Because each semicircular canal has its own nerve, a vestibular implant may actually be easier to perfect than a cochlear implant, which has to deliver many different soundfrequencies to a single, bundled auditory nerve.
The isolation cones placed strategically in a tripod pattern at the bottom corners of the sound system reduce the vibration frequencies and provide the most stable supporting structure regardless of the surface on which it rests.
Not only are higher frequencies responsible for the crispness of sound and for being able to cut through background noise, but the comprehension of spoken language relies heavily on vowel sounds in these higher registers.
