Abstract

Traditional single acoustic source localization techniques often become challenging when multiple acoustic sources are present on spherical structures. Here, a localization technique for multiple acoustic sources is proposed using the time difference of arrival without knowing the acoustic wave speed in the material. The proposed technique does not require solving a system of nonlinear equations; hence, greatly reduces the complexity of calculation. The method to remove the artifacts is given. A finite element model of a spherical surface was created to verify the proposed acoustic source localization technique. The results of numerical simulation prove the reliability of the proposed technique.
