In the method for the adjusting of a transmission characteristic of an electronic circuit, for example, in a hearing aid (1), a computer (2) with a monitor screen (3) and a mouse (4) are made ready. The hearing aid (1) to be adjusted is connected with the computer (2) . The current operating parameters of the hearing aid (1) are transmitted to the computer (2). The computer (2) from the operating parameters calculates the current transmission characteristic and represents this on the monitor screen (3) as a three-dimensional graphic diagram. The acoustics specialist with the help of the mouse (3) selects a point of a segment of th e graphic diagram and modifies the graphically depicted transmission characteristic by moving the mouse (4). As a result of this, also the current operating parameters are modified. From these, a new current transmission characteristic is calculated and represented on the monitor screen (3) as a three- dimensional graphic diagram. This adaptation process is repeated for a s lon g as required, until the current transmission characteristic coincides with the desired response. Once this has been achieved, the current operating parameters are transmitted from the computer (2) to the hearing aid (1) and there stored in memory. This method is more intuitive, more graphically vivid and more easily handled than those known up until now, where only two-dimensiona l representations of the transmission characteristic are utilised. The metluod enables a more effective adjustment of the transmission characteristic and, in the case of hearing aids, a bette r hearing.
