The main aim of this study is to evaluate the hearing health of car wash and auto detailing workers. Audiologic findings of car cash and auto detailing workers in indoor and outdoor environments will be compared with normal hearing individuals. The study included 26 car wash and auto detailing workers working indoors (I-CD), 25 car wash and auto detailing workers working outdoors (O-CD) and a control group of 29 participants. All participants performed a hearing evaluation including Tympanometry, Pure Tone Audiometry (PTA), Transient Evoked Otoacoustic Emission (TEOAE) tests. Tympanometry results, a significant difference was obtained between the groups for left ear canal volume (p<0.05). Significant differences were obtained between the groups for PTA at 250 Hz, 500 Hz and 1000 Hz in the right and 500 Hz in the left ear; for TEOAE at 1000 Hz and 1500 Hz in the right and 1000 Hz in the left ear (p<0.05). Positive significant correlations were obtained between the duration of experience of I-CD workers and PTA at 500 Hz, 1000 Hz and 6000 Hz in the right and 125 Hz in the left ear; and between the duration of experience of O-CD workers and PTA at 2000 Hz in the right, 2000 Hz and 6000 Hz in the left ear (p<0.05).The synergistic effect of noise, chemical components and vibration threatens the hearing health of car wash and auto detailing workers.
