Abstract (en)
[origin: US2006285709A1] With a hearing aid device, filter parameters of filters are to be adjusted for feedback suppression. It is hereby proposed that test signals are emitted via an earpiece in order to estimate the transmission behavior of the feedback path, and response signals to these test signals are recorded by a microphone and analyzed in the hearing aid device. In this way, information signals which are already occasionally emitted by the hearing aid device and can be perceived by the user are used as test signals. Information signals of this type are particularly well suited as test signals and are perceived by the user as non-interfering.
