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.
