Studies of blast sound propagation and passive absorption using laser-generated shock waves and a semi-analytical method
In this project, a systematic programme of research into the effects of ground elasticity, roughness and curvature on linear and nonlinear near-surface sound propagation is carried out.
This also includes generation of seismic waves by incident airborne shock waves. The high intensity and good repeatability of laser-generated shocks make them a useful source for reduced-scale laboratory investigations.
Rather than to use the completely-numerical methods for modelling blast sound propagation near the source, the project includes investigation and validation of a semi-analytical method of theoretical description of the problem.
