Sažetak
The paper presents the results of two experiments carried out in the Auralization Laboratory at the University of Zagreb as a part of a research conducted in cooperation with KU Leuven. The experiments were designed to investigate the ability of a normal sighted person to assess room size and localize its own position within the room based only on available acoustical information, i.e. the room response to predefined stimuli. A total of 36 listeners took part in each experiment. For assessment of room size, four virtual rectangular rooms were defined: a small room with a volume of 30 m3, a medium-sized room and an elongated hallway of 252 m3 and a large room of 2016 m3. The investigation of self- localization was performed in a medium-sized room only. Acoustic treatment of the rooms was manipulated, i.e. the average absorption coefficient of a room and scattering coefficients of certain faces in a room were changed in a controlled manner. Two types of sources were used: a series of hand claps as a stationary source and footsteps as a moving source. All virtual environments were defined in ODEON® room acoustics software and the necessary sound files were encoded for 2nd order Ambisonics reproduction. The results of the experiments are statistically analyzed to determine whether or not the abilities of self localization and assessing room size can be confirmed at a given level of statistical significance.
