Abstract

Noise and hearing ability profiles were determined in a textile factory in Vietnam. Noise mapping done in the weaving section showed that the noise levels exceeded the Vietnamese standard of 90dBA by as much as 9dBA in some areas. Audiometric tests performed on 69 female workers from the weaving section revealed that workers with more than 10 years of noise exposure had the worst hearing threshold levels at 1, 000 and 4, 000Hz. Similar findings were observed for workers greater than 35 years old. The 4, 000Hz notch, suggestive of exposure to intense noise, was noted in the audiograms of 26 subjects.
