Abstract:
An auditory prosthesis adapted to receive environmental sound which contains a selected auditory component and to supply an auditory stimulus which is perceptible to a user, comprising:a transducer adapted to receive said environmental sound and convert said environmental sound into an electrical input signal containing a selected electrical component corresponding to said selected auditory component in said environmental sound; an adaptive filter receiving said electrical input signal and providing a filtered signal, said adaptive filter having adaptable filtering characteristics based upon a reference and being operable in response to activation to adapt said filtering characteristics using said electrical input signal as said reference to determine said filtering characteristics required to filter said selected electrical component from said electrical input signal, said adaptive filter continuing to provide said filtered signal while adapting said filtering characteristics in response to said activation; a receiver receiving said filtered signal and converting said filtered signal to said auditory stimulus; and user-controlled activation means for activating said adaptive filter at a time controlled by said user, whereby said user can initiate adaptation of said filter without changing operating characteristics of said filter other than as a result of said adaptation.
