Abstract
ClearVoice™ enables Advanced Bionics cochlear implant users to improve their speech understanding in difficult listening environments, without compromising performance in quiet situations. The aim of the study was to evaluate the benefits of ClearVoice in children.Children between six and fourteen years of age randomly tested two modalities of ClearVoice for one month each. The baseline program, HiRes 120™, and both ClearVoice programs were evaluated with a sentence test in quiet and noise. Parents and teachers completed a questionnaire related to everyday noisy situations.The switchover to ClearVoice was uneventful for both modalities. Adjustments to thresholds and comfort levels were required. Seven out of the nine children preferred a ClearVoice program. No impact of ClearVoice on performance in quiet was observed and both modalities of ClearVoice improved speech understanding in noise compared to the baseline program, significantly with ClearVoice high. Positive outcomes were obtained from the questionnaires and discussions with parents and children.This study showed that children benefited from using ClearVoice in their daily life. There was a clear trend towards improved speech understanding in noise with ClearVoice, without affecting performance in quiet; therefore ClearVoice can be used by children all day, without having to change programs.

Summary
ClearVoiceTM enables Advanced Bionics cochlear implant users to Children receiving a cochlear implant at an early age are likely improve their speech understanding in difficult listening environ- to achieve performance levels approaching that of their normally hearments, without compromising performance in quiet situations. Parents and teachers were asked to complete the questionnaire at first group, a second group of three younger subjects aged 6.6 years to the end of each session; baseline for the HiRes 120 program and after. They subjects were evaluated with their baseline HiRes 120 program. The fitting parameters were kept the same as those of the baseline program HiRes 120, except for the most comfortable levels (M-levels) and the threshold levels (T-levels), which were adjusted according to the feedback of the child This program was immediately assessed with speech testing in quiet and in noise, providing a measure of the ClearVoice acute condition.
