To understand hearing loss, we must know some about the way we hear. We hear in two ways: by conduction of sound energy; and via neural pathways to the brain leading from our cochlea.

Caution should be taken with all metal alloy implants in magnetic fields over 1.5T as the effects from more than 1.5T are currently being studied. Image artifacts should always be taken into consideration with alternative scanning modalities, like CT scanning available.
