A continuous structure has several response characteristics that make it a good candidate for a sensor to be used in locating an acoustic source. In this paper, based on a beam structure with simple supports on both ends, the response of the structure to transient sinusoidal wave excitations is examined analytically and also verified by a finite element method (FEM). For sensor configuration on this structure, various interesting parameters such as the aperture of the structure, material properties, and thickness are examined by evaluating their effects on structure displacement responses. Results will be used for acoustic wave identification in the future.
