- In area where noise does exceed safe exposure limits, are the workers required to wear personal protective equipment (PPE) for hearing? 在噪音超标区域,工人是否被要求穿戴个人防护用品以保护听力?
- Threshold limit of cumulative noise exposure 累积暴露噪声阈值
- Consult local authorized for acceptable exposure limits. 谘询地方当局的专家;可接受的曝露范围.
- Based on two sets of data from occupational epidemiology, Benchmark dose(BMD) was applied to estimate biological exposure limit (BEL). 根据职业流行病学资料,研究基准剂量(BMD)在制定生物接触限值中的应用。
- The average level of occupational noise exposure of female workes of Anqing Textile Factory and urban community were 98.1 dB and 58.1 dB respectively. 应用单因素的卡方检验和方差分析及多因素的广义线性模型分析得到如下研究结果:(1)纺织厂女工职业噪声暴露的平均值为89.;1dB;社区工作的对照女工噪声暴露的平均值为58
- The EEL represents a cumulative exposure limit taking into account both the time of exposure and the concentration at which the exposure occurs. eel代表了一个既考虑了暴露时间又考虑了暴露发生时的浓度的累积的暴露极限。
- Objective: This panel study aimed to investigate effects of occupational noise exposure on ambulatory vascular structural properties in male workers. 目的:探讨职业噪音暴露对男性工人之动态血管构造特性的影响。
- The result showed that after 95 dB (SPL) intensive noise exposure, the amplitude induced was augmented evindently after 1 kHz tone burst (P<0. 05). 结果在95dB(SPL)强噪声暴露后;1kHz短纯音引起的波幅明显增大(P<0.;05)。

- After noise exposure, the changes and recovery rate of DPO differed from those of CM in all periods. In particular, changes in DPO were greater than those of CM. 暴露后不同阶段DPO和CM恢复的速率和变化程度不同,前者在各个阶段上损失的程度比后者重。
- NIHL can be divided into temporary threshold shift (TTS) and permanent threshold shift (PTS). The TTS can soon recover if we break away from noise exposure. 噪声性听力损失分为暂时性阈移(Temporary threshold shift,TTS)和永久性阈移(Permanent threshold shift,PTS)。
- While exposure at these levels may produce injury, the injury would be reversible. The EEL represents a cumulative exposure limit taking into account both the time of exposure and the concentration at which the exposure occurs. 虽然在这种水平的暴露可能导致伤害,但伤害是可逆的。eel代表了一个既考虑了暴露时间又考虑了暴露发生时的浓度的累积的暴露极限。
- The German occupational exposure limit for fumes and aerosols emitted from hot bitumen is a technical guidance value, which reflects technical feasibility and is not primarily based on toxicological findings. 德国对于沥青烟气和悬浮颗粒的限值只是一种技术性指导数据,反映了技术上的可行性,而主要不是依据毒理学方面的研究得出的。
- Result: The result showed that the prevalence rate of noise induced deafness was27.97%, there was a dose response relation between the incidence of noise induced deafness and the doses of the noise exposure. 结果:结果表明;所调查五金工业噪声作业工人噪声性耳聋患病率为27.;97%25各级噪声性耳聋患病率与噪声接触剂量之间存在着剂量反应关系。
