Abstract: Before the acoustic test of a satellite, much preparation work should be done to find the best testing scheme, such as analyzing the sound spectrum condition, selecting the test devices, optimizing the parameters of the control system, together with system debugging. In this paper, three different types of sound spectrum conditions are presented to illustrate how to find the best testing scheme with high reliability and low cost on the basis of the current test devices for achieving the anticipated sound levels and serving the test purpose.
