Project FH-IPTOOLS: Wastewater Noise in Timber Constructions, Prediction and psychoacoustic perspective
* Presenting author
Abstract:
The FH-IPTOOLS research project is a collaboration between the Technical University of Applied Sciences Rosenheim (THRo) and the University of Applied Sciences Döpfer (HSD), in partnership with industry and timber construction associations. The objective is to develop building acoustic prediction tools, with a focus on acoustic comfort and the perception of noise from technical service equipment. The project specifically addresses wastewater systems in timber and lightweight constructions. To integrate acoustic comfort into the design process, new concepts must be developed. HSD is responsible for investigating psychoacoustic aspects, utilizing signal detection theory to establish appropriate evaluation methods for assessing noise from building service systems. Listening tests and field measurements will be conducted to define criteria for sound insulation in timber construction, ultimately enhancing acoustic comfort.As part of the project, structure-borne sound characterization will be performed at THRo using a reception plate test rig. A reception plate with properties comparable to timber stud structures will be employed. The goal is to develop methods for directly measuring structure-borne sound power in timber and lightweight constructions, while also determining airborne sound power.
