The Society of Automotive Engineers Light Vehicle Exterior Sound Committee recognizes the value of preserving historical knowledge regarding the standards developed and reviewed by the committee. To memorialize the knowledge gained and lessons learned over the years, the current committee reached out to the chair of the committee during its formative years, Mr. Richard Schumacher, to discuss the rationale and reasoning for many of the early decisions made regarding vehicle sound standards. This work preserves those discussions and relates the history of some of the most commonly used sound level standards. In this paper and presentation, the formation of the committee is discussed, particularly in relation to EPA’s original concern with vehicle noise, as well as the alignment between SAE standards and ISO standards for vehicle noise measurements. The role of the committee is examined, and the review process for SAE vehicle sound standards is explained.
