分析来自矿山安全和健康管理局(MHSA)的超过700,000个横截面测量数据，并开发统计模型来预测工人的噪声暴露。描述性统计用于汇总数据。使用两个线性回归模型分别基于MSHA允许暴露限值(PEL)和行动水平(AL)来预测噪声暴露。两次交叉验证被用于比较模型中的暴露估计值与坚持数据中的实际测量值。计算每个职称的平均差值和t统计量，以确定模型暴露预测是否与实际数据有显着差异。测量是通过信息自由法的要求从MSHA获得的。从1979年到2014年，平均噪声测量值有所下降。在2000年MSHA修订的噪音法规实施之前进行的测量平均比该法律生效后高出4.5分贝。这两个模型产生的平均暴露预测与坚持数据相比相差不到1dBA。矿场的整体噪音水平一直在下降。然而，这一下降在所有矿业部门并不是一致的。该模型的暴露预测将有助于预测采矿业工人的听力损失。
To analyze over 700,000 cross-sectional measurements from the Mine Safety and Health Administration (MHSA) and develop statistical models to predict noise exposure for a worker. Descriptive statistics were used to summarize the data. Two linear regression models were used to predict noise exposure based on MSHA permissible exposure limit (PEL) and action level (AL) respectively. Two-fold cross validation was used to compare the exposure estimates from the models to actual measurements in the hold out data. The mean difference and t-statistic was calculated for each job title to determine if the model exposure predictions were significantly different from the actual data. Measurements were acquired from MSHA through a Freedom of Information Act request. From 1979 to 2014 the average noise measurement has decreased. Measurements taken before the implementation of MSHA’s revised noise regulation in 2000 were on average 4.5 dBA higher than after the law came in to effect. Both models produced mean exposure predictions that were less than 1 dBA different compared to the holdout data. Overall noise levels in mines have been decreasing. However, this decrease has not been uniform across all mining sectors. The exposure predictions from the model will be useful to help predict hearing loss in workers from the mining industry.
