It has been an acceptable conclusion that the vector sound intensity array can estimate the direction of sound sources in high precision in an isotropic noise field, but the error in anisotropic noise field has not been systematically studied yet. The error in doa estimation caused by an anisotropic noise field is analyzed in detail here by taking the ocean surface noise field introduced by cron and...
Efficient and reliable operation is the main requirement of the modern power plant, hence it's significant that the boiler tube leakage source is localized precisely. The four-element acoustic array was exploited in the furnace, a set of hyperboloidal equations are established and the sensors distributed for capture the leakage signal is given. In order to avoiding initial guess and distant source...
