Extracochlear Prosthesis in acute experiment
Vestnik otorinolaringologii, 1992Co-Authors: M R Bogomilskiĭ, I N D Iakonova, A M Tikhomirov, L N FitenkoAbstract:Whether the transfer of coded sound intensity is possible was studied in acute experiments on cats with acquired deafness, using an original transducer of the signals with Extracochlear position of the electrodes. The stimulation results were compared to intracochlear Prosthesis. The type of the stimulation was not essential for threshold values of the total electric impact. In Extracochlear position of the electrodes and the duration of potential 0.2 msec its amplitude increment was the highest, while the dynamic range turned out the lowest. With the impulse duration 0.5 msec, these differences disappeared. When compared to Extracochlear, intracochlear bipolar stimulation proved superior.

A discrimination ability of time sequential signal by electrical stimulation to auditory nerves and its comparison with that by vibrotactile stimulation
Images of the Twenty-First Century. Proceedings of the Annual International Engineering in Medicine and Biology Society, 1Co-Authors: Tohru Ifukube, Y. Hirata, Junichi MatsushimaAbstract:An experiment on the discrimination of time sequential stimuli of auditory nerves was carried out, and its result was compared with results for the vibrotactile sense. An Extracochlear Prosthesis that stimulates via an electrode superficially placed on the round window membrane of the cochlea is described. A new speech coding method is proposed for the Prosthesis, for transmitting the pitch signal and the second formant frequency. In this method, an additional stimulation pulse is inserted among the pitch pulses, and the time delay from pitch to additional pulse is proportional to the second formant frequency. This coding method has been seen to be effective in recognizing about 60% of Japanese vowels. >
