Intervention/exposure
Study type
Interventional
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
