Outcome measures
Primary outcome
Investigate the effect of musical training on the perception of speech in quiet
and in noise, and music perception using pitch, timbre and melody recognition
and enjoyment in normal hearing listeners and cochlear implant users.
The main study parameters are the percent correct scores on each test.
Secondary outcome
Not applicable
Background summary
Cochlear implants (CIs) are prosthetic devices that restore hearing in profound
deafness. Improvements in device design have produced good speech understanding
in quiet, but speech perception in noise and enjoyment and perception of music
are still not satisfactory. This is a factor that could profoundly affect the
quality of life for many CI users, as CI users rank music, after speech
perception, as the second most important acoustical stimulus in their lives.
In addition to potential benefits for quality of life, exposure to music or
musical training may also pose specific benefits for sound and speech
perception. In normal-hearing (NH) listeners, long-term musical experience can
change the sound representation in the auditory system. Enhanced subcortical
and cortical representation of speech and brainstem encoding of linguistic
pitch are observed with musicians. These findings suggest that there may be a
shared neural basis for music and language processing. Perhaps as a result of
this, long-term musically experienced NH adults understand speech in noise
better than non-musicians do. Based on the studies with NH musicians, we have
hypothesized that musical background or musical training might help CI
recipients to have better hearing performance and/or speech perception than
non-musically trained CI recipients.
Our research exploring this hypothesis will provide us a better understanding
of the effect of musical training on the performance of CI recipients and might
lead to the implementation of musical training in the revalidation program of
the CI users and improvements in speech in noise and music perception and
enjoyment and quality of life.
Study objective
Objective: The objective of this study is to identify the effect of musical
training on the perception of speech in quiet and in noise, pitch, timbre, and
melody recognition and the enjoyment of music in normal hearing listeners using
non-processed acoustical stimuli and cochlear implant simulations.
Study design
Study design: Case-control study. The participants listen to acoustic stimuli
and the perception is measured via percent correct scores per test.
Study burden and risks
There are no known risks or benefits associated with the participation in the
experiment. The two sessions last for about 2 hours and adequate breaks are
built into the experiment.
