In order to test a hearing aid having at least one microphone, one signal processing unit and one sound transducer, a sound channel is produced between the microphone and the sound transducer. The electrical signal path in the hearing aid is interrupted, and a test signal is fed into the interrupted signal path within the hearing aid, is emitted via the sound transducer, and is passed on through the sound channel to the microphone. The signal received by the microphone is then evaluated.

Method for testing a hearing aid, and hearing aid operable according to the method

In a method for the adaptation of the transmission characteristic of a hearing aid to the hearing aid impairment of a hearing aid wearer using a personal computer having a pointer device such as a mouse, the acoustician selects segments of the graphic presentation of the hearing aid parameters with the mouse, modifies the graphics point-by-point or segment-by-segment by displacement of the mouse and thereby correspondingly co-modifies appertaining, displayable parameters. The hearing aid can be adapted to reach a target characteristic by means of one adaptation procedure, followed if necessary by further analogous fine adaptation procedures.
