Description

Inclusion Criteria:

  • Eighteen years of age or older at the time of the study.
  • Postlinguistic onset of bilateral severe-to-profound sensorineural hearing loss
  • Bilateral severe-to-profound hearing loss that meets current cochlear implant criteria (<50% open-set sentence recognition in quiet scores in the ear to be implanted and <60% in the best-aided condition)

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
CNC Monosyllabic Word Performance - Treated Ear
Time Frame: 12 months
CNC Word Test is a validated test of open-set word recognition. The test consists of 10 lists with 50 monosyllabic words in each list. Subject responses are scored for both words and phonemes correct in the correct sequence. Subjects will be tested using a configuration of speech at 0º azimuth in quiet.
