Interventions

Categorical loudness scaling based fitting using the research fitting system.device

The research fitting 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.

Behavioural fitting using Custom Sound Suite (CSS 6.3) Softwaredevice

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