Sound Judgment: A Multi-Year Evaluation of Audio Aesthetics and Gameplay Impact in DareFightingICE Sound Design Competition

Abstract

This paper presents a multi-year evaluation (2022-2024) of winning entries from the DareFightingICE Sound Design Competition, analyzing the interplay between audio aesthetics and gameplay functionality for visually impaired players and the Blind AI agent. Through user studies (n = 26 and n = 21) and a comprehensive ablation study of the 2024 winning sound design, we reveal three key findings: (1) While winning entries consistently achieved high aesthetic ratings, scores plateaued despite year-on-year improvements in Blind AI performance, indicating a decoupling of these dimensions; (2) Systematic muting identified 'critical' sounds whose absence severely impaired AI decision-making, whereas static background music introduced detrimental noise; (3) Drastically reducing sound design to 10% of sound effects degraded both AI win ratios and human aesthetic perception. These results demonstrate that practical accessible audio requires prioritizing unambiguous cues for frequent actions, minimizing sonic redundancy like non-adaptive BGM, and validating sound designs through dual AI/human evaluation. We provide actionable strategies for designers targeting future competitions and inclusive gaming.
