Noise Control and Vehicle Acoustics

Acoustic optimization of technical systems, devices and vehicles

Our experts in the working group “Noise Control and Vehicle Acoustics” focus their activities on the acoustic characterization and further development of technical installations (in buildings), devices, vehicles, and acoustic test laboratories. To develop innovative methods and solutions, we implement a wide range of measuring systems, as well as design and simulation tools.

The main focus of our research is on the development of innovative noise control concepts, and also on systems and devices optimized in terms of acoustics and energy requirements. Our scientific work often extends beyond issues purely related to noise control, right up to the fields of vehicle construction and the machinery and equipment industry, also taking into account aspects such as fluid dynamics, materials science and control technology.

A core area of expertise is the development of silencers, used to solve low-frequency noise problems as well as other particularly demanding applications. The spectrum ranges from sturdy, cleanable duct silencers to sound-absorbing internal flues for chimneys and highly-integrated strip absorbers for boilers.

We also have a modern testing center for vehicle acoustics at our disposal, which enables us to offer the automotive industry a wide variety of development services. Over the years, vehicle acoustics has developed into one of our specialist areas.

Flow noise and flow dynamics

In many technical applications, flow noise is the principle source of noise. Through experiments and numerical CFD and CAA simulations, we investigate flow-induced noise in order to identify ways to reduce it and to optimize products.
