From: Semitone frequency mapping to improve music representation for nucleus cochlear implants
The frequency to channel assignments for the Smt-LF (filled circles), Smt-MF (filled squares) and Std (open circles) mappings are shown here together with the Greenwood function (dashed line, secondary y -axis). The figure assumes a cochlea length (unrolled) of 33 mm, and illustrates an insertion depth of 22 mm for a Nucleus straight array with 22 equally spaced electrodes. The channel location within the cochlea can be derived from the two y-axes.
