 In the cochlea, tiny hair cells are distributed all along the hearing organ where they turn sound into electric pulses. The hair cells in the first turn of the cochlea are responsible for higher pitches such as a sound of a bird singing. In comparison, hair cells in the upper turns of the cochlea are responsible for lower pitches, like a bass guitar. With cochlea implants, we bypass damaged hair cells of the cochlea and create electric pulses that stimulate the hearing nerve directly. To mimic all the different hair cells in the different pitch regions of the inner ear, cochlea implants create tiny electric fields along the length of the cochlea. No, there are big differences between different cochlea implant designs when it comes to this. Some implants only stimulate the first turn of the cochlea, the places responsible for high pitched sounds. Such cochlea implants basically just ignore the natural organization of frequencies and change the way, for example, a human voice sounds. And that means your brain will have to work extra hard to adjust to this new and unnatural sound impression. That's why at Medell, we are dedicated to making sure these electric pulses stimulate the right location in the cochlea for a closest to natural hearing experience.
