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.}, language = {en} } @misc{KruseSchoepferSchandaetal.2024, author = {Kruse, Tobias and Sch{\"o}pfer, Fabian and Schanda, Ulrich and Mayr, Andreas R. and Dehm, Maximilian}, title = {Experience with the high mobility reception plate for source characterization according to EN 15657}, series = {INTER-NOISE and NOISE-CON Congress and Conference Proceedings}, journal = {INTER-NOISE and NOISE-CON Congress and Conference Proceedings}, doi = {10.3397/IN_2024_4067}, pages = {8261 -- 8268}, year = {2024}, abstract = {EN 12354-5 describes methods for the prediction of noise from technical equipment based on the airborne sound radiation and the structure-borne sound excitation. This paper considers methods to characterize the source in terms of structure-borne-sound (sbs) emission. Laboratory methods for sbs source characterization are given in EN 15657. In current research and development projects at Rosenheim Technical University of Applied Sciences these methods are applied to fully characterize technical equipment such as heat pumps or ventilation systems. This includes the determination of the equivalent blocked force, the source single equivalent free velocity and the source single equivalent mobility. EN 15657 describes various methods to determine the required properties. Recent project experience showed that this is essentially necessary because the most suitable method has to be applied depending on the nature of the technical equipment.
