Experience-dependent learning of auditory temporal resolution: evidence from Carnatic-trained musicians.

Abstract
Musical training and experience greatly enhance the cortical and subcortical processing of sounds, which may translate to superior auditory perceptual acuity. Auditory temporal resolution is a fundamental perceptual aspect that is critical for speech understanding in noise in listeners with normal hearing, auditory disorders, cochlear implants, and language disorders, yet very few studies have focused on music-induced learning of temporal resolution. This report demonstrates that Carnatic musical training and experience have a significant impact on temporal resolution assayed by gap detection thresholds. This experience-dependent learning in Carnatic-trained musicians exhibits the universal aspects of human perception and plasticity. The present work adds the perceptual component to a growing body of neurophysiological and imaging studies that suggest plasticity of the peripheral auditory system at the level of the brainstem. The present work may be intriguing to researchers and clinicians alike interested in devising cross-cultural training regimens to alleviate listening-in-noise difficulties.
