Abstract: Method for processing an input signal in a hearing aid, with the input signal being broken down into a discrete signal for each source relative to an acoustic signal, with the discrete signals being assigned to a spatial position of the source and with the discrete signals being output, or output attenuated, relative to the spatial position.

Abstract: A “speech” operating mode is established by a signal processor of a hearing aid for tracking and selecting an acoustic speech source in an ambient sound. The electric acoustic signals are generated by the hearing aid from the ambient sound that has been picked up, from which signals an electric speech signal very probably containing speech is identified and selected by the signal-processor, and the electric speech signal is selectively taken into account in an output sound of the hearing aid in such a way that it will for the hearing-aid wearer acoustically at least be prominent compared with another acoustic source and consequently be better perceived by the hearing-aid wearer.
