Jamilla Balint is a postdoc at RWTH Aachen University, Aachen, Germany. She received her PhD in acoustics from the Graz University of Technology, Graz, Austria, and her MSc degree in electrical and audio engineering from the University for Music and Performing Art Graz and the Graz University of Technology. She was a visiting researcher at the Technical University of Denmark, Kongens Lyngby. For her PhD, she investigated the reasons for the nonlinearity of sound decays and the consequences of absorption measurements in reverberation chambers. Currently, her research focuses on interdisciplinary collaborations in acoustics, psychology, and virtual reality for auditory cognition experiments.

Michael Vorländer studied physics in Aachen, Germany, where he finished his doctoral degree in 1989 with a thesis in room acoustical computer simulation. He has worked in various fields of acoustics such as psychoacoustics, electroacoustics, and architectural acoustics. Since 1996, he has been a professor at the Institute for Hearing Technology and Acoustics, RWTH Aachen University, Germany. He served in several organization Aachen, as president (European Acoustics Association [EAA] 2004-2007; International Commission for Acoustics [ICA] 2011-2013) and as an Executive Council member (Acoustical Society of America 2017-2019). His research focus is auralization.
