INTERVENTIONAL
Conditions
Summary
The purpose of this clinical investigation is to develop pre-processing strategies to enhance speech and reduce noise for CI listeners. The Master Umbrella Clinical Investigation will be comprised of several sub-investigations, which will aim to optimize speech enhancement algorithms, to improve real-world functionality, and to incorporate them efficiently into CI speech processors.
Eligibility
Inclusion Criteria7
- User of an approved Nucleus cochlear implant.
- User of the ACE (Advanced Combination Encoder) sound processing strategy.
- Aged 18 years or older (no upper age limit).
- Able to score 20% or more at +10 dB SNR or have an adaptive Speech Recognition Threshold (SRT) of 12 dB or less CI alone on a sentence in babble test.*
- Fluent speaker in the language used to assess speech perception performance, as determined by the investigator.
- Willing and able to provide written informed consent.
- ≥3 months post cochlear implant activation
Exclusion Criteria5
- Unable or unwilling to comply with the requirements of the clinical investigation as determined by the Investigator.
- Additional health factors, known to the investigator, that would prevent or restrict participation in the audiological evaluations.
- Investigator site personnel directly affiliated with this study and/or the investigator's immediate families; immediate family is defined as a spouse, parent, child, or sibling.
- Cochlear employees or employees of Contract Research Organizations or contractors engaged by Cochlear for the purposes of this investigation.
- Current participation, or participation in another interventional clinical study/trial in the past 30 days, involving an investigational drug or device (unless the other investigation was/is a Cochlear sponsored investigation and determined by the investigator or Sponsor to not impact this investigation).
