Description

Inclusion Criteria:

  • Unilateral or bilateral user of CII/HiRes90K™ implant(s) (minimum of one year in each implanted ear), Harmony™ BTE processor(s) with HiRes Fidelity 120™ (with or without ClearVoice™) as preferred sound processing strategy
  • 18 years of age or older at time of implant
  • Postlingual onset of severe-to-profound hearing loss (≥ 6 years of age)
  • At least moderate open-set speech recognition abilities (defined as CNC word score ≥ 50% in medical records or assessed at the Baseline Visit with implant alone for unilateral users, with both implants together for bilateral users)
  • English language proficiency
  • Willingness to use a Harmony™ BTE processor and refrain from ClearVoice™ use for the duration of the study
  • Willingness and ability to participate in all scheduled procedures outlined in the protocol

Exclusion Criteria:

• Presence of any additional disabilities that would prevent or interfere with participation in the required speech perception testing

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Control first, then Experimental (Group A)
Initial subject use of Control Sound Processing Strategy for the first week, followed by subject use of Experimental (HiRes™ Optima) Sound Processing Strategy for the HiResolution™ Bionic Ear System for the second week.
Device: Control first, then Experimental
Control condition is currently marketed sound processing strategy.
Experimental: Experimental first, then Control (Group B)
Initial subject use of Experimental (HiRes™ Optima) Sound Processing Strategy for the first week for the HiResolution™ Bionic Ear System, followed by subject use of the Control Sound Processing Strategy for the second week.
Device: Experimental first, then Control
Experimental condition is newly modified sound processing strategy.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Speech Perception With Control and Experimental Conditions Both Tested in Quiet, in Speech-spectrum Noise, and in Multi-talker Babble Noise.
Time Frame: 2 weeks
Sentence recognition with the new (experimental) and current (control) sound processing strategies will be compared. Subjects will be tested using the AzBio corpus of sentences, which consists of 33 lists of 20 sentences each (6 to 10 words per sentence) that are equated for intelligibility. The difference between the Control percent correct scores and Experimental percent correct scores will be used for the analysis (Experimental AzBio scores minus Control AzBio scores). Data from both Group A and Group B were pooled for the analysis.
2 weeks
Device-related Adverse Events
Time Frame: 2 weeks
Device-related adverse events will be assessed to determine whether they impact current device safety performance.
2 weeks
