متن کاملDYNAMICAL SIMULATION OF UNDERWATER SOUND PROPAGATION IN THE HORMOZ STRAIT
Providing an illustration of sound propagation in the Hormoz Strait ,this paper is about acoustic wave propagation in shallow water for a harmonic point source with low frequency, less than 1000 and solution of a homogenous Helmholtz equation using parabolic equation. C++ programming is used to solve Helmholtz equation [9] and MATLAB software is used to illustrate figures and animate them [6], ...
متن کاملOptimization of Sound Transmission Loss of a Composite Rectangular Plate with Infinite Baffle
In this paper, optimization of the sound transmission loss of finite rectangular anisotropic laminated composite plate with simply supported boundary conditions has been developed to maximize transmission loss. Appropriate constraints were imposed to prevent the occurrence of softening effect due to optimization. For this purpose, optimization process was incorporated into comprehensive finite ...
متن کاملInteractive Edge-Diffraction for Sound Propagation in Complex Virtual Environments
We present an algorithm for interactive computation of diffraction paths for geometric-acoustics in complex environments. Our method extends ray-frustum tracing [Lauterbach et al. 2007] to efficiently compute volumetric regions of the sound field caused by long diffracting edges. We compute accurate diffraction paths from each source to the listener and based on the Uniform Theory of Diffractio...
متن کاملFast Edge-diffraction for Sound Propagation in Complex Virtual Environments
We present an algorithm for fast computation of diffraction paths for geometric-acoustics in complex environments based on the UTD formulation. Our method extends ray-frustum tracing to efficiently compute paths in the shadow region caused by long diffracting edges. Our approach can handle general scenes with moving sources, receivers, and dynamic objects. We evaluate the accuracy through compa...
