TGA Schall: Sustainable sound insulation of technical building systems in energy-optimized buildings

Project background

The aim of the project is to analyze the noise of technical building systems with particular their structure-borne noise characteristics from the source via the transmission transmission in the building to the point of impact. can be described. The methods are to be used by system manufacturers to characterize the sound the sound sources and their acoustic optimization and should be used by building and should be used by building planners as a forecasting tool for sound be used by building planners as a forecasting tool for acoustic planning and design.

Project objective

The aim of the project is to develop coordinated measurement and prediction methods for structure-borne sound generation and sound transmission of building services systems in timber and lightweight construction, validate them and make them available to users. make available to users.

Innovation

In many cases, technical building systems are primarily sources of structure-borne structure-borne sound sources, whose physical description is much more complicated due to interactions between sources and receiving structures is much more complicated than that of than that of airborne sound sources. In addition, the generation and transmission of structure-borne -transmission in solid construction is completely different to that in timber and lightweight construction. lightweight construction. This requires a separate consideration of the excitation and transmission mechanisms for timber construction, which is not yet available in this form. not yet available in this form.
