In order to limit road traffic noise it is necessary to reduce all major sources of the noise. Up to now, all noise emission limits have been based on procedures where the vehicles accelerate from a low speed. This method highlights the noise emitted from the power-train units of the vehicles. To obtain any further noise reduction it is necessary to introduce also limits for tire/road noise and noise influences by road surfaces (simply speaking to eliminate tires and surfaces which are excessively noisy). As an important step in this direction, there is a work item of the Internatioal Organization for Standardization (ISO) which is focused on measurement methods for comparison of noise on different road surfaces. One of the methods considered by the group working on this subject is the trailer method which is reviewed in the report. Nine trailers used for tire/road noise measurements have been reviewed. Two of them have been used for testing of truck tires and the remaining seven have been intended for passenger car tires. All of them would be possible to use also for testing road surfaces. The review includes the most important technical data of the trailers as well as the microphone positions used during the measurements.
