According to the funding institution (Deutsche Forschungsgemeinschaft) an ethical approval is not required, since the respective indications do not apply [125]. The study was conducted under the ethical principles of the appropriate national

This work was carried out as a part of the project "Audio-visual perception of acoustical environments", funded by the Deutsche Forschungsgemeinschaft (DFG MA 4343/1-1) within the framework of the research unit SEACEN, coordinated by Technische Universität Berlin and Rheinisch-Westfälische Technische Hochschule Aachen, Germany. We thank the staff of the performance rooms for their friendly cooperation, the Berlin Budapest Quartet (Dea Szücs, Éva Csermák, Itamar Ringel, Ditta Rohmann) and actress Ilka Teichmüller for their performances, Alexander Lindau, Fabian Brinkmann, and Vera Erbes for the in-situ acquisition of the rooms' acoustic and visual properties, Mina Fallahi for the geometric picture editing, Annika Natus, Alexander Haßkerl, and Shamir Ali-Khan for the 3D video shooting and post-production, and all test participants. Finally, we thank the two anonymous

reviewers for critically reading the manuscript and suggesting substantial
