Persistent Monitoring of Urban Infrasound Phenomenology. Report 1: Modeling an Urban Environment for Acoustical Analyses using the 3-D Finite-Difference Time-Domain Program PSTOP3D

Abstract

A 25 square kilometer urban area located in University Park, Texas was modeled using geographic information systems (GIS) software. A smaller 6.25 square kilometer area around the Southern Methodist University was extracted from the larger area and analyzed using an acoustic finite-difference time-domain (FDTD) code. The procedures to model the area using GIS software, extract required data, produce the data files necessary to perform the acoustic analyses, and view the results are described in this report. This report is focused on the details of using the particular software packages used in this study, but the concepts are general in nature and can be applied to other applications if needed.
