GUIDA, Heraldo Lorena; MORINI, Renata Graziele  and  CARDOSO, Ana Cláudia Vieira. Audiological evaluation in workers exposed to noise and pesticide. Braz. j. otorhinolaryngol. (Impr.) [online]. 2010, vol.76, n.4, pp.423-427. ISSN 1808-8694.

Noise-induced hearing loss has been studied for many years and today many experts also investigate the synergic action of chemical products, since they can be potentially ototoxic. AIM: to investigate the audiological findings in workers exposed to occupational noise and pesticide and to compare it to data from noise-exposed workers. STUDY DESIGN: Clinical retrospective. MATERIAL AND METHOD: individuals that had been exposed to pesticide and noise (group I), and individuals that had been exposed to noise only (group II). RESULTS: The classification of the audiometric findings showed in that group I: 35% had normal hearing thresholds, 53.75% had degree 1 hearing loss and 11.25% had degree 2 hearing loss; and group II had 57.5% of normal hearing, 40% had degree 1 hearing loss and only 2.5% had degree 2 hearing loss. The analysis of the audiometric findings also showed a significant worsening after comparing groups I and II thresholds, in the frequency of 3 kHz on the left ear and 4 kHz on both ears. CONCLUSION: The analysis showed that group I had worse audiometric thresholds compared to group II.
