RWTH Schüler*innenuni 2023 at IHTA
On July 20th, around 20 pupils aged 16 to 18 years, visited IHTA as part of the “Schüler*innenuni” by the Electrical Engineering faculty at RWTH Aachen. In a short introduction, they got insights into what research is conducted at IHTA and which role institutes take over at the university. Afterwards, they took part in four different workshops. They experienced the effect of standing waves, how we hear binaurally, and how the speed of sound and the Doppler effect are connected. Additionally, they built a simple loudspeaker with Lego bricks, aluminium foil, and magnets. To conclude the “Schüler*innenuni” workshop at IHTA, three research assistants presented what they studied and how they afterwards found their way into research. Everybody had a lot of fun experiencing some fundamentals of acoustics, the pupils as well as the assistants!

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!

New publication on HRTFs in Journal of the Audio Engineering Society
We are happy to announce that the article “A magnitude-based parametric model predicting the audibility of HRTF variation” by Shaima’a Doma, Cosima Ermert, and Janina Fels has been recently published in the Journal of the Audio Engineering Society (JAES) as part of the Special Issue on “Spatial Audio”. The study examines just noticeable differences in HRTFs with a focus on monaural cue changes. The probability of a listener detecting spectral changes is modelled as a function of three monaural error metrics, with linear model coefficients derived using Principal Component Analysis.
The open-access article can be viewed and downloaded in the AES E-Library.

Sacred Sound: The acoustic reconstruction of no longer existing spaces
The project Sacred Sound – Sacred Space, led by musicologist Prof. Stefan Morent of the University of Tübingen, deals with the acoustics of sacred spaces as they existed and were used many centuries ago. In cooperation with IHTA, this project uses simulations to reconstruct, for example, the acoustics of the abbey church of Cluny III in order to auralize the liturgical chants of the medieval monks. Cluny III existed between 1130 and 1790 and was the largest church in the world until the construction of St. Peter’s Basilica in Rome.
Based on the room acoustic simulations, medieval choir chants were performed and recorded in IHTA’s laboratories by the ensemble Ordo Virtutum. During the recordings, the singers were presented with the reflections of the virtually reconstructed church space in real time. In further steps of the project these recordings will be analyzed musicologically in order to investigate the influence of the architecture on the musical performance.
Parts of the project were recently documented by the SWR in a radio (116 min.) and a TV report (20 min; both in German language).

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.

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.

This annual event in Czech’s capital city is an excellent opportunity for undergraduate and postgraduate students to gain first experiences at an international conference and strengthens the relationship between CTU Prague and RWTH Aachen University.
Three Phd students of the Institute for Hearing Technology and Acoustics presented scientific work in Prague:
- Anne Heimes: Virtual reality environments for soundscape research
- Carolin Reimers: Investigating the Auditory Selective Attention Switch in Virtual Reality
- Lukas Vollmer: Evaluating Spatial Audio for Hearing Aid Applications
We are happy to report that the work by Anne Heimes was selected by a jury as the best paper in the category Informatics and Cybernetics. Congratulations to Anne for this award!
Pictures of the event can be found on the conference’s website.
Verabschiedung von Herrn Uwe Schlömer
Nach einer fast 50-jährigen Dienstzeit ist am 1. August 2022 der Leiter der mechanischen Werkstatt, Uwe Schlömer, in den wohlverdienten Ruhestand gegangen. Zur Verabschiedung wurde, entsprechend der Tradition der Doktorhüte, diesmal ein „Meisterhut“ überreicht, begleitet von einem Buch mit Grußworten aktueller sowie ehemaliger Mitarbeiter*innen und Anekdoten aus der langjährigen Dienstzeit.
Das IHTA bedankt sich auch an dieser Stelle nochmal für die hervorragende, immer verlässliche Arbeit von Uwe Schlömer und wünscht alles Gute für den Ruhestand.
Die mechanische Werkstatt des Instituts wird nun von Marc Eiker geleitet.
