Sound Intensity Prediction System (SIPS): Volume I - Reference Manual
Abstract
The Sound Intensity Prediction System (SIPS) is a tool employed to reduce the number of complaints about noise from explosive operations. SIPS combines procedures for conducting explosive operations with an acoustic ray tracing computer code to determine the locations of both noise enhancements and noise reductions. By predicting areas that can expect either increased or decreased noise levels, noise levels in sensitive areas can be determined. Predictions of quiet zones covering those areas indicate the best times to schedule explosive events. This report documents the theory behind SIPS as well as the program's evolutionary process. The different computer models that make predictions about sound distribution are approximately equivalent in their predictive power with different methods of getting results and displaying the output. The quality of SIPS predictions is enhanced by using the model only on days when the weather is stable. In addition, predictions of focusing should be considered as areas rather than points since there is a tendency for them to drift.
