Sažetak
This article reports results of two experiments performed in a collaboration between the University of Zagreb, Croatia, and KU Leuven, Belgium. Four different rectangular rooms are simulated and compared: a small room of 30m2, a large room of 2016m2, a medium size room and a corridor with the same volume 252m2. The average sound absorption and scattering coefficient in the 4 mentioned rooms are varied. Auralizations were performed for 2 stimuli: a sequence of hand-claps (expressing the sound that a listening person would produce him/herself) and human steps (expressing a person passing by). In the first experiment we investigate how much information about the shape and a size of the room is a normally sighted person is able to grasp from purely acoustical stimuli, presented over headphones. This experiment was performed in the medium size room. In the second experiment, the accuracy of a listening person to indicate her/his position was assessed in the 4 virtual rooms. The virtual environments were created in Odeon® software and the results were statistically analyzed.
