A common lexicon for spatial sound quality assessment - latest developments

This paper reports the latest developments in ongoing research to establish a common lexicon of sound quality attributes agnostic to the application under study. It expands on earlier work with the definition of attributes for the evaluation of spatial sound reproduction. A panel of 12 specialized expert assessors was used to expand the lexicon to incorporate spatial sound characteristics. The discussions were based on the results of a semantic clustering of relevant quality attribute sets proposed in the literature. The updated lexicon is presented, with detailed definitions, scale labels and examples provided for the attributes. Further review and formal validation are required in future.
