Abstract
The aim is for an LC oscillator circuit of a hearing apparatus to be operated on a sustained basis in a desired frequency range. To this end, a hearing apparatus is proposed having an oscillator and a trimming facility for trimming the oscillation frequency of the oscillator. A control facility controls the oscillation frequency of the oscillator with the aid of the trimming facility in accordance with a predetermined desired value. An automatic self-trimming of a wireless transmission system in a hearing apparatus and in particular in a hearing device is thus possible.
