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

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.

IHTA at the BauSIM conference in Weimar

22. September 2022 | von

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.

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.
