摘要：Frequency averaged normal-derivative Helmholtz integral equation is proposed to get robust predictions of the frequency averaged quadratic pressure (FAQP) radiated from the structures at medium and high frequencies. The non-uniqueness problem of frequency averaged Helmholtz integral equation and frequency averaged normal-derivative Helmholtz integral equation is overcome by the coupling method combining these two integral equations. The numerical examples are given to demonstrate the versatility of the frequency averaged normal-derivative Helmholtz integral equation and the coupling method. (C) 2017 Elsevier Ltd.
