AIM: Noise affects hearing and balance functions negatively. The aim of this study is to investigate whether the wind noise that motor users are exposed to, even if they wear a helmet, affects the auditory and vestibular functions.
METHOD: 15 individuals (study group) with normal hearing, who did not have any systemic, neurological and psychological disorders, aged between 18-45 years, who used regular motorcycle for at least 1 year and 15 volunteer individuals (control group) who were not using motorcycle in the same age range. Pure tone audiometry (0,125-18 kHz), Auditory Evoked Cortical Potentials (CAEP) tests were performed. After the auditory evaluations, Sensory Organization Test (SOT) was performed.
CONCLUSION: A significant difference was observed between motorcycle users and the control group at 125, 250, 500 and 6000 Hz (p <0.05). There was no significant difference between other hearing thresholds, in the latency and amplitude complex of P1 / N1 / P2 in CAEP test, and visual, somatosensory, vestibular and proprioceptive mechanisms according to SOT results between study and control group (p> 0.05).
DISCUSSION: Motorcycle users may experience more severe and prolonged exposure to wind noise at 6000 Hz due to noise-related hearing loss. The difference in hearing loss observed at low frequencies such as 125, 250 and 500 Hz affected the cochlea due to the vibration of the motorcycle and was thought to cause hearing loss. Although CAEP and SOT were not significant, it was thought that the sample group should be expanded since noise affects both hearing and vestibular function.
