摘　　要：在大推力氢氧火箭发动机试验中,噪声问题越来越突出,有必要对其采取噪声治理措施。总结大推力氢氧火箭发动机噪声治理的难点和影响大推力氢氧火箭发动机噪声治理的因素,介绍大推力氢氧火箭发动机高空模拟试验和地面试验的降噪方法,并对喷水降噪后进一步的噪声治理措施给出建议。In high thrust LOX/GH2 rocket engine tests, noise reduction issues have become more serious. In this paper, the difficulties and influencing factors in the noise control were summarized. Noise control methods in the ground tests and altitude tests of the high thrust LOX/GH2 rocket engines were introduced respectively. After the water injection noise reduction method, some suggestions for further noise control were proposed.
