The working group “Building Acoustics” investigates the acoustic properties of building products (building components and building systems). The objective is to optimize the acoustic quality of the complex systems of our customers by means of a targeted development to achieve conditions allowing for an excellent sound protection in the building. The ideal measure of constructional sound insulation is one of the important conditions for sustainable building construction, influencing both comfort and well-being in residential building, and the performance and health in commercial building. On the other hand, there are costs and efforts to be taken into account. Thus, thorough planning and effective execution are the keys to achieving the objective, especially as subsequent improvements of the acoustic properties of a building are usually uneconomically or even impossible.
Furthermore, the building acoustics group carries out sound insulation analyses within the urban building context. Here, again, planning is extremely relevant and presents a particular challenge within the interaction between politics, environment and society.
For the targeted, application-oriented research more than 20 acoustic laboratories and test facilities are available, as well as a multitude of measuring methods.
In order to verify the efficiency of building products, the working group operates an independent accredited test laboratory serving as an interface between research, industry and building practice in the technical fields of work:
