Sonic boom propagation into urban landscapes: Preliminary study.

Abstract

In order to characterize the sonic boom response in the interiors of buildings in urban settings, first the loading forces impinging on such buildings must be understood. To do this in an urban setting, many factors must be taken into account including the shape and surface structure of the building of interest, the kind of boom being propagated, and the scale of the propagation space. Nearby buildings and their features also require consideration. In addition, the importance of specular reflection versus diffuse reflections should be addressed. In this study, these factors are discussed and evaluated relative to the impact on the overall sound field. Preliminary results on a simple case are presented. [Work supported by NASA.]
