目前我国生产的工业机械设备,在设计与制造上很少考虑噪声防治,以致在运转中辐射出较强的噪声。多数工业机械设备辐射的噪声,其声压级超过噪声卫生标准的规定。某些机械,如柴油机、增压器、燃气轮机,某些类型的空气压缩机、冲床、振动机以及若干试验装置等甚至超过100分贝(A),使工作场所造成严重的噪声污染,不仅影响工作人员的健康,降低劳动效率,而且波及周围居民区,不断发生纠纷,影响了生产及生活甚至造成种种不幸。
At present, China’s industrial machinery and equipment produced in the design and manufacture rarely consider the noise control, resulting in the operation of a strong radiation noise. Most industrial machinery and equipment radiation noise, the sound pressure level exceeds the noise health standards. Some machines, such as diesel engines, turbochargers, gas turbines, certain types of air compressors, punching machines, vibratory machines, and several test equipment even exceed 100 decibels (A), causing serious noise pollution in the workplace, affecting not only work Staff health, reduce labor efficiency, but also spread to the surrounding residential areas, continuous disputes, affecting the production and life even caused all kinds of misfortune.
