To assess the results of rehabilitation of patients after cochlear implantation (CI) the following examinations were performed: free field speech audiometry in noise using the Russian-language version of the international phrasal test RUMatrix; spectral temporally modulated ripple test (SMRT); registration spread of electrical excitation (SOE). The research was conducted on 15 normally hearing native Russian speaking participants together with 20 cochlear implanted patients. The study shows that there is a correlation between speech intelligibility in noise and spectral hearing resolution. Therefore, SMRT could be recommended for the assessment of CI patients’ rehabilitation regardless of their level of speech development.

Key words: cochlear implantation, free field speech audiometry, spectral hearing resolution, RUMatrix test, SMRT, spread of electrical excitation (SOE)
