Construction of an auralization laboratory based on multichannel loudspeaker system

As a contribution to addressing the current issues that have been brought up recently in the field of acoustic research related to auralization of sound in both indoor and outdoor spaces, an auralization laboratory based on multichannel loudspeaker reproduction techniques such as Vector-Based Amplitude Panning, multichannel surround or Ambisonics has been constructed at the University of Zagreb, being the first and only laboratory of this kind in Croatia. The paper represents construction details and the overall progress up to date, as well as desired vs. achieved conditions in the laboratory, regarding the acoustical properties of the room such as the reverberation time, the existence of room modes, the background noise level in the laboratory, etc. Problems and difficulties encountered during construction are described as well, taking into account the position of the given space within the building and the surrounding outdoor environment, the function of the surrounding spaces in the building and the manner in which the building itself was constructed. Suitability of the laboratory for different applications is discussed in light of current demands related to the ongoing research.
