Citation Semi-implantable electromagnetic hearing aids. Lansdale: HAYES, Inc.. Directory Publication. 2011 Authors' conclusions Semi-implantable electromagnetic hearing aids consist of an external audio processor that is worn behind the ear or in the ear canal, a receiver that may be housed with the audio processor or implanted, and an electromagnetic transducer that is implanted so that its tip contacts the ossicles or is close to a magnet implanted on the ossicles. The audio processor detects and converts sounds into electric currents, which are transmitted to the receiver and conveyed to the electromagnetic transducer, where they are converted into a magnetic field that vibrates the ossicles, either by direct contact with the ossicles or by acting on (attracting and repelling) the magnet implanted on the ossicles. These hearing devices are intended to improve hearing acuity in adults with moderate to severe sensorineural hearing loss who will not use or do not obtain sufficient benefit from conventional hearing aids.
