Abstract
A hearing aid is fitted to a patient by first creating a filter having a frequency response dependent on the product of the frequency response of a target hearing aid and the inverse frequency response of a master hearing prosthesis that includes a microphone and an electro-acoustic transducer. The patient is then equipped with the master hearing prosthesis and the microphone of the master hearing prosthesis is exposed to an input acoustic signal, whereby the microphone generates an electrical signal. The electrical signal is processed by the filter and the filtered electrical signal is applied to the electro-acoustic transducer, whereby the patient receives an acoustic signal representative of the input acoustic signal modified by the transfer function of the filter.
