Abstract
A head-worn hearing aid has a housing composed of two mating shells which contain components including at least one signal receiver, an amplifier and transmission stage, an earphone and a battery. The hearing aid also has formed parts of elastic material disposed in the housing shells, these formed parts lying against the amplifier and transmission stage at both sides when the housing equipped with the device parts is closed, and filling the interspace between the amplifier and transmission stage and the interior surfaces of the housing shells, and holding the amplifier and transmission state in place in the housing.
