Selecting Calculation Standards

The desired calculation method for industry, road and railway noise can be selected from the drop-down menus at Calculation|Configuration, tab „Standards“. The choice available depends on the standards purchased.

Standards and guidelines, however, do not describe all possible situations or scenarios, so that the range of application being covered originally had to be extended in many cases.

• In all cases the user of the software is responsible for the interpretation and results of the calculation and analysis. We do not take liability for false calculation results and their consequences caused by improper input data and system configuration.
• When switching calculation standards, not all data or values can be adapted afterwards automatically with source parameters having been entered prior to calculation. In any case, the user must check and adapt the data accordingly. For example, selecting the German standards for railway noise using their train classes to evaluate the emission level will produce wrong emission levels when switching to the French standard as in France not the same train classes and corrections apply.

Test Cases

The correct calculation can be proven by official test cases. These are unambiguously described situations published by authorized institutions.
