Abstract
An investigation was performed to describe the hearing levels of trainmen and to compare them to those from an appropriate reference population to determine the existence, frequency, and significance of hearing loss for these employees. The major factors which contributed to the measured hearing levels were also identified. Data from the hearing test of 9427 individuals employed as engineers, conductors, brakemen, and firemen for the railroad were included. These men spend most of their work day in locomotive cabs. The data from the male trainmen was grouped by age at the time of the audiometric evaluation. Hearing levels were recorded for each ear and data for the better ear was used in the analysis to enable comparisons to other reference populations. No significant differences were noted between the hearing sensitivity of the trainmen and that of the reference population. Significant differences in hearing levels were noted based on the different age groups, but no differences were noted which correlated with years of service at this job. When evaluated by the risk categories of NIOSH, it was determined that this group of trainmen had no increased risk of loosing their hearing due to their occupation. Trainmen were not determined to be typically exposed to hazardous occupational noise.
