Noise Studies

Institute of Railway Technology is capable of conducting comprehensive studies in railway related noise including identifying potential noise sources, measuring noise levels, establishing the propagation characteristics of emitted noise, developing noise propagation models, identifying noise reduction measures and providing possible noise reduction programs.

Achievements

• Quantification of noise levels associated with wheel/rail interaction including wheel flanging and rail corrugation.

• Establishment of noise propagation characteristics for rolling stock under different operating conditions.

• Identification of potential noise reduction measures and assisting the implementation of noise reduction programs to maintain noise emissions at reduced and controllable levels.

• Development of a rolling stock noise propagation model to simulate the resultant noise impacts from selected noise source combinations and to calculate the noise level at nominated distances from the track.
