摘要
科学证明长期处于噪声环境中有损于人身心健康,建筑材料实验室在进行混凝土搅拌、砂石骨料筛分、钢筋加工等试验时,总伴随着有害于实验人员的噪声污染,而噪声的危害却极易被实验人员所忽视。试验基于此背景在建材实验室中展开,通过声级计定点测量混凝土搅拌、集料筛分、钢筋加工等实验过程的噪声声级值,绘制出声级值时程变化曲线,量化了建材实验室的噪声污染,分析了噪声对实验人员的危害。最后搜集了主要发达国家噪声治理措施,综合实验室实际情况,给出了较为有效的建材实验室噪声控制和治理措施,有利于创造一个更为健康、安全的实验室环境。
Science has proved that being in a noisy environment for a long time can be harmful to people s physical and mental health.When the building materials laboratory is conducting experiments,such as concrete mixing,sand and gravel screening,steel processing and other experiments,there is always noise pollution that is harmful to experimenters.However,the harm of noise environment is easy to be ignored by experimenters.Based on this background,the experiment was carried out in the building materials laboratory.By measuring the noise level of concrete mixing,aggregate screening,steel bar processing and other experimental processes with a sound level meter,we drawn the time-history curve of the sound level value of each experimental process,quantified the noise pollution of building materials laboratory and analyzed the harm of noise to experimenters.Finally,we collected noise control measures in major developed countries,and provided more effective noise control and governance measures for building materials laboratory based on the actual situation of the laboratory,which is conducive to creating a more healthy and safer laboratory environment.
