Acoustic source localization (ASL) or predicting the location of the acoustic source in a structure by analyzing the recorded signals at the receivers is of considerable interest for various applications. Recent research advances on this topic have been limited to homogeneous media. This paper presents a solution for acoustic source localization in a heterogeneous medium without knowing the properties of different materials constituting the heterogeneous structure. In this paper new developments for acoustic source localization in an anisotropic plate is first reviewed briefly. Then an ASL technique is presented for localizing acoustic source in heterogeneous layered structures when the layer properties are not known. The proposed technique is verified experimentally and numerically. The experimental results were generated with a specimen having one interface while numerical results were generated for both two-layered medium with one interface and three-layered medium with two interfaces.
