ABSTRACTIntroductionResearches into populations with low solvent exposures, or exposures within tolerance levels allowed in the occupational field are still restricted.PurposeTo characterize the hearing profile of gas station attendants.MethodCross-sectional study, constituted of two groups, matched by gender and age: Control Group - 23 subjects without exposure to noise or chemicals; Experimental Group - 21 gas station attendants. An audiological evaluation was performed, composed by pure tone audiometry, speech audiometry and acoustic impedance tests. The statistical analysis used average calculation, standard deviation, minimum and maximum value; Chi-square Test and Pearson’s correlation coefficient. The significance level was 5%.ResultHearing loss was verified in gas station attendants characterized by impairment of the peripheral auditory system, suggesting toxic effects of exposure to fuels. There was a correlation between age and solvent exposure time. Comparing the groups, the acoustic reflex showed more alterations in the experimental group, with a difference for the ipsilateral acoustic reflexes of the right ear and contralateral ones of the left ear.ConclusionThere was no difference between the groups for the hearing thresholds; however, the difference observed in the ipsilateral and contralateral acoustic reflexes in the experimental group suggests retrocochlear impairment. Due to the evidence observed in this study, it is considered relevant to include the acoustic reflex research in the auditory evaluation of the gas station attendants, as well as the integration of this professional category into hearing loss prevention programs.
