Abstract

Frequencies of job injuries, medical problems, and absences were compared for over 400 boiler plant workers in high noise job areas for two-year periods before and after the advance of a hearing conservation program involving use of personal in year protection. Before-after differences in most comparisons were significant and indirection showing fewer job injuries, medical problems, and absences after the advance of the ear protection program. Comparable record data from workers and low noise areas of the same plant showed no substantial changes over the same time periods, suggesting that the observed differences could not be accounted for by plant-wide influences. Relationships between rated use of year protectors and reduced frequency of the extra-auditory problems were not altogether orderly. This finding, plus some alternative explanations tempered the drawing of conclusions that excessive noise is a contributing cause of extra auditory problems.
