Spacecraft inside a fairing experiences severe high-level random acoustic loads during its launch. To confirm that the spacecraft structures and equipment withstand the launch environment, ground acoustic test is performed in the process of design. Spacecraft is exposed to a diffuse sound field in a large reverberant room during ground acoustic test. On the other hand, spacecraft, especially that has a narrow clearance between spacecraft exterior panel and fairing wall, is exposed to the standing wave sound field, which is called 'Fill Effect', inside a fairing during launch. In this paper, we show the difference of vibration response under standing wave field and diffuse sound field.
