Diffuseness quantification in an acoustic test chamber using the isotropy derived by the angular spectrum of sound waves based on the spherical harmonics expansion

Spacecraft are exposed to acoustic loads during flights to space by launch vehicles. The endurance of spacecraft structure is verified by a ground acoustic test specified in test standard documents of the aerospace community. These standard documents require the execution of ground acoustic tests in...
