Neurofuzzy based device for programmable hearing aids
First Claim
1. A fitting system for programming a separate, programmable hearing aid comprising:
- a programmable processor coupled to circuitry for transferring parameters from the processor to a programmable hearing aid to specify the performance thereof;
software, executable by the processor for presenting pre-stored audio stimuli to the hearing aid and circuitry for receipt of real-time feedback from a user of the hearing aid, the feedback being related to the presented pre-stored audio stimuli;
second software executable by the processor responsive to the user feedback, where the second software implements fuzzy logic processing in responding to the user feedback, to modify the parameters of the programmable hearing aid in accordance with that feedback; and
additional software for downloading the modified parameters to the programmable hearing aid thereby altering the performance thereof.

Abstract
A neurofuzzy device is described that provides a fuzzy logic based user-machine interface for optimal fitting of programmable hearing prosthesis using a neural network that generates targets to be matched by the hearing prosthesis based on individual audiometric and other relevant data to the specific impairment and on the neural network accumulated learning from previous successful fittings. The incorporated learning process can occur on or off line and implements fitting rationales that can satisfy the needs of a general or specific clientele. The parameters of the programmable prosthetic device are set as a group in order to achieve optimal matching to the targets. The user-machine interface realized by a fuzzy logic system deciphers the commends/responses of the user while listening to various stimuli and modifies the targets accordingly thus, providing a closed loop system for in-situ interactive fitting.
