About this trial
The purpose of this clinical investigation is to develop pre-processing strategies to enhance speech and reduce noise for CI listeners. The Clinical Investigation will be comprised of several arms which will aim to optimize speech enhancement algorithms, to improve real-world functionality, and to incorporate them efficiently into CI speech processors.
Eligibility criteria
Qualifiers
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).
