REVIEW OF THE SILENT ROAD TRAFFIC RESEARCH PROGRAM

This article outlines research carried out in noise reduction measures for the German road network. A reduction in tyre noise was achieved by covering the rear wheel arch of a passenger car and coating the interior of the wheel housing with noise absorbing foam. However, it is pointed out that these optimisations are extreme measures and not commercially viable in production. Passenger car tyres were tested on five different surfaces, and results showed that sound-pressure levels determined on standard roadway were not transferable to other road surfaces, although some noise reductions might be possible. A comprehensive test program was carried out on retreaded tyres to determine whether these should be included in new tyre noise legislation: it was decided this would not be meaningful. It was found possible to improve noise emissions on asphalt roads and new methods of measuring roadway characteristics were developed.
