Proof of usability for noise barriers with laminated safety glass along railway lines
* Presenting author
Abstract:
Noise barriers are the most common measure employed to protect against railway noise in Germany. The construction must satisfy acoustic as well as non-acoustic requirements. Both are decisive in determining the usability of a new product. Acousticians naturally focus on the acoustic requirements. However, it is of equal importance to demonstrate that the non-acoustic requirements are met as well, and this consideration should be Integrated from the start. This paper aims to illustrate this process using laminated safety glass (LSG) as an example. In a project commissioned by the German Centre for Rail Traffic Research, MFPA Leipzig GmbH is developing a procedure for verifying the usability of noise-reducing elements filled with LSG along railway lines. LSG is a material with high transparency and numerous other beneficial properties such as high durability and high chemical and physical resistance. However, the multi-layered structure presents a challenge in terms of proof of usability. The three-year research project is scheduled to conclude in spring 2025. This paper outlines the fundamental work steps and the latest results.
