Project Kick-off: SWOISE – UAS Swarms for Noise Reduction

15. Juli 2025 | von

Unmanned aerial systems (UAS), such as drones, are becoming increasingly popular for wide range of applications, ranging from delivery and mapping to surveillance. The emergence of the UAS swarm systems, where multiple UAS operate in coordinated formations, might offer advantages regarding improved efficiency and reduced logistical effort. However, UAS swarms also raise concerns about noise pollution, especially in urban environments. The SWOISE project aims to address this issue by investigating the noise generated by drone swarms, how it is perceived by humans, and how swarm configurations can be optimized to minimize acoustic impact. Within the project, the task of IHTA is to focus on the psychoacoustic analysis of UAS swarm noise by creating binaural sound samples using simulations of urban overflights, and analyzing them through perceptual and objective evaluations. This research will be mostly carried out by our post doctoral researcher Jithin Thilakan, who recently joined our team.

SWOISE is funded by the German aviation research program LuFo VI-3 and brings together four research partners:

The project officially launched with a kick-off meeting on July 8th, 2025, at TU Hamburg, where researchers from all partner institutions gathered to discuss the research plans and future steps. We look forward to advancing this collaborative effort and contributing towards quieter and more environment-friendly aviation.

Research results on acoustic directivity patterns of road-traffic vehicles

07. Mai 2025 | von

In the Journal of the Acoustical Society of America (JASA), a research paper by our former research assistant Christian Dreier and Prof. Michael Vorländer was recently published: Speed-dependent directivity patterns of road-traffic vehicles.

This paper explores the spatial and speed-dependent directivity patterns of various road-traffic vehicles, including electric, hybrid, and combustion-powered models. By employing time-variant wave backpropagation on microphone array signals, the research reveals significant insights into how driving conditions and engine characteristics influence vehicle noise emissions. The findings are compiled in an open-access database (http://doi.org/10.5281/zenodo.14142914), providing valuable data for noise mapping and auralization applications. The main parts of this research was supported by the HEAD-Genuit Foundation.

More details of Christian’s research will also be presented at his PhD defense, which will take place end of July 2025.

We’re happy that one of the paper’s figure was also chosen to be featured on the title page of the JASA’s current issue.

Paper published: Cross-modal congruency modulates evidence accumulation, not decision thresholds

25. März 2025 | von

We are happy to announce that our paper „Cross-modal congruency modulates evidence accumulation, not decision thresholds“ was published as part of the Research Topic „Crossing Sensory Boundaries: Multisensory Perception Through the Lens of Audition“ in Frontiers in Neuroscience.

In this study, we collaborated with Björn Kampa from the Systems Neurophysiology Department of the Institute of Zoology here at RWTH Aachen University, and Christoph Kayser from the Department of Cognitive Neuroscience at Universität Bielefeld. We explored how audio-visual stimulus pairs—linked either by co-occurrence or by shared meaning—affect behavior and brain activity during decision-making.

By combining behavioral data from a decision-making task with brain activity measured via electroencephalography (EEG), we found two key stages that shape perceptual decisions: an early, sensory-driven stage, and a later, decision-related stage. Interestingly, whether the stimulus pairing was expected in terms of co-occurrence or meaning played a major role in how these early and late components contributed to the decision-making process.

Paper published: Activity-based acoustic situations in primary schools

21. März 2025 | von

We are happy to share a new publication by Julia Seitz and Janina Fels. Their journal paper „Activity-based acoustic situations in primary schools: Analyzing classroom noise and listening effort“ was published in the Journal of the Acoustical Society of America.

The publication introduces the concept of „activity-based acoustic situations“ in primary schools, shedding light on the everyday sound environment in classrooms.
Key findings include that different classroom activities result in significantly different noise levels, that noise levels decrease as students age—first graders experience higher levels than fourth graders—and that subjective listening effort does not differ significantly between activities. The results highlight the importance of activity-based assessment of classroom noise to create optimal learning environments.

Paper published: Listening effort in children and adults in classroom noise

08. November 2024 | von

We are happy to share the publication of our journal paper „Listening effort in children and adults in classroom noise“ in Scientific Reports as part of the Auditory processing and perception collection!

Julia Seitz, Karin Loh, and Janina Fels conducted a study to investigate listening effort in children aged 6-10 years and young adults using a child-appropriate dual-task paradigm. Realistic classroom scenarios with multi-talker babble noise at different signal-to-noise ratios in anechoic and simulated classroom environments were investigated.

The key findings
• Found differences in listening effort between noise conditions in 8-10-year-olds
• Demonstrated the importance of considering room effects in listening experiments
• Observed correlations between subjective and behavioral measures of listening effort
This research contributes to our understanding of how children process speech in noisy classroom environments and could help to improve learning conditions.

New exhibition DEAR ARCHITECTS: SOUND MATTERS

29. November 2023 | von

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

International Conference on Auditorium Acoustics 2023 in Athens

17. November 2023 | von

From September 28th to 30th, the Institute of Acoustics has held the 11th International Conference on Auditorium Acoustics at the Stavros Niarchos Foundation Cultural Center (SNFCC) in Athens, Greece. Jonas Heck and Josep Llorca-Bofí as well as our alumnus Ingo Witew presented their research in the field of concert halls and room acoustics:

  • Jonas Heck, Josep Llorca-Bofí and Michael Vorländer: Concert Halls in Virtual Reality – From Audio-visual Perception to a Common Vocabulary
  • Ingo Witew and Michael Vorländer: Measurements in room acoustics – How good are we at it?

On the first conference day, Jonas Heck and Josep Llorca-Bofí organized a round table to discuss the importance of descriptive vocabulary which can be used to depict the perception in concert halls. The poster „Concert Halls in Virtual Reality – From Audio-visual Perception to a Common Vocabulary“ was accompanied by a demonstration of a recent experiment in virtual reality. It was very well received by the delegates who selected it for the first poster prize.
