1. A method for the adjustment of a transmission characteristic of an electronic circuit installed in a hearing aid (1), comprising the steps of:

  • providing a computing means (2) with a display device (3) and a pointing and/or selecting device (4);

    providing a data transmission connection (6) between the electronic circuit to be adjusted and the computer (2);

    a current transmission characteristic of the electronic circuit is represented by a graphic diagram on the display device (3);

    with the help of the pointing and/or selecting device (4), if and when required, a point (10.1, 10.2, . . .) or a segment of the graphic diagram is selected on the display device (3) and the graphically represented transmission characteristic is changed with the pointing and/or selecting device (4), as a result of which also prescription for modifying certain operating parameters is evaluated, andtransmitting the modified operating parameters to the electronic circuit and storing the modified operating parameters in memory therein; and

    , whereinthe transmission characteristic of the electronic circuit is represented as a structure (8) in a three-dimensional graphic diagram representing at least one of amplification and output sound level as a function of frequency and of input sound level on the display device (3).
