sound exposure level

Conclusion Dosimeter can be used to dynamically measure the real individual exposure level of noise for textile workers, the results measured by dosimeter may be equal or higher than those by traditional sound pressure levels using sound level meter.

结论噪声个体计量仪可以连续动态记录挡车工的实际噪声暴露，其结果高于或等于声级计定点测量结果。

Conclusion Recording sound level meter can be well used to measure and assess noise exposure in complicate working environment.

结论个体噪声暴露测量可以较好地解决现场复杂情况下的噪声暴露评价问题。

In light of sound exposure level for high-speed railway at 15 m from track center, a theoretical model for noise analysis is established by introducing ground attenuation, shielding attenuation and excess attenuation from buildings and trees.

根据离开轨道中心15m处高速铁路的噪声暴露声级，通过引入地面衰减、屏障衰减和房屋建筑及树木的附加衰减参数，建立噪声理论分析模型。

Methods SH-126 recording sound level meters were applied to measure noise exposure individually in two groups of air compressor operators for each workday. At same time working environmental noise levels in the two workshops were also measured using the sound level meter with traditional way.

方法采用SH126记录式声级计测量两组空压工在不同工作日内的噪声暴露，同时用声级计按经典方法在典型工作位多点测量噪声水平。
