Abstract: The invention relates to a method for designing a regulator (15, 17) for a hearing aid (1) in order to compensate for the occlusion effect during the emission of an acoustic useful signal into the ear canal (5) of the human ear. The hearing aid (1) has an earbud (8), which can be introduced into the ear canal (5) and which comprises a speaker (2) for emitting a compensation signal (y(t), y?(t)) into the ear canal (5) and a microphone (3) for capturing an error signal (e(t)) from the ear canal (5), and a control unit (9) for processing the signal to be emitted and the captured signal.
