Measurement methodology of stationary vehicle noise has been developed for utilization in the engineering evaluation of the sound pressure level performance of road vehicles in the vicinity of the exhaust systems. The purpose of this method is to check the vehicles that are in use and determine changes in noise level of exhaust system occurred due to wear and modification of certain components of the exhaust system or removing devices that are used for noise reduction. Basic requirements relating to measuring instruments, measurement conditions and measurment methodology of stationary vehicle noise are presented in this paper. Masurement procedure was demonstrated by measuring the stacionary noise of vehicles of L i M category (two passenger cars and one motorcycle) using two different instruments, with the aim to indicate the possible uncertainty. Same vehicles have been tested on three tehnical inspection stations. Author's intention is to point out the failures that are happening when stationary vehicle noise is measured within the regular roadworthiness test in Bosnia and Herzegovina.
