Abstract:
An external programmer to be used with a separate programmable hearing aid, the external programmer comprising;circuitry including a neural network for generating a set of hearing aid response defining parameters addressing at least one aspect of a user's hearing impairment in at least one listening environment; circuitry, coupled to the network for entering audiological and other relevant data that characterize aspects of the impairment and of the user; a fuzzy logic processor incorporating rule generating commands for modifying the parameter set based on user-provided responses as a result of the user listening to pre-stored sound stimuli; circuitry for downloading the parameter set to the separate hearing aid; means for generating different prestored sound stimuli for the in situ evaluation of the performance of the hearing aid; means for receiving the user responses to be used by the fuzzy logic processor; means for the online retraining of the neural network after successful fittings; means for the off-line retraining of the neural network from data collected off-site after successful fittings; and means for entering fuzzy processing rules to said fuzzy logic processor.
