Semitone Frequency Maps to Improve Music representation for Nucleus
Cochlear Implants

Short Summary
Cochlear implants were originally developed for speech perception. The harmonic structure of
music is not preserved by the standard frequency-to-channel mapping used in CI devices. An
algorithm aimed at remedying this is presented here based on semitone mapping. A sequence
of 36 synthetic complex tones, each consisting of fundamental and 4 harmonic overtones, was
processed using the standard and semitone mappings. The outputs showed that semitone map-
pings preserved the harmonic structure between overtones of all complex tones.
Pitch ranking, Melody contour and instrument recognition tests using
two semitone frequency maps for Nucleus Cochlear Implants

Short Summary
The standard (Std) mapping used in Nucleus cochlear implant (CI) devices distorts the har-
monic structure of complex tones in low frequency ranges. Two semitone-based frequency
maps, Smt-MF and Smt-LF, which preserve harmonic structure representation, are compared
against Std mapping in different psychoacoustic tests with normal hearing (NH) subjects and
CI recipients. Pitch ranking results (NH) showed improvements with semitone mapping. This
was reflected in the melody contour identification results with both NH subjects and CI recipi-
ents. Pitch reversals may occur with Smt-MF when frequencies below 440 Hz are filtered out.
Instrument recognition results were poorer with semitone mapping.

How far cochlear implant strategies have been developed: a comprehensive review

Abstract Over the previous three decades, cochlear implant (CI) devices have been extensively studied. At the outset, CI devices were applied to restore the ability of hearing speech words using simple speech processing. Currently, speech comprehension can be re-stored by CI devices incorporating sophisticated processing strategies, but music per-ception remains generally not appreciable. In particular, many CI recipients report that music is experienced as unpleasant noise despite of the substantial progress in design-ing approaches for music perception. This seems to be strongly related to the CI pro-duction firms which utilize their own strategies that may ameliorate perceiving some features at the expense of others. In this review, different CI strategies will be covered. A new classification based on frequency, time and intensity dimensions will be pro-posed. Finally, whether there is currently a consensus on the “optimum CI devices” will be investigated.

Omran matrix: detecting diagonal activity to quantify harmonic structure preservation with cochlear implant mappings
“Quantifying harmonic structure preservation with Omran matrix”

Abstract
Matrix multiplication is widely utilized in signal and image processing. In numerous cases, it may be considered faster than conventional algorithms. Images and sounds could be presented in form of multi-dimensional matrices. An application under study is to detect diagonal activities in matrices to quantifying the amount of harmonic structure preservation of musical tones using standard and semitone (Smt-MF and Smt-LF) frequency to channel mappings used in cochlear implant algo-rithms. In this paper, a new matrix is proposed that is when post multiplied with another matrix; the first row of the output represents indices of fully active detected diagonals in its upper triangle. Here matrix preprocessing was mandatory prior the detection algorithm. Results showed that Om-ran matrix was powerful in this application illustrating that Smt-LF mapping had the highest pres-ervation of harmonic structures of musical tones followed by Smt-MF and then the standard map-ping.
