A potential design window for supersonic overflight based on the perceived level PLdB and glass damage probability of sonic booms is outlined. The evaluation of a simple operational method of estimating the perceived level PLdB of sonic booms is discussed and compared with the Fourier transform computer program calculations of Pease based on the theory of Zepler and Harel. The resulting estimated perceived levels are in good agreement i.e., within 1 to 2 PLdB of each other in the important potential certification or design window that is in the 90 to 100 PLdB range. These perceived levels are shown to be acceptable to 95 to 100 percent of the people exposed to them.
