本文讨论了一种比以前使用的程序更快速、更简单的噪声等值线生成方法。该方法给出的面积，噪声轮廓，其极端任意复杂的飞行轨迹起飞和着陆相对容易。分析揭示了轮廓的基本性质，以及影响其大小和形状的各种因素如何进入分析。应注意的是，地面衰减和屏蔽的影响被忽略，因为它们只在飞行的初始部分很重要，并且高度依赖于飞机的构型。然而，分析表明，这些影响可以包括在内。强调了单事件等值线是最小化噪声影响的明显选择。
A method for generating noise contours more rapidly and more simply than previously used programs is discussed. The method gives the area, the noise contour, and its extremities for an arbitrarily complex flight path for both takeoffs and landings with relative ease. The analysis reveals the fundamental nature of the contours and how the various factors that influence its size and shape enter into the analysis. It is noted that the effects of ground attenuation and shielding are omitted as they are important only on the initial portion of flight and are highly dependent upon aircraft configuration. However, the analysis shows that these effects could be included. It is emphasized the the single-event contour is an obvious choice for purposes of minimizing noise impact.
