Noise-induced temporary and permanent threshold shifts of 9 brewery workers were obtained by means of 6 hearing tests during two consecutive days. Subjects had been exposed 6 to 8 hours daily to a bottling noise for approximately 15 years. Results confirm that empirical rules predicting exponential growth and recovery of TTS during and following a work-day apply in men who have a significant permanent threshold shift from repeated exposures to the same work-day noise for a number of previous years.
通过连续两天进行的6次听力测试，获得了9名啤酒厂工人的噪声性暂时性和永久性阈移。受试者每天暴露于装瓶噪声6至8小时，持续约15年。结果证实，预测工作日期间及之后TTS呈指数增长和恢复的经验法则适用于那些因过去数年反复暴露于相同工作日噪声而出现显著永久性阈移的男性。
