THE CURRENT STATUS OF MEASUREMENT AND EVALUATION TECHNIQUE FOR STRUCTURE-BORNE SOUND MEASURED AT THE TRACK

This paper described the investigation which has led to the suppression of noise pollution produced by rail transport systems. A common noise problem for subway systems lies in the production of structure-borne sound in structures erected in the vicinity of the tunnel. Suppression of noise transmission begins at the point of origin of structure- borne sound, i.e., at the railroad track. The problem for the track engineer is thus one of developing track types with maximum sound-insulation properties. Dr. Steinbeisser described a solution proposed, and the methods and instrumentation utilized, in a tunnel of the S-Bahn (rapid transit system) in Frankfurt. Insulating effects were based upon the insertion of a buffer mass between the floor of the tunnel and the vehicle. It was indicated that great influence can be exerted on the suppression of structure-borne sound by structural measures. The paper discussed the tools of measurement technology which provide a comparison of various track structures with regard to their sound insulating properties.
