Middle ear implant for humans.
In humans, a partially implantable middle ear implant (MEI) will first be applied, followed by a wholly implantable MEI, since with the former only an induction coil and a vibrator (to the stapes' head) are used. One of the various advantages of the partially implantable MEI vis-à-vis air conduction hearing aids is that the tone quality is of much higher fidelity, with less noise.
