Description of intervention(s) / exposure
Treatment: Devices - Investigational Pre-Processing Algorithm (Sub A)
Treatment: Devices - Cochlear Limited standard-of-care pre-processing algorithms
Treatment: Devices - Investigational Pre-Processing Algorithm (Sub B)

Other: Investigational pre-processing algorithm/Standard of Care pre-processing algorithm (Sub A) -

Other: Investigational pre-processing algorithm/Standard of Care pre-processing algorithm (Sub B) - Using Spatial Automation Profile


Treatment: Devices: Investigational Pre-Processing Algorithm (Sub A)
The algorithms act upon the digital audio signal received by the microphones and other sensors to enhance speech and attenuate noise prior to encoding the signal for delivery to a cochlear implant via the specified system.

Treatment: Devices: Cochlear Limited standard-of-care pre-processing algorithms
Automatic Gain Control, SNR-NR, Forward Focus

Summary
Brief 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.
