title: Noise as a health hazard in the boilermaking industry.
abstract: An investigation was made into noise hazard aspects of three boilermaking firms. This consisted of noise measurement of both background and impact noises, of field audiometry of the workforce and a questionnaire. Environmental findings so far show the noise to be hazardous to hearing. Audiometric testing revealed a high rate of hearing impairment. A general lack of knowledge of noise hazard was shown, and the need for a hearing conservation programme demonstrated.
