Up to one hundred cochlear implant patients at twelve centers in  the US and Canada have been enrolled in a study of music perception with Nucleus cochlear implants. In addition to monosyllabic word recognition scores and a HINT in noise test, the subjects have been administered a recently validated music perception test, the UW Clinical Assessment of Music Perception (CAMP) test, as well as the Iowa music appreciation questionnaire.  As with other outcome measures in implant listeners, the CAMP test shows great variability across patients. The CAMP test tests pitch direction discrimination, melody identification and timbre recognition. Correlations among the subtests of the CAMP as well as between CAMP scores and tests of speech reception in quiet and noise have been identified in studies at the University of Washington and will be explored in this larger data set. Implications for signal processing with cochlear implants for speech and music will be discussed.
