The hearing conservation records of a large, multiple-facility printing company were obtained. The records were analyzed for factors associated with Standard Threshold Shift. These factors included hearing levels, employee age and sex, occupational and nonoccupational noise exposure histories, and medical history. The analysis revealed that statistically significant factors associated with Standard Threshold Shift were from medical and nonoccupational noise exposure histories, and not occupational noise exposure.
获取了一家大型多厂印刷公司的听力保护记录。对这些记录进行了分析，以找出与标准听阈偏移相关的因素。这些因素包括听力水平、员工年龄和性别、职业和非职业噪声暴露史以及病史。分析表明，与标准听阈偏移相关的具有统计学意义的因素来自病史和非职业噪声暴露史，而非职业噪声暴露。
