The adoption of the OSHA noise amendment has made it necessary to make two different noise exposure measurements. These are the employee's exposure with reference to the action level criteria, which requires a threshold of 80 dBA, and the employee's exposure with reference to the permissible exposure limit, which employs a 90 dBA threshold. In addition to the time constraints involved in measuring employee exposure in relation to two different thresholds, many organizations will not have access to equipment capable of performing these separate tasks simultaneously. Based on 242 simultaneous exposure measurements of both the action level and the permissible exposure level criteria, this paper describes a method which uses one noise exposure criteria measurement to predict an employee's exposure at the other.
职业安全与健康管理局（OSHA）噪声修正案的采用使得有必要进行两种不同的噪声暴露测量。一种是参照行动水平标准对员工的暴露情况进行测量，该标准要求阈值为80分贝声级（dBA）；另一种是参照允许暴露极限对员工的暴露情况进行测量，该极限采用90 dBA的阈值。除了在测量员工相对于两个不同阈值的暴露情况时涉及的时间限制外，许多组织将无法获得能够同时执行这些单独任务的设备。基于对行动水平和允许暴露水平标准的242次同步暴露测量，本文描述了一种方法，该方法使用一种噪声暴露标准测量来预测员工在另一种标准下的暴露情况。
