Contour identification with pitch and loudness cues using cochlear implants.
Different from speech, pitch and loudness cues may or may not co-vary in music. Cochlear implant (CI) users with poor pitch perception may use loudness contour cues more than normal-hearing (NH) listeners. Contour identification was tested in CI users and NH listeners; the five-note contours contained either pitch cues alone, loudness cues alone, or both. Results showed that NH listeners' contour identification was better with pitch cues than with loudness cues; CI users performed similarly with either cues. When pitch and loudness cues were co-varied, CI performance significantly improved, suggesting that CI users were able to integrate the two cues.
