NCT00205881

Brief Summary

Normal hearing listeners gain important everyday benefits from listening with two ears (bilateral hearing) compared to their baseline performance with hearing aids. Advantages of bilateral hearing include the ability to determine where sounds are coming from and the ability to hear sounds and understand speech in noisy environments. Based upon these advantages, this study will (1) evaluate the benefit of hearing with two Bionic Ear implants (one in each ear) and (2) compare HiResolution sound processing with conventional sound processing.

Outcome Measures

Primary Outcomes (1)

  • Comparison of Pre-implant Consonant-Nucleus-Consonant (CNC) Scores to Post-implant CNC Scores in Bilateral Users.

    Participants were tested on 50 monosyllabic, phonetically balanced words from the Consonant-Nucleus-Consonant (CNC) set, prior to implantation and after bilateral implantation. Percent correct scores for the CNC test are reported.

    8 months of bilateral cochlear implant use

Secondary Outcomes (1)

  • HINT Sentences in Noise

    8 months of bilateral cochlear implant use

Study Arms (1)

ACTIVE COMPARATOR

Bilaterally Implanted with HiRes 90K device.

Device: HiRes 90K Bionic Ear System
