Aachen Acoustics Colloquium 2024

27. November 2024 | von Aspöck, Lukas

Currently the 15^th Aachen Acoustics Colloquium is taking place at Parkhotel Quellenhof in Aachen. This year’s scientific program includes 26 interesting contributions (2 Keynotes, 18 presentations and 6 poster presentations) about current research within the area of automotive acoustics, accompanied by a technical exhibition from various companies and research institutes. A detailed overview of the program can be found in this PDF.

Our institute is part of the organizing team of this event, which is attended by around 190 persons (~170 in-person and 22 online). On Tuesday morning, Michael Vorländer chaired the session „Infotainment in the vehicle“ including a very interesting keynote presentation by Hermann Ney on the current progress in speech and language technology. In the following session about numerical methods and simulations, our research assistant Christian Dreier held a presentation titled „Speed-dependent directivity patterns of road traffic sound sources“.

Additionally at the exhibition, our Institute presented current progress of research projects, e.g., the BalSaM project, in form of interactive demonstrations.

Inter-Noise 2024 in Nantes

10. September 2024 | von Aspöck, Lukas

This year’s Inter-noise conference took place from August 25^th to 29^th in Nantes, France. More than 1500 delegates participated in this conference and presented interesting research in the field of acoustics and noise. Highlights of the conference included a plenary talk by Arnaud Can and Pierre Aumond (Joint Research Unit in Environmental Acoustics at Gustave Eiffel University, Nantes, France) on advanced characterization of urban sound environments and a keynote lecture about the child perspective on noise exposure and health effects, held by Kerstin Persson Waye from Gothenburg University, Sweden, who is also collaborating with IHTA in the Equal-Life project.

Members of IHTA travelled to the conference and presented the following research papers:

Chalotorn Möhlmann: Validation measurement of vehicle pass-by models for dynamic urban environments (results of the BaLSaM project)
Marco Berzborn: Inference of the acoustic properties of transversely isotropic porous materials
Lara Stürenburg: Loudness and preference judgments for noises of a heat pump (results of the LowNoise project)
Joao Fatela (Guest researcher from the University of Campania Luigi Vanvitelli, Naples, Italy):
An experimental setup to investigate relevant validation parameters for the auralization of commercial aircraft flyovers in complex urban contexts

Directly after the closing ceremony of the conference, the satellite workshop “Unlocking the Potential of Open Research Software in Acoustics at Inter-Noise 2024” started. This event was organized by Maarten Hornikx and Huiqing Wang, from the Building Acoustics team of Eindhoven University of Technology, and included interesting exchanges and presentation on the development, maintenance, documentation and distrubtion of acoustics-related open-source software. As one of four invited speakers, Lukas Aspöck held a presentation about IHTA’s auralization software Virtual Acoustics. The slides of this presentation are available for download (CC BY-SA 4.0).

Next to insightful overview presentations by Maarten Hornikx and Huiqing Wang, further successful research software was presented: Pyroomacoustics by Eric Bezzam, NoiseModelling by Pierre Aumond and SoundScapy by Andrew Mitchell, along with many examples of challanges and best practices for open research and open-source software development. Many thanks to Maarten and his team for the invitation and the organization of this exciting event.
