Lecture: The effect of close proximity, low height noise barriers on railway noise

Author(s): Nieuwenhuizen Edwin, Yntema Nils

In order to control railway noise in the Netherlands, there is a need to expand the standard set of noise reducing measures. An idea from the old box is to construct small barriers at a very close distance from the track. Issues with regard to safety and maintainability of the track have always been a serious obstacle for building these objects. To overcome these restraints mini barriers were constructed as a pilot project in Hilversum. As part of the evaluation process, the noise reduction of the close proximity barriers was established by measurements. The results were compared with calculations according to the Dutch calculation scheme for conventional barriers.\nThe research shows that the measured overall noise reduction corresponds well to the calculations. Although more work has to be done, it is expected that only minor changes have to be implemented in noise legislation.\n
