Outcomes

Primary Outcomes

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

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.

Time frame: 4 Weeks

Secondary Outcomes

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

Time frame: 2-4 weeks
