Railway applications. Track. Noise barriers and related devices acting on airborne sound propagation. Non-acoustic performance - Mechanical performance under dynamic loadings caused by passing trains. Calculation methodWhat is BS EN 16727 2 2 Mechanical performance of noise barriers caused by passing trains about? BS EN 16727 2 2 defines the loading, the relevant load model positions, and the internal forces acting on noise barriers, due to the air pressure wave set out in BS EN 1991 2: 2003. The calculation method described in BS EN 16727 2 2 has been developed for noise barriers having a post and panel structure with piled foundations. BS EN 16727 2 2 can also be
