Evaluation of Auralization Results

There are several factors that affect the quality of auralization. Most important of them are the accuracy of room acoustic modeling and the properties of the spatial sound reproduction. These topics have gained lots of research, but still evaluation of the auralization quality is an unsolved problem. In this paper we make a short review on the performed and published evaluations. Most remarkable issues affecting the quality are discussed in more detail. As a conclusion we present that a round-robin comparison for auralization systems should be performed, similarly as earlier done with room acoustic modeling programs.
