New Algorithms to Signal Processing for Speech Enhancement in Adult Cochlear Implant Recipients.
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.
Study details:
This is a feasibility, prospective, multi-center, single-subject, repeated-measures clinical investigation in experienced adult cochlear implant users. The Master Umbrella design will enable the execution of a series of sub-investigations in the same user population, with the goal to evaluate a range of speech enhancement pre-processing algorithms in separate sub-investigations. The primary objectives for each sub-investigation will be consistent with the master umbrella investigation, with secondary and exploratory objectives selected based on the algorithm to be investigated.
Secondary and exploratory objectives will be described in the sub-investigation documentation.

What is the study measuring?
Primary outcome
Primary Outcome Measure | Primary Outcome Description | Primary Outcome Time Frame |
---|---|---|
Australian Sentence Test in Noise (AuSTIN) | To determine whether the research algorithm provides non-inferior performance to the standard-of-care algorithm for sentences in noise using an adaptive sentence test in noise scores. Scoring: AuSTIN is scored as a Speech Reception Threshold (SRT), which reflects the volume of speech signal (in decibels, dB) relative to the background noise required for the subject to achieve 50% correct. For example, a score of 2dB SRT means the subject requires the speech to be 2dB louder than the background noise in order to correctly identify 50% of the target sentence. Range: -30dB to +30dB. Lower scores reflect a better outcome. | 1 day - Immediately post-screening |
