SoundPLAN Noise Barrier Optimization Module
The SoundPLAN Wall Design Module sets a new benchmark for the optimization of noise barriers and berms. In addition to the cost & surface optimization, SoundPLAN visu- alize the geometry and the acoustical model parameters.
The Wall Design Module helps to design and optimized noise barrier along road, railroads, industrial or leisure facilities. It helps to document and visualize the benefits (i.e., noise reduction, compliance with target level) and the pitfalls of barriers (i.e., the barrier height, the barrier length, openings in the barrier, the receiver height or the source height).
From experience it is obvious to the acoustical consultants that the cost vs. noise reduction breakpoint changes drama- tically when for example the maximum height of a noise barrier is lowered. [Note: The maximum height of a barrier may be set by planning constraints or the visual impact.]
What are the principal steps to optimize a noise barrier in SoundPLAN (see Graphic above)? The schematic shows the data flow (Model geometry > Calculation > Wall Design > Results saved to Model). The detailed steps are as follows:
