Measurement of Interior Sound Levels of Light Vehicles
J1477
This SAE Recommended Practice establishes the test procedure, environment, instrumentation, and data analyses for comparing interior sound level of passenger cars, multipurpose vehicles, and light trucks having gross vehicle weight rating (GVWR) of 4540 kg (10 000 lb) or less. The test procedure is characterized by having fixed initial conditions (specified initial vehicle speed and gear selection at the starting point on the test site) to obtain vehicle interior sound measurement during road load operation over various road surfaces at specified constant speeds. The measurement data so derived is useful for vehicle engineering development and analysis.
Rationale: The technical committee determines that the using community is moving towards newer technology and would like to alert users that this newer technology exists which may want to be considered for new design. However, because the technical committee has no complete visibility of where and how a technical report is being used, and because a technical report may be necessary to support legacy platforms or design reuse, the technical report should not be cancelled but rather stabilized with a Rationale Statement that alerts users to new technology.
