Abstract
The present invention provides for fitting a multimodal hearing system to a recipient. Such fitting may include determining a desired perception for an input signal, receiving a measurement of a perception evoked by applying to the recipient one or more stimulation signals that correspond to the input signal, wherein the one or more stimulation signals applied using two or more stimulation modes, and each stimulation signal is determined using stimulus mode weighting, and adjusting one or more of the stimulus mode weightings based on the difference between the measured evoked perception and the desired perception. A multimodal hearing system is able to stimulate using an acoustic, electrical, mechanical mode and/or photo effect mode.
Claims21
A system for fitting a multimodal hearing system to a recipient comprising:
- two or more of the following devices configured to deliver stimulation signal sets to the recipient corresponding to an input signal according to stimulus mode weightings, respectively, wherein at least two of the two or more devices provide different modes of stimulation:
- a mode-E device configured to provide an electrical mode of stimulation;
- a mode-A device configured to provide an acoustic mode of stimulation produced by an electro-acoustic transducer included therein;
- a mode-M device configured to provide a mechanical mode of stimulation, and
- a mode-P device configured to provide a photo effect mode of stimulation;
- an input device for obtaining a measurement of a perception evoked by applying to the recipient the two or more stimulation signal sets, wherein at least two of the two or more stimulation signal sets are for different stimulation modes;
- and
- a processor for adjusting one or more of the stimulus mode weightings based on the difference between the measured evoked perception and a desired perception for the input signal.
The system of 18, wherein:
- the first processor is further configured to alter the frequency by at least increasing the frequency.
