Sound has many facets. We encounter it in many different ways in our daily lives. As a language, it is a basis for communication. It is not only in the form of music that sound can create intense, often positive emotional states. But sound can also be annoying, disruptive and even hazardous to health - especially in societies characterized by increasing mechanization and urbanization. Technical acoustics in engineering deals in particular with the issues arising from the latter point: Which technical solutions are particularly quiet? How can low-noise construction be achieved? What noise reduction measures are possible?
With Acoustic Engineering, we strive for intrinsic acoustic design in the early phases of product development. One of our research focuses is the integration of acoustic functions into new products and systems. The main focus is on low-noise design with noise reduction measures, such as intelligent structural modifications and innovative passive damping measures. With the help of suitable acoustic models, efficient simulations and experiments, an optimal acoustic design can be found.
With Computational Acoustics we investigate wave-resolving numerical methods for vibroacoustic models and develop our own research code elPaSo (ELementary PArallel SOlver). Our main goal is to provide robust solutions for coupled airborne and structure-borne sound domains. Important topics are the quantification of sensitivities, model order reduction techniques, hybrid methods and sustainable code development.
With Models & Systems we create descriptions for acoustic systems using adequate and robust modeling techniques. One focus is on the application of machine learning algorithms to derive models based on observed data. Another focus in the context of modeling acoustic systems is the area of noise assessment, as it enables model confirmation and provides information for improving systems with the aim of a quieter future.
