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.

BASH 2021 – Joint Conference on Binaural and Spatial Hearing
The 2nd joint conference on binaural and spatial hearing (BASH) was held on October 7th and 8th, 2021. The meeting took place virtually, featuring talks on behavior, modeling, physiology and virtual reality. On Friday, October 8th, Janina Fels and Carolin Reimers gave a presentation on a paradigm investigating auditory selective attention in a virtual classroom, which has been developed in the context of the project “Evaluating cognitive performance in classroom scenarios using audiovisual virtual reality – ECoClass-VR” . This project is part of the priority program SPP2236 – AUDICTIVE: Auditory Cognition in interactive virtual Environments funded by the Deutsche Forschungsgemeinschaft (DFG) – German Research Foundation. Next to exciting projects, AUDICTIVE also organizes workshops for the participating researchers, such as a visualization workshop offered by Martina Grigoleit, which has already been made use of during the BASH.
