st184 sillycar Forums Junkie Location: Melbourne Registered: June 2004	Re: Defected but not, Police prove their uselessness once again! Sat, 16 April 2005 02:50 I thought it was like this (from APS website) : Exhaust Noise Testing Many statutory bodies around the world currently mandate that vehicles comply with stationary exhaust noise tests specifications - Generally based upon the "SAE J1169 Measurement of Light Vehicle Exhaust Sound Level under Stationary Conditions" For example, California and various other states in the US mandate J1169 SAE stationary noise tests. In Australia the test requirements are ADR 28/01 stationary noise test and it too is based upon SAE J1169. In fact, the above tests have identical test procedures and only the required limit varies: USA . . . . . . 95 dB Australia . . . 90 dB The test involves positioning a type 1, SIA compliant ANSI S1.4 - 1983 noise level meter, specifically as illustrated in the diagram below. No other positioning is relevant! Noise tests are extremely specific in their scope and must be conducted very carefully! Diagram from SAEJ1169 Testing Procedures Engine RPM must be held steady at 75% of rated peak horsepower RPM. Given the latter figure is 6,000 RPM for the US spec. WRX/STI, the test speed is 4,500 RPM for these vehicles. Again, it must be emphasised, all facets of a noise test must be specifically followed for the test to have any meaning.
