Relationship between differential auditory sensitivity and central auditory processing among musicians and nonmusicians

Abstract

Abstract Background Music is the art of combining vocals or instruments to form the beauty of expression. Perception of the sounds includes two types of processing: bottom-up and top-down. Earlier studies have reported that musicians outperformed nonmusicians in the discrimination of frequency, intensity, duration, temporal processing tasks, and working memory. The present study compared musicians’ and nonmusicians’ differential sensitivity and auditory processing abilities in children and younger adults. Methods A total of 120 participants in the age range of 9–15 years and 18–25 years were recruited for the study and were further divided into four groups: children musicians, children nonmusicians, young adult musicians, young adult nonmusicians group A, B, C, D, respectively. Each group consisted of 30 participants. Further, all the participants were assessed with Differential sensitivity tests such as DLI, DLF, DDT, GDT, and Dichotic CV. Results The study revealed a high statistical difference in the DLI, DLF, DDT, GDT, and DCV, indicating that children who learned music had better scores than those who did not. A similar trend was observed for younger adults, wherein musicians scored better than nonmusicians on differential sensitivity and auditory processing abilities. Conclusion It was observed that younger adults (musicians and nonmusicians) showed no difference in Dichotic CV, which shows that the maturation and auditory ability of the younger adults are stabilized. Hence, the present study infers that intensive musical training influences superior performance in auditory perceptual tasks.
