Abstract
The production of an earpiece for a hearing apparatus and in particular for a hearing device is closely tailored to the simulation. To this end, the earpiece of a hearing apparatus to be inserted into an auditory canal is produced by first selecting a virtual raw vent and manufacturing the earpiece with a real vent. A base frequency of the acoustic transmission function of the virtual raw vent is determined. From that, a virtual vent is determined as a function of the base frequency and of at least one predetermined property of the auditory canal or of the earpiece. The earpiece is then manufactured on the basis of the virtual vent.
