摘要

了解技术系统参数对视听体验的影响对技术人员优化体验具有重要意义。本研究的重点是音频空间化的变化(将音频渲染的扬声器配置从2.1到5.1再到7.1.4)对沉浸体验的影响。首先，进行幅度估计实验，对包络度进行感知评估，以验证音频空间化水平之间存在感知差异的初始条件。结果表明，包络度从2.1繁殖增加到5.1繁殖，但从5.1繁殖增加到7.1.4繁殖没有显著的效益。采用绝对评分实验范式对24名参与者进行了四种视听体验的沉浸性评估。沉浸感得分之间的明显差异无法确定，这表明音频空间化的变化和随后的包络变化并不能保证心理上的沉浸体验。

Influence of Changes in Audio Spatialization on Immersion in Audiovisual Experiences

Understanding the influence of technical system parameters on audiovisual experiences is important for technologists to optimize experiences. The focus in this study was on the influence of changes in audio spatialization (varying the loudspeaker configuration for audio rendering from 2.1 to 5.1 to 7.1.4) on the experience of immersion. First, a magnitude estimation experiment was performed to perceptually evaluate envelopment for verifying the initial condition that there is a perceptual difference between the audio spatialization levels. It was found that envelopment increased from 2.1 to 5.1 reproduction, but there was no significant benefit of extending from 5.1 to 7.1.4. An absolute-rating experimental paradigm was used to assess immersion in four audiovisual experiences by 24 participants. Evident differences between immersion scores could not be established, signaling that a change in audio spatialization and subsequent change in envelopment does not guarantee a psychologically immersive experience.
