- The research project FH-IPTOOLS is a joint project between Rosenheim Technincal University of Applied Sciences (THRo) and the University of Applied Sciences Döpfer (HSD) in collaboration with industrial partners and timber construction associations. The aim is to develop prediction tools for sound insulation, focusing on acoustic comfort and the perception of noise from technical service equipment. The project focuses on wastewater systems in timber and lightweight constructions.
Concepts need to be developed to ensure that acoustic comfort is taken into account in the design process. HSD is working on the psychoacoustic aspects. Signal detection theory will be used to formulate suitable evaluation methods to assess noise from building service equipment. Listening tests and field measurements will be used to develop criteria for sound insulation in timber construction to improve acoustic comfort.
As part of the project, structure-borne sound characterisation will be carried out at THRo on a reception plate test rig. Therefore a reception plate with similar properties to timber frame constructions will be used. The aim is to develop methods for the direct measurement of structure-borne sound power in timber and lightweight constructions, while also determining airborne sound power. Initial results will be presented in the paper.
