目的评估船上舾装作业噪声测量中定点采样与个人声暴露计测量结果的差异性。方法采用个体采样和定点采样两种测试方法对舾装作业接触噪声的工种进行测量,并对结果进行对比分析。结果舾装作业噪声测量个体采样和定点采样两种方法的结果差异无统计学意义(P﹥0.05)。结论在制定合理定点定时测量方案后,定点采样和个体采样是无差异的,定点采样可以代替个体采样测量船上舾装作业噪声环境。
Objective To assess the differences between the fixed-point sampling and the personal acoustic exposure meter measurement in the noise measurement of outfitting operations on ships. Methods Two kinds of test methods, individual sampling and fixed sampling, were used to measure the contact noise of workers, and the results were compared and analyzed. Results There was no significant difference in the results of the two methods for measuring the noise of outfitting homework (P> 0.05). Conclusion Fixed-point time-lapse measurements are not different between fixed-point sampling and individual sampling. Fixed-point sampling can be used instead of individual sampling to measure the noise environment of outfitting on board.
