This SAE Standard is derived from SAE J2805 and specifies an engineering method for measuring the minimum noise emitted by road vehicles. The specifications reproduce the level of noise which is generated by the principal vehicle noise sources consistent with minimal noise emission in urban traffic. The method is designed to meet the requirements of simplicity as far as they are consistent with reproducibility of results under the operating conditions of the vehicle.
The test method requires an acoustical environment which is only obtained in an extensive open space. Such conditions usually exist during:
• Measurements of vehicles for regulatory certification
• Measurements at the manufacturing stage
• Measurements at official testing stations
Rationale
This Surface Vehicle Standard provides a method to measure the minimum noise emission of road vehicles and external sound generation systems intended for the purpose to provide acoustic information to pedestrians. This standard provides a performance-based and technology neutral test procedure. This standard reflects the development of engine and propulsion technologies which have noise emission characteristics that cannot be correctly tested under existing SAE Standards.
The Safety & Human Factors Steering Committee considers methods for defining, developing, and evaluating human-machine operating characteristics for advanced vehicle systems. Human factors is a cross-cutting discipline that has applications to the design, operation, and evaluation of the human-machine interface elements in vehicle and infrastructure systems. The Steering Committee addresses issues of interface design, driver workload, safety, system complexity, ease of use, and the response of drivers to automatic control systems, especially with regard to risk compensation. The Steering Committee also provides input to the work of ISO TC22 SC39 (Formerly ISO TC22 SC13).Steering committee reporting to MVC
* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.

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.
Wild Cards
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
Using Quotes
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.
