ABSTRACT

Objectives: This study aimed to evaluate the benefits of ClearVoice strategy on speech perception in noise and in everyday listening situations in Cantonese-speaking cochlear implant users.

Methods: Twelve experienced adult users of the Harmony implant and HiRes 120 sound processing participated in the study. The study employed a prospective within-subjects design wherein speech recognition in adults using HiRes 120 without ClearVoice turned on (control option) was compared to their performance with HiRes 120 with ClearVoice turned on. Each subject was evaluated with two different ClearVoice gain settings: -12 dB (ClearVoice medium) and -18 dB (ClearVoice high) after one-week of use. The Cantonese hearing in noise test and a questionnaire were used as the outcome measures.

Results: Subjects performed significantly better with ClearVoice medium than with control option in noise. No significant difference in performance was noted among the 3 settings in quiet. Most subjects reported high level of satisfaction with ClearVoice in daily listening situations and preferred to keep ClearVoice on.

Conclusion: ClearVoice can help cochlear implant recipients to hear better in noise.

Figure 6: Distribution of average ratings on the usefulness of ClearVoice (1, strongly disagree; 7, strongly agree).

Mentions: Most of the subjects found ClearVoice useful in the following situations: conversing in a group of people (83%), conversing in a car (75%), conversing in a party or restaurant (75%), and using a telephone or cell phone (75%). Some of the subjects found ClearVoice useful in watching TV or listening to talk radio (50%), listening in a meeting (50%), listening to a public speaker in a church or auditorium (42%), and understanding of words in songs (42%). The percentage distributions on ratings on situational preference are shown in Fig. 5. The subjects were asked to rate the usefulness of ClearVoice in some listening situations on a 7-point scale (1, strongly disagree; 7, strongly agree). On average, the subjects agreed that the ClearVoice makes listening in challenging situations easier, less tiring or stressful, and more enjoyable. Distribution of average ratings on the usefulness of ClearVoice is depicted in Fig. 6.
