ABSTRACT:
An elastic membrane (14) forms the circumferential surface of a hearing aid which is individualized by a body cast in an auditory canal or in a model of an auditory canal. The membrane (14) defines a casting cavity before and during the casting and surrounds the appliance closely in its individualized condition. The membrane is substantially tubular and has thickened, integrated fastening rings (32, 33) around its outer opening (30) and its inner opening (31) with which it is fastenable to other components of the hearing aid. The membrane has a thickness of ca. 0.2 mm in its central region and a thickness of e.g. 1 mm in the thicker end regions. The membrane (14) with the integrated fastening rings (32, 33) is advantageously produced from e.g. a thermoplastic elastomer or from a highly extensible silicon-plastic by injection moulding.
