junge DEGA Herbstworkshop 2023 in Aachen

20. Dezember 2023 | von

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.

The weekend concluded with a hands-on workshop on binaural synthesis and virtual acoustics applications (see virtualacoustics.org) at IHTA.

Thanks to all participants and supporters!

Equal-Life Symposium in Aachen

How often do you think about sound? How do you want people to feel when you are designing a space? Good acoustics design is inherent to architecture. Every decision you make about shape, form, geometry, volume and materials defines the acoustics. So how do you design proactively for the right outcomes, the first time?

With the comprehensive exhibition DEAR ARCHITECTS: SOUND MATTERS we want to link the field of acoustics more with that of architects. We show how acoustics are integrated into the design process and how auralization and simulation tools make it possible to experience acoustics at an early stage.

The exhibition is organized by the PAAD group in collaboration with the Design Computation chair at the RWTH.

Place: Reiff Foyer of the Faculty of Architecture, RWTH Aachen University, Schinkelstraße 1, 52062 Aachen

Dates: 7-13 December

Finissage: 13th December at 19h

RWTH Schüler*innenuni 2023 at IHTA

06. September 2023 | von

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!

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

27. April 2023 | von

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.
