OBJECTIVE

To assess the state of the thresholds of sound perception at speech frequencies in users of cochlear implantation (CI) systems with developed speech skills.

MATERIAL AND METHODS

The study involved 30 patients — users of CI systems, of whom 17 girls, 13 boys aged 6 to 14 years. All patients underwent speech audiometry in a free sound field twice (at the beginning of the study and after adjusting the settings of the speech processor). The ASSR (auditory steady-state responses) thresholds were recorded as the second stage to assess the perception of non-speech stimuli after adjusting the settings of the speech processor.

RESULTS

Correlation analysis was carried out between the percentage of speech intelligibility and the average ASSR thresholds. There was no statistically significant relationship between lowering the ASSR thresholds and speech intelligibility. The absence of a relationship between speech intelligibility and user satisfaction with the speech processor settings was revealed. Improving the intelligibility of the user’s speech by the CI system did not affect the improvement on the response to the addressed speech.
