Welcome to PreNoise®

- Predicting noise from service equipment in buildings -

PreNoise® allows you to predict noise levels of service equipment in buildings, based on the standards of DIN EN 12354-5. It provides an early-stage approximation of the planned object and allows you to quickly select suitable systems with the required noise protection level in the planning phase and helps to assess the impact of changes to the building's structure.

Start PreNoise light for wastewater systems.

PreNoise® is developed by the Building Acoustics Group at the Fraunhofer-Institute for Building Physics IBP in Stuttgart. To learn more about the app and our services, please read ABOUT THIS APP or the FAQ and visit our website or CONTACT us directly.

How it works...

Upload a PreNoise® Data Package

The PreNoise® Data Package (PDP) is a comprehensive database with complete datasets for various sources. These include airborne sound power levels, single equivalent blocked force levels, single equivalent free velocity levels and the magnitude of single equivalent source mobility, all presented in third-octave bands ranging from 50 Hz to 5000 Hz. The PDP also contains all important information about the sources (name, mounting details, manufacturer, etc.). If a PDP is not available, feel free to try the demo mode.

Choose the calculation model and customize the building elements and rooms according to your needs

In future releases, different PreNoise® versions will be available. Some PreNoise® light versions are designed for very quick and easy predictions for particular installations. The arrangement of the rooms is based on a representative section of an apartment building. This section includes four rooms, two on each floor, separated by an installation wall. Each version of PreNoise® will offer special solutions and features. If your project requires more detailed calculations using the advanced version of PreNoise®, please contact our team for further assistance.

Use the predicted values for planning/comparison

The result of a prediction with PreNoise® is a single number quantity (SNQ), which can be directly compared with regulatory requirements or further calculations. This enables more accurate predictions than relying on comparative values provided in test reports, thereby avoiding later construction defects or unnecessary expensive noise protection solutions.
