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.
Claims24
A method for fitting a multimodal hearing system to a recipient comprising:
- determining a desired perception for an input signal;
- determining two or more stimulation signals, each using a stimulus mode weighting;
- applying said two or more stimulation signals using two or more different stimulation modes, wherein the two or more different stimulation modes comprise two or more of the following:
- an electrical mode of stimulation, an acoustic mode of stimulation produced by an electro-acoustic transducer, a mechanical mode of stimulation, and a photo effect mode of stimulation;
- receiving a measurement of a perception evoked by applying to the recipient the two or more stimulation signals that correspond to the input signal, wherein the two or more stimulation signals are applied using the two or more stimulation modes, and each stimulation signal is determined using respective stimulus mode weightings;
- and
- adjusting one or more of the stimulus mode weightings based on the difference between the measured evoked perception and the desired perception.
A non-transitory computer-readable medium having a computer program for fitting a multimodal hearing system to a recipient, said computer program comprising:
- logic configured to determine a desired perception for an input signal;
- logic configured to retrieve a measurement of a perception evoked by applying to the recipient one or more stimulation signals that correspond to the input signal, wherein the logic configured to retrieve a measurement comprises
- logic configured to apply the two or more stimulation signals using two or more different stimulation modes, wherein the two or more different stimulation modes comprise:
- an electrical mode of stimulation, an acoustic mode of stimulation produced by an electro-acoustic transducer, a mechanical mode of stimulation, and a photo effect mode of stimulation, and
- logic configured to determine each stimulation signal using stimulus mode weighting;
- and
- logic configured to adjust one or more of the stimulus mode weighting based on the difference between the measured evoked perception and the desired perception.
