Abstract

Pengguna implan koklea dilaporkan masih kesulitan dalam mengapresiasi musik. Penelitian ditujukan untuk mengetahui apresiasi musik pengguna simulasi implan koklea terhadap contour dan temporal cues sebagai cues paling informatif dalam pengenalan medoli, serta pengaruh dari coding strategy. Simulasi implan koklea dilakukan menggunakan coding strategy continuous interleaved sampling (CIS) dan spectral peak (SPEAK) pada variasi jumlah channel 2 sampai 22. Eksperimen di antaranya berupa identifikasi contour, diskriminasi temporal cue, dan identifikasi melodi familier. Pengguna simulasi implan koklea buruk dalam pengenalan contour cue jika dibandingkan dengan normal hearing. Namun, tergolong baik dalam diskriminasi temporal cues dari tempo dan ritme yang divariasikan dengan contour sebab mempunyai skor yang mendekati skor pengenalan normal hearing. Identifikasi melodi familier dengan pitch contour menghasilkan skor yang buruk dibandingkan dengan skor normal hearing, yang berkorelasi (r=0,99) dengan pengenalan contour cue. Informasi temporal cue dari ritme membantu pengguna simulasi implan koklea mengenali melodi familier dengan peningkatan skor hampir 40% dibandingkan melodi tanpa ritme (p<0,05). Jika dibandingkan dengan skor 22 channel sebagai variasi channel terbanyak, apresiasi musik buruk pada variasi coding strategy jumlah channel 2 sampai 6 CIS dan baik pada coding strategy SPEAK untuk semua variasi jumlah channel. Sehingga disimpulkan dari skor performa naracoba, bahwa temporal cues merupakan fitur musik yang paling mudah diapresiasi oleh pengguna simulasi implan koklea, serta perlunya kemajuan coding strategy dalam penyampaian informasi pitch contour cue kepada pengguna simulasi implan koklea.

Cochlear implant users are reported have difficulty in appreciate music. The aim of this study was to determine the musical appreciation of the cochlear implant simulation user on the contour and temporal cues as the most informative cues in recognition of the melody, and effect of the coding strategy. Cochlear implant simulations were processed using continuous interleaved sampling (CIS) and spectral peak (SPEAK) coding strategy on a variety of channels 2 to 22. The experiments included contour identification, temporal cues discrimination, and familiar melody identification. Cochlear implant simulation user are poor at recognizing contour cue compared with normal hearing. However, cochlear implant simulation users are good at discrimination on temporal cues from tempo and rhythm varied with contour and have scores close to normal hearing. Familiar melody identification with pitch contour resulted a poor score compared to normal hearing scores, which correlated (r=0.99) with recognition of contour cue. Temporal cue information from rhythm helped cochlear implant simulation users recognize familiar melodies with an almost 40% increase in score compared to melodies without rhythm (p<0.05). When compared with 22 channels scores as the most channel variation, music appreciation was poor on the variation of coding strategy with the number of channels 2 to 6 CIS and good on the SPEAK coding strategy. It is concluded that from subject’s performance, that temporal cues are the musical features most easily appreciated by cochlear implant simulation users and emphasizes the need for advances in coding strategies in delivery pitch contour cues to cochlear implant simulation users.
