The purpose of this study was to determine prevalence of hearing loss and assess the congruence of perceived hearing loss with the results of audiometric screening in African-American factory workers. This preliminary analysis included data from 252 African-American workers in a Midwestern automotive factory. Subjects were predominantly middle-aged (mean age=47) males (78%) exposed to high noise (mean noise level=92 dB). Actual hearing ability was assessed by audiometric tests conducted for both ears at frequencies 0.5 through 8 kHz, using Tremetrics RA500. Perceived hearing ability was measured by a question about how workers perceive their hearing ability. Prevalence of hearing loss at lower(1-3 kHz) and higher(4 & 6 kHz) frequencies were determined separately. About 16% and 32% of workers showed hearing loss at lower and higher frequencies, respectively. Overall, 18% judged that they had hearing loss. Because a major concern with noise-induced hearing loss is its impact on the ability to perceive speech and communicate effectively in both social and work settings, this study evaluated the congruence of workers' perceived hearing loss with their audiometric test results for speech frequencies. Among those who had hearing loss at speech frequencies, more than half (52%) of the workers perceived that their hearing was good. About 12% of workers with normal hearing test results perceived having hearing loss. This analysis revealed low level of agreement (Cohen's kappa=.34) between the measured and perceived hearing loss in African-American workers.Comparison with results for white workers in the same factory will also be reported.
Learning Objectives: At the conclusion of this presentation, the participants should be able to: 1. Describe the sigficance of occupational noise exposure and hearing loss. 2. Identify the congruence of the measured and perceived hearing loss
