1. A method for fitting a digital hearing aid, which comprises the steps of:
providing the digital hearing aid having an input transducer, a signal processing device and an output transducer, the signal processing device having an evaluation unit, a comparator unit, a pre-amplification unit and a main amplification unit disposed downstream of the pre-amplification unit;
generating an acoustic test signal by means of an external testing device while the digital hearing aid is worn by a hearing-aid wearer;
generating a digital test input signal by means of the input transducer on a basis of the acoustic test signal;
determining a sound pressure-dependent test quantity on a basis of the digital test input signal by means of the evaluation unit;
determining a deviation between the sound pressure-dependent test quantity and a reference quantity stored in the signal processing device by means of the comparator unit; and
adjusting a pre-amplification by the pre-amplification unit on a basis of the deviation determined.
