Introduction: Dentists are a vulnerable group who are at risk of hearing loss. This study aimed to investigate the effects of ambient noise on dentists. This cross-sectional study was carried out on residents and professors working in School of Methods: Dentistry in Ahvaz University of Medical Sciences in 1394.
