Abstract
As part of the NASA Low Boom/No Boom flight test project, a series of low‐amplitude sonic‐boom tests was completed over a 3‐week period in June of 2006. This series of flight tests was designed to evaluate indoor/outdoor human subjective response, structural acoustic building response, and the effects of atmospheric turbulence for low‐amplitude sonic booms characterized by overpressures in the nominal range of 0.1 to 0.6 pounds per square foot (psf). Low‐amplitude sonic booms were generated by F‐18 aircraft using dive trajectories to produce a range of overpressures at the Edwards Air Force Base housing area. In addition, straight and level supersonic flights were used to generate normal level (nominally 1.4 psf) sonic‐boom overpressures at the housing area. This report will describe the structural acoustic building response measurements obtained during this flight test project. A single‐family ranch‐style home was instrumented with nearly 300 microphone and accelerometer sensors to determine the incident pressure and the building’s structural acoustic response. Data were acquired for over 100 sonic‐boom events. The test setup will be described and analysis of the measurements will be presented.
