The 27th CEAS-ASC Workshop on “Cabin Noise: Prediction, Testing, Reduction which took place from 20–21 October 2026 brought together experts from academia and industry at the Haus der Wissenschaft in Braunschweig to discuss current challenges and advances in cabin acoustics. The workshop is an instantiation of the annual meeting of the Aeroacoustics Specialists’ Committee of CEAS which focuses on the prediction, measurement and reduction of noise in aircraft, road vehicles and space applications.

This year the event was jointly organised by SynTrac and the German Aerospace Center (DLR), with SynTrac Spokesperson Sabine Langer of Technische Universität Braunschweig and Jan Delfs of DLR serving as workshop chairs.

Cabin noise remains an important challenge in the development of quieter and more comfortable transport systems. In aviation and road vehicles, noise generated by airflow, propulsion systems and structural vibrations can significantly influence passenger comfort and the overall acoustic environment.

The workshop provided a platform for researchers and engineers to exchange knowledge on experimental testing, numerical prediction methods and innovative noise-reduction strategies. Key topics included flow-induced noise, structure-borne sound, electric propulsion, propeller acoustics, psychoacoustics and noise-related challenges in space applications.

By bringing together different areas of expertise, the workshop aimed to strengthen the exchange between fundamental research and practical engineering applications.

The programme also featured contributions from industry representatives, including Stefan Moal of Airbus Aircraft and Michael Hartmann of the Volkswagen Group. Their keynote contributions highlighted the importance of cabin acoustics for comfortable transport systems and provided valuable insights into the approaches of these industry leaders.

The exchange between industrial practitioners and academic researchers is particularly relevant as manufacturers seek to meet increasingly demanding expectations for acoustic comfort while developing new propulsion technologies and more efficient transport systems.

How can new technologies change our everyday lives? And how can complex scientific topics be conveyed in a playful and understandable way? Students explored these and many other questions on October 2 during the new event format “BRAINSTORM – Your Day in Future Mode” at phaeno Wolfsburg.

Students in 8th grade and above were able to experience cutting-edge research firsthand, conduct their own experiments, and engage in conversation with scientists. It became clear that research does not just take place in the lab, it is part of our daily lives and plays a vital role in shaping our future.

As part of the Technical University of Braunschweig’s presentation, SynTrac was also represented with its own hands-on activity and brought the Science Lab’s rowing ergometer to Wolfsburg. This allowed the young people not only to learn about current research in an abstract way but also to get actively involved themselves. By trying things out for themselves, they quickly gained direct access to the scientific topics SynTrac is working on. They were able to experience firsthand the project’s mission, which aims to ensure that aircraft of the future can deliver the same performance with less energy consumption, thereby making global mobility more climate-friendly.

The many questions and discussions on site were particularly engaging. The students shared their own experiences and ideas and wanted to know how our research works and when the new aircraft will take off.

For a research project with strong societal relevance, such as Syntrac, this direct exchange is especially valuable. Not only does this spark interest in the research questions, but it also creates a space to reflect on the importance of basic research for their own futures and to exchange ideas on the topic.

In addition to the Technical University of Braunschweig, many other institutions were involved, including Wolfsburg Hospital, Ostfalia University of Applied Sciences, 42 Wolfsburg, and the Open Hybrid LabFactory.

The diversity of the offerings demonstrated just how differently future-oriented topics can be approached. From food chemistry and sustainable urban development to smart building technology, energy-efficient sensors, and innovative technologies in mechanical engineering, all the way to virtual reality and new learning environments, the young people were able to explore a wide variety of research and application areas.

For students, this type of event offers the chance to discover connections to topics that may initially seem abstract in everyday school life. At the same time, they were able to gain an impression of the wide range of opportunities offered by a degree program or a career in the scientific and technical fields.

For SynTrac, “BRAINSTORM” was therefore a great opportunity to raise awareness of research, engage with a young audience and the students of tomorrow, and demonstrate how scientific work is connected to concrete questions about our future.

We would like to extend our heartfelt thanks to all the organizers and especially the many curious students for the interesting conversations and open dialogue.
