我们根据回转体模型的水筒噪声试验，分析了不同低表面能涂层模型在高、低频段降低噪声总声级的效果。一些涂层模型在高频噪声声级降低很多时引起了噪声总声级的降低．
Based on the water tube noise test of the swivel body model, we analyzed the effect of different low surface energy coating models on reducing the total sound level of noise in the high and low frequency bands. Some coating models cause a reduction in the overall level of noise when the level of high-frequency noise is significantly reduced.
