In one device, we developed a radio transmitter that had a bandwidth of only 300 Hertz while maintaining crystal clear transmission. Improved signal-processing algorithms are the basis of a new series of Neurophones that are currently under development. The Neurophone is an electronic telepathy machine. Several tests prove that it bypasses the eighth cranial nerve, the hearing nerve, and transmits sound directly to the brain. This means that the Neurophone stimulates perception through a seventh or alternative sense.
All hearing aids stimulate tiny bones in the middle ear.
Sometimes when the eardrum is damaged, the bones of the inner ear are stimulated by a vibrator that is placed behind the ear on the base of the skull. Bone conduction will even work through the teeth. In order for bone conduction to work, the cochlea or inner ear that connects to the eighth cranial nerve first must function. People who are nerve-deaf cannot hear through bone conduction because the nerves in the inner ear are not functional. A number of profoundly nerve-deaf people and people who have had the entire inner ear removed by surgery have been able to hear with the Neurophone.
