Abstract
An implantable device for treatment of tinnitus is provided comprising an electronic signal generation unit and a power source for supplying power. A hermetically gas-tight, biocompatible and implantable electroacoustic transducer is also provided as the sound-delivering output transducer which, after an at least partial mastoidectomy, can be positioned in the mastoid cavity such that the sound emitted from the electroacoustic transducer travels from the mastoid to the tympanic cavity via the natural passage of the aditus ad antrum.
