Abrégé
(EN)
A hearing aid (200) comprises at least one microphone (210), a signal processing means (220) and an output transducer (230). The signal processing means is adapted to receive an input signal from the microphone. The signal processing means is adapted to apply a hearing aid gain to the input signal to produce an output signal to be output by the output transducer, and the signal processing means comprises means for adjusting the hearing aid gain by a direct transmission gain calculated for the hearing aid.
