摘要：

Simple method for determining sonic boom waveshapes and amplitudes in a still stratified atmosphere is presented. The effects of acoustic impedance, ray tube area, and nonlinear wave steepening and shock formation are each treated separately. By restricting consideration to the waves directly below an aircraft in steady flight, it is possible to present all the information needed to calculate wave shapes and amplitudes without use of a computer. The results for the U S Standard Atmosphere are presented and compared to those calculated for various model atmospheres and to the results of various approximations.
