Description

This sound pressure level measurement procedure has been developed for use in the engineering evaluation of the sound pressure level performance of road vehicles in the vicinity of the exhaust systems. The method is intended to check vehicles in use and also to determine variations in the exhaust sound pressure level that can result from — the wear, maladjustment or modification of particular components, when the defect does not appear by visual inspection; — the partial or complete removal of devices increasing the emission of certain sound pressure levels. It is possible to determine some of these variations by comparing the measurements with reference measurements made under similar conditions, for example during the type approval of the vehicle, using the same method. Other variations can be detected only when the engine is operated at a realistic load. The document incorporates certain provisions of SAE J1492:2008-10 for measuring the sound pressure levels of exhaust systems of passenger cars and light trucks.
