through the grass, an ultrasound is generated. Each tree is an ultrasound generator that it uses to pump water through the capillaries from the roots to the top. Finally, ultrasonic vibrations with a frequency of 28,000 Hertz are recorded from the palms of a person.
