Frequently Asked Question
What does PreNoise® mean?
PreNoise® stands for the prediction of noise emissions from service equipment in buildings.
Why "light"?
PreNoise® light is a simplified version designed for very fast and easy changes in a four-room model to predict the sound pressure level in a receiving room located behind an installation wall. It is possible to change the main properties such as material and thickness of the installation wall, where a waste water system is installed, as well as the dimensions of the rooms. For more detailed calculations in the advanced version of PreNoise®, please contact our team.
Who can use this app?
This web app is a test type/prototype currently under research, which can be used free of charge with research results from Fraunhofer IBP.
PreNoise® light is designed for manufacturers and (acoustic) planers for wastewater systems in buildings. Anyone who has access to the source data of a wastewater system measured by Fraunhofer IBP can use this app.

Where can I obtain the source data?
For every measurement of a wastewater system conducted according to DIN EN 14366-1 at Fraunhofer IBP in Stuttgart, you will receive a coded file alongside the test report upon request. To contact to the Building Acoustics Team, please refer to the CONTACT section.
Fraunhofer IBP is not allowed to share source data from any client without explicit permission. However manufacturers/clients can grant permission for their data to be stored in a freely accessible database or share the source data if desired.

What is the advantage of using this app?
The advantage of a prediction with PreNoise® light lies in the fact that it provides an early-stage approximation of the acoustic performance of the planned object, thus allowing for the selection of a suitable wastewater system with the required noise protection level already in the planning phase. This enables more accurate predictions compared to the comparative values provided in test reports, thereby avoiding later construction defects or unnecessary and expensive noise protection solutions.
