Abstract

High-frequency energy is generated from nonlinear propagation of finite-amplitude shock waves created by explosions. Energy at these high frequencies may be harmful to bats because their auditory systems use high-frequency information. In April 2005, measurements of blast waves were performed by the U.S. Army. Spectrographic analysis of the waveforms confirms that the high-frequency energy is concentrated near the shocks. The data from these recent experiments serve as a benchmark for analysis of computational model predictions. Using a hybrid time-frequency domain Anderson-type algorithm, the extended generalized Burgers equation is solved for the propagation of a blast wave. Computer code predictions are compared to the benchmark experimental data.
