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.
