Although there have been numerous studies investigating subjective spatial impression in rooms, only a few of those studies have addressed the influence of visual cues on the judgment of auditory measures. In the psychophysical study presented here, video footage of five solo music/speech performers was shown for four different listening positions within a general-purpose space. The videos were presented in addition to the acoustic signals, which were auralized using binaural room impulse responses (BRIR) that were recorded in the same general-purpose space. The participants were asked to adjust the direct-to-reverberant energy ratio (D/R ratio) of the BRIR according to their expectation considering the visual cues. They were also directed to rate the apparent source width (ASW) and listener envelopment (LEV) for each condition. Visual cues generated by changing the sound-source position in the multi-purpose space, as well as the makeup of the sound stimuli affected the judgment of spatial impression. Participants also scaled the direct-to-reverberant energy ratio with greater direct sound energy than was measured in the acoustical environment.
尽管已有大量研究调查了房间内的主观空间印象，但只有少数研究涉及视觉线索对听觉测量判断的影响。在本心理物理学研究中，为五个独奏音乐/演讲者的视频片段展示了在一个通用空间内的四个不同的聆听位置。这些视频与声学信号一起呈现，使用在同一通用空间中记录的双耳房间脉冲响应 (BRIR) 进行了听觉化。参与者被要求根据他们的视觉线索的预期，调整 BRIR 的直达声与混响声能量比（D/R 比）。他们还被要求为每种情况评估表观声源宽度（ASW）和听众包围度（LEV）。通过在多功能空间中改变声源位置以及声音刺激的组成产生的视觉线索会影响空间印象的判断。参与者还根据比在声学环境中测量到的更大的直达声能量来调整直达声与混响声能量比。
