Facade Noise Map

The Facade Noise Map is the second most popular noise mapping option, following the Grid Noise Map. The Facade Noise Map generates receivers along all marked facades of all buildings. The Graphics can display the results in various forms, including 2D and 3D displays.

In the GeoDatabase, mark the facades for computing the noise levels. To do this, either mark all buildings and include all facades, or click on each building and mark the facades to be included. The buildings already contain information about the number of floors (from the data entry when generating the model), so SoundPLAN has the necessary information to calculate receivers for each floor.

Facade noise calculations are defined in the spreadsheet of the calculation core, and thus can be run stand alone, as a batch, or distributed on multiple computers. The results of the calculation are available in Documentation, Spreadsheet, Wall Design and Graphics modules. Opening the data in the Spreadsheet allows a much more detailed analysis of the noise situation than trying to extrapolate the exposure from grid noise maps calculated 4 meters above the ground in the vicinity of the buildings. In the Spreadsheet, residents can be distributed on a square meter basis or directly assigned to a facade length where the direct connection to the calculated noise levels can be made.

The following graphic shows how different the presentation of the same facade noise map can be. The same file was opened 6 times with different settings. Tiles c, e and f depict information from the City Noise Map, which is organized internally like a Facade Noise Map. If the Grid Noise Map and the Facade Noise Map are part of a SoundPLAN license, City Noise Map is automatically included.

There are many formatting options to customize the appearance of the Facade Noise Map, as can be seen in the following pictures.

When combined with the 3D solid modeling, the Facade Noise Map can show the floors on a high-rise building where noise protection windows are needed.
