Configurable hearing system

A configurable hearing system that allows a user to compare perception of different hearing aid models corresponding to different performance categories in multiple acoustic environments, the system comprising

• a hearing device, e.g. a hearing aid, adapted to be worn by a user and adapted for processing an input sound signal and/or a directly received auxiliary audio input signal, and providing an enhanced output signal, the hearing device comprising
• a memory storing at least two different performance categories, each comprising a set of technical features representative of a different hearing aid model, each set of technical features including at least one technical feature that is not part of the intersection of the two sets of technical features and each technical feature of the group of technical features being defined by specific parameter settings intended for use in all acoustic situations;
• a forward signal path comprising
• an input unit comprising one or more input transducers for providing respective one or more electric input audio signals representative of said input sound signal and/or one or more wireless receivers for providing respective one or more directly received auxiliary audio input signals;
• a configurable signal processing unit adapted to access the memory and for selecting and processing one or more of said electric input audio signals and/or one or more of said directly received auxiliary audio input signals, based on the set of technical features corresponding to the performance category representing a currently selected one of the different hearing aid models, said configurable signal processing unit providing an enhanced audio signal;
• an output unit for providing said enhanced output signal as stimuli perceivable by the user as sound based on said enhanced audio signal or a signal derived therefrom;
• and
• a user interface configured to allow a user to select any one of said at least two different performance categories comprising a set of technical features representative of a different hearing aid model to be active at a given time;
• wherein the hearing device is configured to provide that at least some of said technical features can be enabled or disabled as part of the specific performance category parameter setting.
