Abstract:

This report is a study of the effect of changing meteorological conditions on the sonic boom produced during steady level flight. The influence of variations in atmospheric temperature, pressure, and wind on this noise are investigated. Simplified methods are established for estimating the effect of these variations. Combinations of meteorological conditions which can produce anomalous propagation such as complete cut-off, focusing, and extreme lateral spread are discussed. The effect of air turbulence near the ground is considered. A number of comparisons with test data measured at Oklahoma City 1964 are presented, and recommendations for additional experimental and theoretical work are outlined.
