junge DEGA Herbstworkshop 2023 in Aachen
From 17th to 19th November 2023, the “junge DEGA Herbstworkshop” (autumn workshop) took place in Aachen. 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.
The workshop started on Friday afternoon with a visit of HEAD Acoustics GmbH in Kohlscheid, where the participants got insights into the company’s research and development activities and experienced some hands-on demonstrations of new products. After this first visit, three RWTH spin-offs – FEV, KLANG, elevear – reported on their experiences in business practice and illustrated different career paths in the field of acoustics. The first day concluded with a meeting of the group resuming the year’s activities and discussing the plans for the upcoming conference DAGA 2024.
On Saturday, the participants visited four laboratories at RWTH Aachen University. The day started with a welcoming tour at the Institute for Hearing Technology and Acoustics (IHTA) with demonstrations of the room acoustics simulation software RAVEN, experiments for audio-visual perception studies and the SCaLAr loudspeaker array. The Institute for Automotive Engineering (ika) opened the doors to their semi-anechoic climate chamber and to a broad range of tire test rigs, which are used to determine the dynamic load during tire-road contact under the influence of different road surfaces. The Experimental Behavioral Psychobiology group & Brain Imaging Facility at RWTH University hospital presented research in which specific acoustic stimuli are used during magnetic resonance imaging to better understand the auditory processing with schizophrenia. Finally, the III. Physics Institute B presented its research on a sonar- and radar-equipped melting probe which aims to penetrate the ice shield and explore the subglacial ocean of the Jovian moon Europa (TRIPLE). Another project focused on the use of acoustic measurements to calibrate the neutrino observatory IceCube.

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!

BaLSaM project at IHTA invites to the kickoff event
The BaLSaM project investigates how traffic noise can be simulated and auralized, aiming to develop concepts to minimize road noise to create more pleasant environments. The goal is to make living spaces more attractive for people. For this purpose, the simulation focuses on the noise perception of humans so that the noise pollution is represented as accurately as possible. This simulation technique will later be used in planning traffic and living spaces. Additionally, an optimization study for exemplary scenarios will also be carried out during the project. If you are interested in this topic, we would like to invite you to the online BaLSaM kickoff event. You can register here: (DE) http://bit.ly/BaLSaMde
BaLSaM is funded within the mFUND framework.
The BaLSAM project partners are:

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.
