Frequently Asked Question
What means PreNoise®?
PreNoise® stands for the prediction of noise from service equipment in buildings.
Why light?
This is a light version for very fast and easy changes in a four room model to predict the sound pressure level in a receiving room behind the installation wall. It is possible to change the main properties (material and thickness) of the installation wall where a waste water system is installed, as well as the size of the rooms. If you need 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 and is currently the subject of research, which can be used free of charge with research results from Fraunhofer IBP.
PreNoise® light is designed for producers and (acoustic) planers for wastewater systems in buildings. Everyone who has the source data of a wastewater system measured by Fraunhofer IBP can use this app.

Where I can get the source data from?
With every measurement of a wastewater system according to DIN EN 14366-1 at Fraunhofer IBP in Stuttgart, you will receive, upon request, a coded file alongside the test report. For contact to the building acoustics team, see CONTACT.
Fraunhofer IBP is not allowed to share the source data from any client without permission, so producers/clients can grant permission to store it in a free available database or share the source data themselves if they want.

What is the advantage of using this app?
The advantage of a prediction with PreNoise® light lies in the fact that it provides an approximation of the planned object, 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 expensive noise protection solutions.
