The report describes a procedure for predicting the structural and acoustic response of full scale architectural structures to sonic booms using laboratory techniques. It is shown that the essential acoustic properties of a full scale structure located in Istres, France could be accurately simulated on a small scale 120 model located at N.Y.U. and that this model could be used to determine acoustic impulse response functions of various rooms under varying window and door configurations and under varying supersonic flight Mach numbers. The calculated impulse response functions were used in conjunction with measured sonic boom signatures from Mirage III overflights at speeds of Mach 1 and Mach 2 to calculate building responses. These responses were then compared with measured building responses. Author
