A simulation model is developed to estimate acoustic field in the anechoic tank, taking into account secondary reflection, variation of absorption coefficient with respect to the incidence angle, and effects of directional sources.

• 利用虚源方法建立了消声水池声场计算的声场模型,该模型考虑了二次反射、吸声系数随入射角变化、有指向性声源等多种情况。 利用声场模型对水池的声场进行了计算,分别考虑了点声源、吸声系数随入射角变化、二次反射和指向性声源等情况。
