This study aims to investigate the effects of occupational noise exposure on hearing and auditory functions among individuals working in noisy environments. The study evaluates the relationship between occupational noise exposure and hearing-related outcomes.
Male participants aged 20-60 years who had been working at a fuel station for at least two years, had no hearing loss on their pre-employment audiogram, and had no history of balance loss or otologic surgery.
Individuals with middle ear pathology, a history of hearing loss, vestibular disease, or neurological or psychiatric disorders.
Fuel station employees aged 20-60 years and healthy individuals with similar sociodemographic characteristics who had no occupational exposure to noise or chemicals.
