The majority of college-level musicians exceed the daily recommended noise dose level during instrumental practices and performances, although less than one third report wearing hearing protection while playing their instruments. Although the hazardous effects of music on the auditory system have been established, even in young adult musicians still early in their musical careers, the effects of music on the vestibular system are still unclear. The purpose of the present study was to examine vestibular/balance differences between young adult musicians and nonmusicians to determine the effects of music exposure on the vestibular system. Young adult participants aged 18-27 years without any history of hearing loss, vestibular/balance disorder, otologic disorder, or nervous system disorder were included in this study. Participants were divided into musician (n = 19) and nonmusician (n = 18) groups. Vestibular function was assessed and compared via the cervical vestibular evoked myogenic potential (cVEMP), ocular vestibular evoked myogenic potential (oVEMP), video head impulse test (vHIT), and modified clinical test of sensory interaction in balance (mCTSIB). Musicians were found to produce significantly more saccades in the left horizontal semicircular canal during vHIT assessment compared to nonmusicians. Group differences were not found in the cVEMP, oVEMP, or mCTSIB. This study shows the effects of music exposure on the vestibular system in young adult musicians who show early-onset, subclinical findings on the vHIT that could develop into abnormal results on vestibular assessments if hearing protection use is not increased.
