A Feasibility, Prospective, Repeated-measures Investigation of Hearing Outcomes With New Pre-processing Speech Enhancement Algorithms Compared to Standard-of-care Algorithms in Adult Cochlear Implant Recipients: a Master Umbrella Investigation
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.
• 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
