MAP20071503263Audiometric findings in workers exposed to low levels of styrene and noise / Thais C. Morata... [et al.]Audiometry and exposure measurements were conducted on workers form fiberglass and metal products manufacturing plants and a mail distribution terminal. Workers exposed to noise and styrene had significantly worse pure-tone thresholds at 2,3,4, and 6 kHz when compared with noise-exposed or nonexposed workers.
