. -- (NOTE: THERE IS NOW A SECOND VERSION OF THIS ONLINE LISTENING EXPERIMENT.) Last September (2020) we published the article “Recognizing individual concert halls is difficult when listening to the acoustics with different musical passages”. The title already tells a lot of this experiment, where the subjects were required to recognize halls just by listening to the room acoustics, but so that the sounds (i.e. excitations) were either exactly the same or different.

. -- In this post I will briefly discuss and illustrate the analysis of perceptual matching experiment on concert hall acoustics. How the sound samples / auralizations of concert hall acoustics in this experiment were made is a topic of another time. (This presentation is prepared for and presented in the “Acoutect Research and Demonstrator Workshop 5” held at Aalto University in 20-24 January 2020) Introduction The background of the experiment is on our previous research on concert hall acoustics with the loudspeaker orchestra and spatial sound / multichannel auralization techniques that we have conducted at Aalto Uni.
