摘　　要：运载火箭贮箱放气噪声属于空气动力性噪声,这种噪声高达130 dB以上,严重地干扰了正常的测试工作.首先阐述了小孔消声器的消声原理及设计思想,然后依据某型号火箭贮箱放气的有关参数,设计了一种适用于相关系列火箭贮箱放气的小孔消声器.The noise originated from rocket tank deflation belongs to a kind of aerodynamics noise, which could be above 130dB. This seriously harasses the rocket testing. Basing on practicality, the paper firstly sets forth the principle of diffuser muffler and its design essence, and then according to the deflation parameters, gives out a detailed project which is applied to the related series of rockets.
