ABSTRACT:
A method for adjusting a transmission characteristic of an electronic circuit, in a hearing aid. The hearing aid is connected with a computer. The current operating parameters of the hearing aid are transmitted to the computer. The computer from the operating parameters, calculates the current transmission characteristic and represents it on a monitor screen as a three-dimensional graphic diagram. The acoustics specialist, with the help of a mouse, selects a point of a segment of the graphic diagram and modifies the graphically depicted transmission characteristic. As a result the current operating parameters are modified as well. From these, a new current transmission characteristic is calculated and represented on the monitor screen as a three-dimensional graphic. This adaptation process is repeated until the current transmission characteristic coincides with the desired response. Then the current operating parameters are transmitted from the computer to the hearing aid and there stored in memory.
