title: The noise hazard in a large health care facility.
abstract: A noise-level survey, dosimetry, and audiometric testing were conducted in a large health care facility to determine the areas with hazardous noise levels, the number of employees at risk, and the prevalence of noise-induced hearing loss (NIHL) among the exposed. Nine high-risk areas were identified, with readings of up to 110 dBA recorded. In the work force of approximately 6,000 employees, 321 were identified as exposed to potentially hazardous noise levels. Abnormal hearing patterns were observed in 59 (19%) of the 308 workers screened, with 36 cases of NIHL documented. The findings showed that noise is a serious hazard in many areas, that some cases of NIHL have developed from occupational exposure in this hospital, and that a control program is essential.
