junge DEGA Herbstworkshop 2024 in Leipzig & Mittweida
From 24 to 27 October, the “junge DEGA Herbstworkshop” (autumn workshop) took place in Leipzig and Mittweida, with the participation of two IHTA staff members and three students.
Junge DEGA is a section of the German Acoustical Society (DEGA) and partner of the Young Acousticians Network (YAN) of the European Acoustics Association (EAA). Its mission is to connect students, PhDs and young professionals in the domain of acoustics. The group organizes special sessions and panel discussions during the Annual German Conference on Acoustics (DAGA), providing information on research opportunities and job entry. Furthermore, junge DEGA offers a mentoring program with active participation from industry and academia.
On Friday morning, the program started at the Neurobiology Department at Leipzig University, where two experimental setups from the field of neuroacoustics could be viewed and tested. The first experiment was dedicated to auditory distance perception, the second experiment was set up in an anechoic chamber and examined the localization of sound sources using a loudspeaker array. Afterwards, SINUS Messtechnik organized a workshop on measuring sound intensity. This was followed in the afternoon by a guided tour of the Gewandhaus Leipzig, which focused on the history of the building and the orchestra. The day concluded with a visit to a concert by the Gewandhaus Orchestra.
On Saturday, the program continued in Mittweida with a visit of the media center at Mittweida University of Applied Sciences. The participants gained insights into the recording and mixing studios, the acoustics laboratories and the university’s radio station 99drei. This was followed by a workshop on wiki.audio, an open platform on which volunteers contribute their expertise on audio and acoustics topics. In this workshop, the participants wrote their own articles and developed concepts for cross-linking and further enhancing the content, for example through educational walks or the integration of external resources such as the interactive Comsol apps from the Technical University of Munich (https://apps.vib.ed.tum.de). The day’s last activity was a visit to the Mittweida town church, where the participants had the opportunity to see how an organ looks from the inside.
On Sunday, we enjoyed brunch together during a chat with Annika Neidhardt about her career path and current developments in acoustics. To conclude the weekend, we had a group meeting of the junge DEGA section where we discussed a revision of internal guidelines as well as planned activities during the DAS/DAGA conference 2025 in Copenhagen

In particular, our Junior Principal Investigator Dr. Josep Llorca-Bofí, from the PAAD group was invited as key-note speaker, talking about The city – A machine for noise? Virtual acoustics in architectural design research. Together with our PhD student M. Sc. Jonas Heck and Professor Michael Vorländer, the following research paper was presented: 3D photogrammetry for auralization – An approach for geometry simplification and material categorization.

junge DEGA Workshop 2022 in Stuttgart
From 2nd to 4th September 2022, after a three-years break due to the Covid-19 pandemic, the “junge DEGA Herbstworkshop” took place in Stuttgart, like the DAGA conference earlier this year. Junge DEGA is a sub-group of the German Acoustical Society with the mission to connect students, PhDs and young professionals in the domain of acoustics. It organizes special sessions and panel discussions during the Annual German Conference on Acoustics (DAGA), providing information on research funding opportunities and job entry. Furthermore, junge DEGA offers a mentoring program with active participation from industry and academia.
Two PhD students of the Institute for Hearing Technology and Acoustics, Simon Kersten and Jonas Heck, as well as Nils Rummler, recently graduated bachelor student, participated in this year’s workshop. The program started with visits at the Fraunhofer Institute for Building Physics IBP and the Center for Building Physics (ZfB, Hochschule für Technik Stuttgart). Furthermore, it consisted of short presentations given by the participants, a plenary meeting of the junge DEGA group to plan the following year’s activities and a guided visit of the new main station construction site (known as Stuttgart 21) with a focus on noise and vibration control. The weekend was concluded with a hands-on workshop on building a loudspeaker from residual materials and competing for the highest sound pressure level.
Pictures from the workshop can be found in the gallery below.
