PAAD: Visual documentation of Berlin Philharmonie
PAAD „Person-focused Acoustics of Architectural Design“ research group has recently visited Berlin Philharmonie to capture 3D data of the auditorium for the MUSKLA Database: a growing collection of narrow angle and spherical photographs of major concert halls in Europe. The goal is to support state of the art multimodal perceptual studies in auditoriums by providing a reference database accessible to the scientific community. In collaboration with our colleagues from Universitat Politècnica de Catalunya and Fraunhofer-Institut für Bauphysik, our team was able to conduct a comprehensive 3D capture of the auditorium.
We documented the auditorium combining imaging techniques to ensure both geometrical accuracy and photorealistic texture:
– 360° panoramic photography to record the spatial impression and visual atmosphere of the hall, located in multiple seating positions from the audience view.
– Narrow angle photo capture to enrich the textures and surface details needed for realistic visualization and to produce accurate photogrammetric model of the hall.

The data collected will become openly available through the MUSKLA database providing researchers and practitioners with resources to create immersive virtual experiences as well as accurate 3D models of major auditoriums.
We thank the staff who welcomed our team and supported a smooth operation throughout the day!
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
International Conference on Auditorium Acoustics 2023 in Athens
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.

IHTA at the BauSIM conference in Weimar
From the 20th to the 22nd September 2022, the BauSIM conference took place. The scientific core topic of the conference is traditionally the energetic simulation in the building sector and offers an ideal discussion forum for experts from science and industry for mutual exchange. The conference is organized by the and IBSPA Germany-Austria, member of the International Building and Performance Simulation Association (IBPSA) This year’s conference introduced a new session on acoustic simulation topics, and our institute was present.
In particular, our Junior Principal Investigator Dr. Josep Llorca-Bofí, from the PAAD group was invited as key-note speaker, talking about The city – A machine for noise? Virtual acoustics in architectural design research. Together with our PhD student M. Sc. Jonas Heck and Professor Michael Vorländer, the following research paper was presented: 3D photogrammetry for auralization – An approach for geometry simplification and material categorization.

DAGA 2021 poster award
At the DAGA Acoustics Annual Conference 2021, one of the poster awards has been given to the work presented by Jonas Heck, Josep Llorca-Bofí and Michael Vorländer, with the title: Hearing Architecture and Seeing Soundscapes: Methodological Approach of Individual Vocabulary Profiling to Evaluate Audiovisual Perception.
Congratulations!
PAADtalks!
PAADtalks! are here: the interdisciplinary colloquium organized by the Person-focused Analysis of Architectural Design – PAAD group in collaboration with the Human Technolgy Center at the RWTH Aachen University. This series of academic lectures gathers humanities and technological approaches to architecture, and constructs collaboration networks for upcoming actions. There is no complete way to approach a person-focused analysis of architecture without an integral view. PAADtalks! spreads architectural research from the broad sense, beyond any reductionism or utopian pretension. More information through this email.
