摘要

To expedite the efficient analysis for non-lethal acoustic data, a compilation ofdigital signal techniques was formulated and exercised on data being received from acoustic sources and experiments. This compilation with examples is presented as an initial guide to the practical extraction of material acoustic impedance and of signal frequency and energy distribution, for eventual use as inputs for finite element consideration of material acoustic interaction.
