Anyone traveling by train through a soundproof corridor is often looking at a green wall. The fact that sound barriers have so far been more impressive in their function than in their beauty is due to physical reasons: Transparent materials are generally not absorbent and, in turn, common acoustic insulation materials are not transparent. For this reason, a project consortium with the participation of Novicos was commissioned by the German Center for Rail Traffic Research at the Federal Railway Authority to test transparent sound insulation concepts for their suitability in an independent expert report.
The result: the fusion of these two properties is possible. Effective, for example, are concepts in which acoustically effective interior spaces are created using multilayer, perforated wall designs.
Further contents of the expert opinion:
Testing of existing concepts for their acoustic performance
geometrical influences of the walls such as their shape, height and mounting angle
Optimization suggestions and ideas for improved prototypes
For this purpose, not only well-known methods for sound calculation such as the BEM (Boundary Element Method) were used. In the end, Novicos' own software developments especially for this discipline enabled a particularly high quality of the results.
In the report of the German Center for Rail Transport Research you will find the complete report with information on our methods and the results.
Curious?
We are commissioned as a scientific development partner or expert when the client depends on outstanding quality and feasibility of the results. Describe your acoustic challenge to us and we will give you feedback on how to solve it.
