factors that contribute to difficulty in music perception with a CI
factors that contribute to difficulty in music perception with a CI
technological
acoustical
biological
technological
signal converted to electric = degrades music is more complex spectral temporal and timbre larger DR band bass filters for speech signal spectral spread = further degradation
surgical and anatomical factures
array do not reach into apex
4 channels needed for speech and 64 needed for music
rate pitch info
NH - up to 5000
CI - up to 300 HZ
why is live ebtter
recordings are filtered on the way in and out
live has less modification to signal
biological
loss of peripheral nerve fibers and cell bodies lead to the need for increase current levels which causes spread of activation
loss os myelination - increased latencies
PET studies show more cortical activation for speech stimuli = realigned in brain?
acoustical
rhythm - do well
tempo - created mood, remains relatively in tact
melody - many studies do not pair out memory but can do ok with familiar melodies
timbre - tone quality difficult without fine structure
music is presentated as stream with out gaps
if envelopes are similar they fuse
gfeller
nh could discrim instruments in same family
ci made errors across families
pitch perception theory
tonotopic - place of stim
temproal = rate of firing
using non optimal tech
made for speech, trying to hear music
biologic factors
cochlear status and full electrode insertion nVIII status, duration of deafness residual hearing
KIDS DO NOT HAVE COMPAIROSN
MUSIC conseling
reading along, dancing, dont get hung up on dif instruments, rock or rap better avoid loud volumes, and background noise avoid reverb appreciate music in new way PRACTICE solo singer repetition
tips to improve (new listeners)
use accessories, hearing aid in other ear, simple tunes strong beat, keel track, use childrens music
tips for enjoying msuic again
use familiar songs, try different types, repetition
use lyrics
sing along
dance along
pediatrics and music
see how child reacts to different types of music and diff instruments
percussion most enjoyable
keep volume down
