Analysis of overall noise levels from space vehicle launches

A previous paper [L. T. Mathews et al., J. Acoust. Soc. Am. 146, 3043 (2019)] described acoustical measurements made of Falcon 9 space vehicle launches, as measured from various locations within a community near Vandenberg Air Force Base. This paper investigates the directivity pattern measured at one of the launches and compares it with historical and recent literature. Comparisons are made for peak directivity angle and corresponding level at that angle, directivity pattern shape, and calculated overall power level. Results are connected to relatively simple models based on a few engine parameters.
