摘要
针对中垂面内视觉刺激影响听觉声源定位的现象开展了心理声学实验。结合感知融合比例(判断视觉刺激与听觉刺激整合的比例)和跨模态定位偏差(听觉声源定位受视觉刺激影响的程度)对实验结果进行了分析。结果表明,视觉刺激和听觉刺激的相对位置改变导致感知融合的比例发生了显著变化。感知融合对听觉声源定位的影响显著,感知融合发生时,受试者对声源的定位分布在视觉刺激附近;感知融合未发生时,受试者对声源的定位不受视觉刺激影响,甚至会远离视觉刺激。
A psychoacoustic experiment is conducted to address the effect of visual stimulus on auditory sound source localization in the median plane.The experimental results are analyzed based on perceptual fusion rate(the proportion of perceptual unification of visual and auditory stimuli)and cross-modal localization bias(the degree to which auditory sound source localization is affected by visual stimulus).The results indicate that altering the relative locations of visual and auditory stimuli leads to significant variation in perceptual fusion rate.The effect of perceptual fusion on auditory sound source localization is significant.In the fusion cases,sound source localization is distributed near visual stimulus.In the non-fusion cases,sound source localization is unaffected by visual stimulus and even away from it.
