Treatment and study plan

ClearVoice

Device

ClearVoice is a sound processing strategy designed to improve listening ability in some challenging everyday listening environments for users of the Harmony® HiResolution® Bionic Ear System (Harmony®)

Primary outcomes

  1. Speech Perception of Standardized Sentences Presented From Recorded Format in Speech-spectrum Noise

    Time frame: 4 Weeks

    This was a within subjects design where scores on the AzBio sentence test in speech spectrum noise were compared against quiet scores at the 2-Week and 4-Week Follow-up Visit. The AzBio corpus of sentences consists of 33 lists of 20 sentences each (6 to 10 words per sentence) that have been equated for intelligibility. Two AzBio sentence lists were scored at each follow-up visit (2-Week and 4-Week) with either ClearVoice MEDIUM or ClearVoice HIGH enabled and averaged together. Two AzBio sentence lists were also administered in quiet at each visit. The ClearVoice score minus the quiet score provided the difference in score for the analysis.

Secondary outcomes

  1. The AzBio Sentences Will be Administered in Recorded Format in Multi-talker Babble.

    Time frame: 2-4 weeks
