The Saturn V is a monument to one of mankind's greatest achievements: the human Moon landings. However, online claims about this vehicle's impressive acoustics by well-meaning individuals are often based on misunderstood or incorrect data. This article, intended for both educators and enthusiasts, discusses topics related to rocket acoustics and documents what is known about the Saturn V's levels: overall power, maximum overall sound pressure, and peak pressure. The overall power level was approximately 204 dB re 1 pW, whereas its lesser sound pressure levels were impacted by source size, directivity, and propagation effects. As this article is part of a special issue on Education in Acoustics in The Journal of the Acoustical Society of America, supplementary Saturn V-related homework problems are included.
土星五号是人类最伟大成就之一的象征
人类登月。然而，一些善意的人对这种飞行器令人印象深刻的声学效果的网络说法往往基于误解或错误的数据。本文针对教育工作者和爱好者，讨论了与火箭声学相关的主题，并记录了已知的土星五号的声压级：总功率、最大总声压和峰值压力。总功率水平约为 204 分贝，而较小的声压级则受到声源尺寸、指向性和传播效应的影响。由于本文是美国声学学会《声学教育特刊》的一部分，因此包含了与土星五号相关的补充作业问题。
