[On the modeling of acoustic perception in patients with implants].
Four laws of the spectrum division into frequency bands programmed into the implant Combi-40 were applied. After processing of the speech tables using specially developed program, frequency-restricted speech signal was obtained. It contained 8 bands covering 50 Hz each. These were central frequencies of band filters of the speech processor. Training was needed for all examinees with normal hearing to master a new speech picture after which words differentiation reached 100% in all the four variants of the spectrum division. Thus, excess of speech in terms of frequency representation is more than 92.3%. Parallels are given between speech perception of patients with implants and perception of speech changed according to the above program by subjects with normal hearing.
