1979年,我厂建起一座临时空压机站。当时,在地上建起的消声滤清室只能把噪声从100～120分贝(A)降至95～100分贝(A)。1981年,我厂又建起一座正规空压机站。考虑到距一车间只有几米远,因此在设计中重新研究了控制空压机站噪声的措施。即在地上消声滤清宇的基础上,将结构加以完善, In 1979, I plant a temporary air compressor station. At that time, the noise reduction filter room built on the ground only reduced the noise from 100 to 120 dB (A) to 95 to 100 dB (A). In 1981, I plant built a regular air compressor station. Taking into account only a few meters away from a workshop, so in the design of the control air compressor station noise measures. That is, on the basis of the sound-absorbing filter on the ground, the structure will be improved,
