摘要

Similar source method (SSM) has been developed to describe interior and exterior sound field by Too et al. [G.-P.J. Too, TK Su, Estimation of scattered sound field via nearfield measurement by source methods, Appl. Acoust. 58 (1999) 261-281]. The application can be used for arbitrary boundary conditions in terms of acoustic impedance. In the present study, a modified version of SSM is developed to describe the sound pressure distribution in a planar surface. In addition, a signal processing procedure is developed to identify noise source locations. This procedure contains a power spectrum analysis and acoustic holographic analysis to identify different source locations. Several test examples are shown to verify this approach.
