Hearing levels were studied in 948 Alaska pipeline workers. The subjects studied here consist of various kinds of industrial workers and office employees. Hearing threshold of office employees are in general agreement with those of non-industrial populations reported in a few surveys from the literature. Consequently, these data of the office employees are used for controls. Industrial workers over 25 years old are significantly affected with hearing loss, particularly those who work as pipefitters, carpenters, and mechanics. With advancing age, deterioration of hearing occurs in all employees studied here.
对948名阿拉斯加管道工人的听力水平进行了研究。这里研究的对象包括各类产业工人和办公室职员。办公室职员的听力阈值与文献中几项调查所报道的非产业人群的听力阈值总体一致。因此，这些办公室职员的数据被用作对照。25岁以上的产业工人受到听力损失的影响显著，尤其是那些从事管道安装工、木匠和机械师工作的人。随着年龄的增长，这里研究的所有员工的听力都会出现衰退。
