The tuning of the speech processors of cochlear implants implies the measurement of the threshold perception levels and the achievement of the maximally comfortable level of loudness in each auditory channel. The authors present a detailed description of the approach to the optimal tuning including the sequence of procedures and manipulations for this purpose, from the first tuning to the achievement of the desired result. This algorithm summarizes the worldwide and the authors' own experience based on the original investigations that have been carried in the Sankt-Peterburg Research Institute of Otorhinolaryngology and Speech during more than 15 years.
