Patent ID: 7054449

Claim:
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, and transmitting the modified operating parameters to the electronic circuit and storing the modified operating parameters in memory therein; and, wherein the 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 ).
