by SAE International in United States
A Society of Automotive Engineers (SAE) Cooperative Research Project has established good correlation between pass-by noise data measured on U.S. test tracks conforming to SAE Sealed (sealed asphalt) and International Standards Organization (ISO) surface specifications. Although the ISO surface has a very specific track composition, it does not reduce the variability of the measurements over an SAE Sealed surface. This paper summarizes the project results and determines that the SAE Sealed surface generally produces slightly louder noise levels than a comparable ISO surface when used for pass-by testing; however, the SAE Sealed surface does not represent a consistent upper boundary for the ISO test data. The data supports the use of either track surface for pass-by procedures and suggests that road texture can influence the tire component of vehicle noise. Although the ISO surface has become the requirement for noise regulations in Europe, development work can be completed on the existing sealed test surfaces.

SAE MOBILUS® Search Tips
Please note: All terms not contained within quotes, will be evaluated using the OR operator. This means that your search results will contain all results that contain ANY of the entered terms.
AND, OR, NOT
SAE MOBILUS supports the use of the AND, OR and NOT BOOLEAN operators ONLY function with the Advanced Search.
Using the asterisk, ( * ) allows you to search for a partial word. For example, entering a keyword search of aero* will search for any word beginning with aero.
Using the question mark, ( ? ) allows you to search for a word with a single character wildcard. For example, searching for t?re would match both tire and tyre
Words in double quotes " " are treated as a phrase. Conducting a search for "heat model" will return all results in which the exact phrase "heat model" is found, while "heat modeling" would NOT be included.
A term combined with a phrase will be joined with an OR operator.
Searching for Standards
When searching for a standard please use the entire Document Number assigned, which includes the abbreviation. A space can be used, or omitted between the abbreviation and number.
