A total of 328 blacksmiths was examined so as to obtain and analyse the physical parameters of noise exposure for its hygienic evaluation and norm setting. The noise parameters were found to vary according to different criteria if underassessed by means of existing standard 3223-85. Comparative study of hearing loss in the blacksmiths according to a standard 1999 revealed a hyperaggressiveness of impulsive noise in close connection with both noise level and length of service. Impulsive noise was recommended to be evaluated according to the peak level and quantity of impulses, but the basement of MAL is possible with the help of standard pattern while the criteria as length of service, quantile of population and the grade of hearing loss are chosen.
共对328名铁匠进行了检查，以获取并分析噪声暴露的物理参数，用于卫生评估和标准制定。如果按照现有标准3223 - 85进行评估不足，发现噪声参数会根据不同标准而有所变化。根据1999年标准对铁匠听力损失的比较研究表明，脉冲噪声的高攻击性与噪声水平和服务年限密切相关。建议根据脉冲峰值水平和脉冲数量来评估脉冲噪声，但在选择服务年限、人群分位数和听力损失等级等标准的情况下，借助标准模式有可能确定最大允许水平（MAL）。
