Multidimensional coding of stimulation pulses

A hearing device, comprising:

• one or more microphones configured to generate at least one audio signal comprising multiple acoustic parameters;
• a memory unit storing a plurality of multidimensional perceptual models, wherein each multidimensional perceptual model includes perceptual information as a function of coding parameter groups;
• a signal processor unit configured to:
• retrieve a selected multidimensional perceptual model of the plurality of multidimensional perceptual models from the memory unit, and
• use the selected multidimensional perceptual model to convert the at least one audio signal into one or more processed signals such that at least one piece of perceptual information is encoded as function of the coding parameter groups in the selected multidimensional perceptual model;
• and
• a coding unit configured to generate, using the one or more processed signals, stimulation signals for delivery to a recipient of the hearing device.
