Paper published: Listening effort in children and adults in classroom noise
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.
Acoustic investigations at Sagrada Familia
At the end of February this year, a team of the Institute for Hearing Technology and Acoustics conducted acoustic measurements at the renown Basílica de la Sagrada Família in Barcelona. The team of experienced acousticians consisted of current and former employees of IHTA and was led by Josep Llorca-Bofí and Michael Vorländer.
In the further course of the project, the measurement data was evaluated, processed and auralizations were generated. The study revealed Gaudi’s design challenges and opportunities and is a basis for future musical instruments design in different places and its liturgical use of the Sagrada Família Foundation.

New exhibition DEAR ARCHITECTS: SOUND MATTERS
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
Contact person: Josep Llorca-Bofí, josep.llorca@akustik.rwth-aachen.de

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).
