Product Description

Subway Vibration Isolation Spring Metro Track Architecture Damping SpringSubway Vibration Isolation Spring Metro Track Architecture Damping SpringSound emission and immission - Noise sources due to railway traffic

Railway vehicles generate rolling noises and vibrations during operation. This is due to roughness and imbalances on both the wheels and the rail running surfaces. Surface defects such as head checks, corrugations and slip waves on the rails are known to be among the most common sources of interference. These vibrations are transmitted to the ground via the roadway and spread as structure-borne noise. If buildings are located along or near the track, a transfer is also carried out via their foundations. The buildings begin to vibrate and, with the appropriate intensity, they are also preceived by humans as perceptible vibration or disturbing noise. Another consequence of this transmission chain is the emission of vibrations from building parts, e. g. ceilings and walls, to the environment. This takes place via the air, which begins to vibrate itself and then become audible as socalled secondary airborne sound.

By isolating the overall vibration of the track through which the train passes and isolating the vibration source, we ensure that the noise in the subway reaches the first-class standard.
