State of the Art on Subjective Assessment of Spatial Sound Quality
A new aim of sound technologies is spatial reproduction, which raises new questions about their quality assessment.

But, they are restricted to the evaluation of the overall quality. The finding, through various studies, of some features specific to surround sound drove us to wonder whether they can be included in a new quality assessment.
