*Corresponding author's address: University of Massachusetts at Lowell, Lowell, Massachusetts 01854, Ambika_Bhatta@student.uml.edu This paper investigates the point source response in a medium bounded by two semi-infinite impedance layers. A numerical method to evaluate the internal reflection based on the Laplace transform of the reflection coefficient for each boundary is presented. A description of the branch integral contributing to the reflection coefficient in Laplace domain for single and multiple reflections is given. The analysis utilizes the method of images to model the reflections and to compute the complex pressure amplitude at each image source location.
