Music perception in cochlear implant users: an event-related potential study

Music perception in cochlear implant users: an event-related potential study.

OBJECTIVE Compare the processing of music-syntactic irregularities and physical oddballs between cochlear implant (CI) users and matched controls. METHODS Musical chord sequences were presented, some of which contained functionally irregular chords, or a chord with an instrumental timbre that deviated from the standard timbre. RESULTS In both controls and CI users, functionally irregular ch...

Music Perception in Cochlear Implant Users

Melodic contour identification and music perception by cochlear implant users.

Research and outcomes with cochlear implants (CIs) have revealed a dichotomy in the cues necessary for speech and music recognition. CI devices typically transmit 16-22 spectral channels, each modulated slowly in time. This coarse representation provides enough information to support speech understanding in quiet and rhythmic perception in music, but not enough to support speech understanding i...

Event-related potentials for better speech perception in noise by cochlear implant users.

Speech perception in noise is still difficult for cochlear implant (CI) users even with many years of CI use. This study aimed to investigate neurophysiological and behavioral foundations for CI-dependent speech perception in noise. Seventeen post-lingual CI users and twelve age-matched normal hearing adults participated in two experiments. In Experiment 1, CI users' auditory-only word percepti...

Temporal Feature Perception in Cochlear Implant Users

For the perception of timbre of a musical instrument, the attack time is known to hold crucial information. The first 50 to 150 ms of sound onset reflect the excitation mechanism, which generates the sound. Since auditory processing and music perception in particular are known to be hampered in cochlear implant (CI) users, we conducted an electroencephalography (EEG) study with an oddball parad...
