近十多年来,一批消声效果好、阻力损失较小的消声器系列为噪声控制发挥了积极作用.随着国内噪声控制技术的发展,新型消声器系列也在不断涌现.在研制工作中、越来越重视消声器多项综合性指标的提高,即:单位长度或体积内消声量的增高、阻损降低、外形尺寸相对较小、重量轻、安装简便等,以使新
In recent ten years, a batch of muffler series with good anechoic effect and less resistance loss has played a positive role in noise control.With the development of domestic noise control technology, a new series of mufflers are also emerging.During the research and development work, Pay more and more attention to the improvement of a number of comprehensive indicators of muffler: the increase of noise reduction per unit length or volume, the reduction of resistance loss, the relatively small size, light weight, easy installation, etc.,
