Patent No. 3766331 Hearing aid for producing sensations in the brain (Zink, Oct 16, 1973) Abstract A pulsed oscillator or transmitter supplies energy to a pair of insulated electrodes mounted on a person's neck. The transmitter produces pulses of intensity greater than a predetermined threshold value and of a width and rate so as to produce the sensation of hearing without use of the auditory canal thereby providing a hearing system enabling otherwise deaf people to hear. Notes: Description The present invention relates to means and techniques useful in conveying information and is particularly useful in hearing systems for otherwise deaf persons. The present invention is described in specific relation to systems enabling deaf persons to have communicated to them information initially in sound or audible form with such information being transformed into unique pulses that key a transmitter which develops a car
