Abstract :This study proposes a method for evaluation and ranking attributes in 3D audio based on their functionality. According to the proposed method, a list of attributes is created from the existing research about surround and 3D sound attributes. The Semantic Differential Scale is suggested as an evaluation method. Dimensions for the semantic differential scale are offered, which are importance, comprehensibility, and noticeability. The methodology uses a weight assignment process based on expert panel opinions, minimizing individual error. The weighted average scores from the assessors that participate in the evaluation phase are combined to create a functionality score. This score is used to rank the attributes according to their functionality, which is the operationalized result of three dimensions. The study also suggests providing musical context to subjects during evaluation, allowing them to focus on the attributes. Finally, procedures such as data arrangement, rank listing, statistical and comparative analysis methods are explained.
