N2 - This paper describes an initial investigation on the reflection of secondary sonic booms, based on the surface topography. It is hypothesized that the type of secondary sonic booms resulting from a primary boom surface reflection could be substantially affected by the topography. A primary boom impacting a flat ocean will provide for a coherent reflected wave. In contrast, a primary boom impacting typical surface topography of the land will produce a more diffuse reflection. Assuming additional propagation effects such as atmospheric absorption would be similar in the two cases, the difference between coherent or diffuse reflections might explain why secondary booms reflecting over typical land surfaces would produce decreased sound levels and therefore be less problematic than for the same booms reflecting over a calm ocean surface.
