This study investigates the dynamic auditory perception in large sequential public spaces for listeners in motion with a stationary primary sound source. Virtual soundwalks, involving four music and voice sources and validated with in situ soundwalks, were conducted in an exhibition space. The perception differences between the approaching and receding sound sources were explored, and three major effects were found. The rising sound received a higher rating in each room with a greater perceived change in the loudness than the falling sound despite equal changes in both levels (approach effect). The difference was greater for the room connected to the source room. The loudness in the room connected to the source room receives a sharp drop (plummet effect) for the receding sound source, which was larger for music than for voice. The effect of the background sound impairing the perceptual priority of rising sound was profound in the receiving rooms. The loudness patterns could not be extended to other perceptual attributes, including reverberation. An increasing symmetry of the overall perception between the different sound source types was observed (convergence effect) either by the approaching or receding sound sources. The overall asymmetry of the directional aspects occurring with the noise and voice was not as distinguishable as with music.
本研究调查了大型连续公共空间中运动听众对固定声源的动态听觉感知。在展览空间中进行了涉及四个音乐和语音源的虚拟声音漫步，并通过实地声音漫步进行了验证。探索了趋近和退离声源之间的感知差异，发现了三个主要效应。与下降声音相比，上升声音在每个房间的评分都更高，尽管两个水平的变化相等（接近效应）。与声源房间相连的房间差异更大。对于退离声源，与声源房间相连的房间的响度会急剧下降（骤降效应），对于音乐来说比对于语音来说更大。背景声音对接收房间中上升声音的感知优先级的影响很大。响度模式无法扩展到其他感知属性，包括混响。无论是趋近还是退离声源，不同声源类型的整体感知对称性都在增加（收敛效应）。与音乐相比，噪声和语音的方向性方面的整体不对称性不太明显。
