聽覺數量判斷受方位角、仰角與距離之外的非空間因素影響

// Auditory Numerosity Judgement Is Driven by Non-Spatial Factors Across Azimuth, Elevation, and Distance

本研究探討聽者如何估測同時出現的聲源數量（聽覺數目感），並分析方位角、仰角與距離三個空間維度｜結果發現數目判斷與空間聽覺精準度及語音清晰度無關｜主要受聲音頻率與時間複雜度影響，顯示聽覺數目感依賴整體聲場特徵而非精確空間線索。

// This study investigated how listeners estimate the number of simultaneous sound sources (auditory numerosity) along spatial dimensions of azimuth, elevation, and distance. By isolating these spatial axes, the researchers found that numerosity judgments did not depend on spatial hearing accuracy or speech intelligibility. Instead, perceived numerosity was mainly influenced by the overall spectrotemporal complexity of the sound mixture. The results suggest that auditory numerosity relies on general scene-level representations rather than precise spatial cues.
