Abstract

The auditory signals at the ear can be affected by components arriving both directly from a sound source and indirectly via environmental reverberation. Previous studies have suggested that the perceptual separation of these contributions can be aided by expectations of likely reverberant qualities. Here, we investigated whether vision can provide information about the auditory properties of physical locations that could also be used to develop such expectations. We presented participants with audiovisual stimuli derived from 10 simulated real-world locations via a head-mounted display (HMD; n = 44) or a web-based ( n = 60) delivery method. On each trial, participants viewed a first-person perspective rendering of a location before hearing a spoken utterance that was convolved with an impulse response that was from a location that was either the same as (congruent) or different to (incongruent) the visually-depicted location. We find that audiovisual congruence was associated with an increase in the probability of participants reporting an audiovisual match of about 0.22 (95% credible interval: [ 0.17 , 0.27 ]), and that participants were more likely to confuse audiovisual pairs as matching if their locations had similar reverberation times. Overall, this study suggests that human perceivers have a capacity to form expectations of reverberation from visual information. Such expectations may be useful for the perceptual challenge of separating sound sources and reverberation from within the signal available at the ear.

模拟环境中声音和视觉的关联。
耳中的听觉信号可以受到直接来自声源的分量和间接通过环境混响到达的分量的影响。先前的研究表明,这些贡献的感性分离可以通过对可能的回响质量的预期来辅助。在这里,我们研究了视觉是否可以提供关于物理位置的听觉特性的信息,这些信息也可以用来发展这种期望。我们通过头戴式显示器(HMD)向参与者提供来自10个模拟现实世界地点的视听刺激。N = 44)或基于网络的交付方式(N = 60)。在每次试验中,参与者在听到与视觉上描绘的位置相同(一致)或不同(不一致)的位置的脉冲反应相关联的口头话语之前,先观看一个地点的第一人称视角渲染。我们发现,视听一致性与参与者报告视听匹配的概率增加有关,约为0.22(95%可信区间:[0.17,0.27]),如果他们的位置有相似的混响时间,参与者更有可能将视听对混淆为匹配。总的来说,这项研究表明,人类感知者有能力从视觉信息中形成对回响的期望。这样的期望可能对从耳朵可用的信号中分离声源和混响的感知挑战有用。

期刊介绍: Multisensory Research is an interdisciplinary archival journal covering all aspects of multisensory processing including the control of action, cognition and attention. Research using any approach to increase our understanding of multisensory perceptual, behavioural, neural and computational mechanisms is encouraged. Empirical, neurophysiological, psychophysical, brain imaging, clinical, developmental, mathematical and computational analyses are welcome. Research will also be considered covering multisensory applications such as sensory substitution, crossmodal methods for delivering sensory information or multisensory approaches to robotics and engineering. Short communications and technical notes that draw attention to new developments will be included, as will reviews and commentaries on current issues. Special issues dealing with specific topics will be announced from time to time. Multisensory Research is a continuation of Seeing and Perceiving, and of Spatial Vision.
