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
Thanks to all participants, organizers and supporters!

2nd IHTA Retreat
On the 23rd and 24th of May 2024, the scientific staff of IHTA was on a retreat at Fährhaus km734 in Düsseldorf. During these two days, the aim was to foster collaboration and exchange between the researchers. Next to an inspiring presentation on personal strengths and interests by the moderator and career coach Bastian Hughes, we helped each other understand individual challenges in more depth by visiting different world cafés. Further, we learned that most researchers face the same obstacles during their careers. Team spirit was challenged during an evening pub quiz and finding solutions for the identified obstacles in team sessions.
Overall, it was two successful days with a lot of input for each individual and a lot of output for the group at IHTA.
A big thank you to Bastian Hughes, who guided us through the two days with his great moderation!

Im Zuge der Zusammenarbeit mit Prof. Stefan Morent von der Universität im Projekt „Sacred Sound – Sacred Space“ demonstrierten unsere Mitarbeitenden Carolin Breuer und Pascal Palenda die Möglichkeiten, Räume akustische zu simulieren und auralisieren, in virtuelle Räume hinzusingen oder zu musizieren, sowie Räume in der Virtuellen Realität mit Hilfe eines Head-Mounted-Displays interaktiv akustisch-visuell erlebbar zu machen.

60 Jahre I(H)TA- Fest
Am Samstag, den 19. August 2023 wurde das 60-jährige Bestehen des IHTA/ITAs gefeiert.
Das Institut für Technische Akustik wurde nach einer Übergangphase ab 1961 offiziell am 2.1.1964 mit Prof. Dr. Wilhelm Janovsky als erstem Leiter gegründet. Es folgten 1972 Prof. Dr. Heinrich Kuttruff, 1996 Prof. Dr. Michael Vorländer und schließlich seit 2020 Prof. Dr.-Ing. Janina Fels als Leitung des heutigen Instituts für Hörtechnik und Akustik.
Über 120 Ehemalige und Aktive des Instituts nahmen an der Feier mit Führungen und Demonstrationen aktueller Forschungsthemen und natürlich am Essen, Getränken und Live-Musik der IHTA-Band teil.
Ein besonderer Dank gilt hier der Gesellschaft für Technische Akustik e.V. (GfTA), die diese Feier ermöglicht hat. Wer noch nicht Mitglied im Verein ist, kann dies hier (Beitrittserklärung) werden, damit wir auch weiterhin das Netzwerk aus Ehemaligen und Aktiven und dem Nachwuchs in der Akustik unterstützen und pflegen können.
1st IHTA Retreat
An interchange for good teamwork between researchers
On 28th and 29th March 2023, the scientific staff of IHTA was on a retreat at Gut Hohenholz near Bedburg in the Rhein Erft Kreis. During these two days, the institute’s past was reflected, and it was discussed how the future of the IHTA can be shaped together. Moreover, there was an intensive exchange among each other’s scientific work in the form of poster sessions. The researchers presented each other’s projects and revealed which milestones needed to be reached to achieve specific goals. Between poster sessions team spirit was strengthened, and the future of teaching and workflows were addressed. Furthermore, it was discussed how the skills of individual researchers could be maintained and passed on to new staff members.
Overall, it was two successful days with a lot of input for each individual and a lot of output for the group at IHTA.
A big thank you to Joachim Bellut, who guided us through the two days with his great moderation!
