Title Combined effects of sound, climate and air pollutants on noise induced hearing loss
Bibliographic information Dec. 1989, Vol.1, No.1, p.41-44. Illus. Bibl.
Abstract In a laboratory experiment, 10 subjects were exposed to various sound loads at air temperatures of 24░C and 35░C. As expected, the greatest threshold shifts occurred at maximum sound and climate loads. A field study was also carried out to investigate permanent hearing loss in groups of welders and machinery and plant assembly workers exposed to a combination of noise and carbon monoxide. Welders suffered hearing damage when the noise limit for hearing impairment was scarcely exceeded, while the risk was relatively lower for the assembly workers with comparatively higher noise levels and lower carbon monoxide exposure. Results therefore indicate a relationship between combined noise and carbon monoxide exposure and risk of hearing damage.
