Abstract
A hearing aid for compensating for an occlusion effect while emitting an acoustic useful signal into an auditory canal of a human ear comprises an earbud that can be inserted into the auditory canal, a speaker for emitting a compensation signal into the auditory canal, a microphone for receiving an error signal from the auditory canal, and a control unit for processing a recorded signal to be emitted. The controller is designed by measuring a nominal secondary path between a speaker and the microphone and determining a transmission function that describes behavior of the nominal secondary path, determining a first requirement as a tolerance band about the transmission function, determining a second requirement as a desired sensitivity function of the hearing aid, designing the controller using an optimization method while simultaneously taking the first and second requirements into consideration, and implementing the controller in the control unit.
