Option BPL - Backtracing of Sound Power Levels
Option BPL is very useful in calibrating area sources of which the pressure level at distinct receiver points is known or has been measured, while the sound power level (SPL) or the SPL per unit area is unknown. Option BPL can even handle situations with several area sources and receiver points by applying a user-definable optimization strategy.
Option BPL is also used to fulfill the requirements according to German law when planning industrial or commercial areas. Legally, the sound radiating from different areas must be optimized in such way that the limiting values at all receiver points are not exceeded. The procedure of distributing noise emission for all area sources, with respect to the limits, is known as "Fixing of Noise Quota" (Lärmkontingentierung).
Option BPL optimizes the noise emission in the most favorable way. In CadnaA a specific source type called "optimizable source" offers a flexible approach without restricting the user to a fixed predefined optimization strategy. To achieve this a "usability function" is defined for each area source.
Features
- Automatic or manual optimization of noise emission
- The sound propagation by the "optimizable source" is equivalent to an area source, with respect to segmentation with or without screening
- The screening effect by objects inside the optimizable source can be deactivated with regard to ist own emission
- Switching of the evaluation period day/night
- Input of LWA or LWA" alternatively
- Specific usability function for each area
- Noise emission restricted by MIN and MAX values
