About this trial

This is an interventional treatment trial for Sensorineural Hearing Loss, Bilateral

Eligibility Criteria

12 Years - undefined (Child, Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

Newly implanted and existing recipient Groups (Groups 1 and 2):

  • Age 12 and older
  • Monosyllabic word score administered at 60dBA (2 lists) with an appropriately fit hearing aid in the ear to be implanted who are receiving a cochlear implant as standard of care
  • Group 2: 3 months or greater combined experience with commercially available sound processors
  • Fluent spoken English skills

Exclusion Criteria:

  • Unrealistic expectations on the part of the subject regarding the possible benefits, risks, and limitations
  • Additional cognitive, medical or social handicaps that would prevent completion of all study requirements as determined by the Investigational team
  • Unwillingness or inability of the subject to comply with all investigational requirements
  • Use of an acoustic component in the implanted ear
  • Less than 18 active electrodes
  • Hybrid L Cochlear Implant

Outcomes

Primary Outcome Measures

Change in Monosyllabic Word Recognition Scores (CNC) in Quiet
Monosyllabic word recognition was scored in quiet using Consonant-Nucleus-Consonant (CNC) words. Scores are listed as percentage correct thus a higher score (percentage) means a better outcome.Group 1: Preoperative to postoperative percentage performance after 6 months of cochlear implant use. Group 2: Visit A to Visit B after 1 month of cochlear implant use.
