高、中频混响声场噪声治理技术的研究及应用

我国目前纺织厂织造车间的噪声级均较高。应用吸声降噪原理 ,通过模拟、中试和二项试点三步的实践证明 ,采用在厂房建筑上架设大面积“强吸声吊顶”技术的方法 ,能使织造车间的噪声降低 4～ 6dB(A) ,收到较好的降噪效果。

RESEARCH ON NOISE TREATMENT TECHNOLOGY OF REVERBERATION FIELD WITH HIGH AND MEDIUM FREQUENCES

There is a higher noise level in the weaving workshops of textile factories in China at the present time.It has been proved through simulation, pilot test and two experimental units that the noise in a weaving workshop can be reduced by 4～6 dB(A) if a strong acoustic ceiling with a large area is installed at the mill building, using sound-absorbing and noise-reducing principles.
