Abstract

The correct - optimal - fitting of speech processor determines the best result of rehabilitation. The optimal setting of most comfortable level (MCL) is achieved by accurate patient’s assessment of electrical stimuli loudness. Unfortunately, small children can’t give a reliable report about their feelings. How to determine the MCLs in every channel of children implant? Objective methods don’t give the final (optimal) comfort levels of the child’s working program. Therefore, we need subjective assessments. We tried to use a method of categorical loudness scaling (CLS). This article is a guide how to teach CI children to evaluate loudness. Good results of the CLS were observed.
