Extended high frequency hearing and auditory perception in music professionals

Music-induced hearing loss (MIHL) remains a long-standing concern among music industry professionals who often experience prolonged exposure to potentially hazardous sound levels. Unlike industrial noise, music has distinct spectral and temporal characteristics that may affect the auditory system differently, especially in extended high-frequency (EHF) range. While several studies have examined EHF hearing loss in music professionals, less is known about its impact on speech perception and auditory neural encoding. This study aims to characterize auditory function in music professionals using a comprehensive test battery that includes conventional and EHF audiometry, speech-in-noise tasks, and auditory physiological measures, including distortion product otoacoustic emissions (DPOAEs), auditory brainstem response (ABR), and frequency following response (FFR). Participants with at least 5 years of regular music exposure will complete case history questionnaires, self-report their hearing abilities in daily listening situations, and complete both behavioral and physiological measures. We hypothesize that EHF thresholds, reduced speech-in-noise perception, and differences in neural timing will be observed as indicators of early-stage auditory system changes in music professionals. The degree of these changes will be positively associated with the duration of music exposure. Findings from this study are expected to inform audiological assessment protocols and hearing conservation strategies for music professions.
