About
Dr Felix Langfeldt is Associate Professor and Doctoral Programme Director within the Institute of Sound and Vibration Research, which is part of the Faculty of Engineering and Physical Sciences at the University of Southampton. One of the major focal points of Felix's research is developing new so-called acoustic metamaterials for making transport systems more comfortable, living spaces quieter, and, in general, reducing the problem of low-frequency noise in our environment.

Research interests
- Active/Passive Acoustic Metamaterials
- Low-frequency Sound Insulation
- Aircraft Cabin Noise Control
- Vibro-acoustics of Lightweight Structures
- Analytical Modelling of Multi-layered Partitions
Current research
My current research activities revolve around the development, optimization, and modelling of novel structures that control sound. In particular, my research focuses on controlling noise in challenging acoustic environments, for example low-frequency tonal noise or when constraints in terms of the weight and bulk size of acoustic treatments are present. This has strong applications in aerospace, which has been the background for most of my research in the past, but also in many other areas where tonal noise is present, e.g. cars and trains, home appliances, centrifugal compressors, heat pumps, or ventilation systems.

Biography
Felix Langfeldt studied Aeronautical Engineering (MSc in 2012) and gained more than 10 years of research experience in acoustics and vibration control as a researcher at Hamburg University of Applied Sciences, Germany. He obtained his PhD in 2018 for his work on "Membrane-type acoustic metamaterials for aircraft noise shields" and throughout his career he collaborated closely with other research institutes as well as industrial partners like Airbus or 3M to develop innovative acoustic treatments (with particular focus on acoustic metamaterials) that can be used in aircraft cabins to reduce low-frequency tonal noise. In September 2021 he joined the Institute of Sound & Vibration Research in Southampton as a Visiting Academic, funded by an independent fellowship from the German Research Council. In March 2022, Felix was appointed Lecturer at the ISVR, Signal Processing, Audio and Hearing Group. Since October 2023, he is also the ISVR's Doctoral Programme Director. Felix was promoted to Associate Professor in August 2024.
