MUSICAL PERCEPTION AND APPRECIATION AND TEMPORAL ORDINANCE ABILITY IN INDIVIDUAL WITH POST LINGUAL COCHLEAR IMPLANTS

Abstract

Introduction: Studies show that the temporal precision of implanted is impaired due to the processing of electrical signals unrefined. The case of music perception, a process that requires much more refined, will be more difficult to deploy (Gfeller et al, 2008). Therefore, individuals have great difficulty in place to identify songs, number of musical instruments and also what is the instrument played in it. Objective: To evaluate the perception and appreciation of music and auditory skills in subjects implanted temporal ordering post-lingual. Material and Methods: All study volunteers will be informed about the procedures to be performed and sign the consent form had been signed. Will be evaluated 30 patients over 18 years, of both sexes, divided into two groups, GI (control group, 15 normal hearing individuals) and GII (15 post-lingual deaf users of multichannel cochlear implant). The GI group is subjected to basic audiologic evaluation. The group GII will be submitted to pure tone audiometry, free field, to check the audio level of each patient. Both groups will be formed to study applied the proposed TPD and published by Musiek et al in 1990. After completion of the hearing tests will be presented to the patient four songs that differ in the number, tone and melodic range of instruments, the musical texture, the melodic contour, rhythm and how to progress. After the presentation, individuals must complete a questionnaire to evaluate the perception and appreciation of music, proposed by Mascarenhas in 2007. After collecting the data, relevant statistical tests are applied to the analysis of results.
