Abstract:
1. A hearing aid device, comprising: an input converter for recording an input signal and converting the input signal into an electrical signal; a signal processing unit for processing the electrical signal; an output converter for converting the processed electrical signal into an output signal which is perceived by a user as an acoustic signal; a feedback reduction device for an adjustable reduction or attenuation of a feedback signal contained in the input signal which is a part of the output signal and feedback through a feedback path; a signal source for emitting an information signal through the output converter, wherein the information signal comprises a voice containing informational details pertinent to the user, wherein the information signal is acoustically perceived by the user so that the user receives the informational details; a measuring device for detecting a response signal originating from the emitted information signal; and an evaluation and control device to evaluate the information signal relative to the response signal to obtain a measurement of the feedback path, the evaluation and control device arranged to adjust at least one of a plurality of parameters of the feedback reduction device as a function of the measurement of the feedback path.
