Welcome to PreNoise®

- prediction of noise from service equipment in buildings -

PreNoise® offers you the possibility to predict the noise level of service equipment in buildings based on DIN EN 12354-5. It provides an approximation of the planned object and allows you to select suitable systems with the required noise protection level already in the planning phase of your building or to get an idea of the impact of changes to the building's characteristics.

Start PreNoise light for wastewater systems.

PreNoise® is developed by the building acoustics group at the Fraunhofer-Institute for Building Physics IBP in Stuttgart. If you want to learn more about the app and our services, please read ABOUT THIS APP or the FAQ and visit our website or CONTACT us.

How it works...

Upload a PreNoise® Data Package

The source file or PreNoise® Data Package (PDP) is a database with complete datasets for sources including the airborne sound power level, the single equivalent blocked force level, the single equivalent free velocity level and the magnitude of single equivalent source mobility in third-octave bands from 50 Hz to 5000 Hz. The PDP also contains all important information about the sources (name, test report number, test object number, manufacturer, etc.). If you don't have a PDP, you can try the demo mode.

Choose the calculation model and change the building elements and rooms according your needs

In the future, different PreNoise® versions will be available. Some PreNoise® light versions are for very quick and easy predictions for particular installations. The arrangement of the rooms is based on a section of an apartment building. The section includes four rooms, two on each floor, separated by the installation wall. Every version will have special solutions and opportunities. If you need more detailed calculations in the advanced version of PreNoise®, please contact our team.

Use the predicted values for planning/comparison

The result of a prediction with PreNoise® is a single number quantity (SNQ) for direct comparison with requirements or further calculations. This enables more accurate predictions compared to the comparative values provided in test reports, thereby avoiding later construction defects or unnecessary expensive noise protection solutions.
