Comparing the Performance of a Categorical Loudness Scaling Based Fitting With a Behavioural Fitting in Adults With a Nucleus Cochlear Implant 3 Months Post-activation

The Nexus Research system is used in combination with other devices as part of a hearing implant system. It is intended to create and modify hearing profiles, to monitor the performance of the system and to facilitate Firmware updates of the system. It is also intended to be used with other devices of a hearing implant system to make volume adjustments to the processing unit, to download pre-defined MAPs and to collect data from tests and questionnaires using a compatible device.

The comparator is the commercially available fitting method (i.e., the behavioural measurement of active channels) using Custom Sound Suite (CSS 6.3) software
