摘要

在评估环绕声扬声器再现时,通常会分析不同扬声器配置的感知效果。提出的工作有助于这一点,建模基于声学特性的各种复制格式的感知效应。通过对沉浸式音乐体验心理结构的实验研究,建立了沉浸式音乐聆听模型。根据浸入等级和声场特征之间的关系,对所提出的方法进行了评估,这些特征是通过在聆听位置使用球形麦克风阵列重新记录刺激而获得的。空间声场参数,如耳间相互关联(IACC),扩散和指向性被发现是特别相关的。此外,我们观察到,当扬声器数量更多时,浸入会达到饱和点,这被证实是可以从声场的物理性质来预测的。尽管与参与者和音乐作品相关的影响大于声场特征的影响,但所提出的方法被发现适用于预测人口平均评级,即普通听众对未知内容的沉浸感。该方法可以通过建立一个独立于特定扬声器设置的更通用的框架来补充现有的多声道扬声器再现研究。

Towards predicting immersion in surround sound music reproduction from sound field features
When evaluating surround sound loudspeaker reproduction, perceptual effects are commonly analyzed in relationship to different loudspeaker configurations. The presented work contributes to this by modeling perceptual effects based on acoustic properties of various reproduction formats. A model of immersion in music listening is derived from the results of an experimental study analyzing the psychological construct of immersive music experience. The proposed approach is evaluated with respect to the relationship between immersion ratings and sound field features obtained from re-recordings of the stimuli using a spherical microphone array at the listening position. Spatial sound field parameters such as inter-aural cross-correlation (IACC), diffuseness and directivity are found to be of particular relevance. Further, immersion is observed to reach a point of saturation with greater numbers of loudspeakers, which is confirmed to be predictable from the physical properties of the sound field. Although effects related to participants and musical pieces outweigh the impact of sound field features, the proposed approach is found to be suitable for predicting population-average ratings, i.e. immersion experienced by an average listener for unknown content. The proposed method could complement existing research on multichannel loudspeaker reproduction by establishing a more generalizable framework independent of particular speaker setups.

期刊介绍: Acta Acustica, the Journal of the European Acoustics Association (EAA). After the publication of its Journal Acta Acustica from 1993 to 1995, the EAA published Acta Acustica united with Acustica from 1996 to 2019. From 2020, the EAA decided to publish a journal in full Open Access. See Article Processing charges. Acta Acustica reports on original scientific research in acoustics and on engineering applications. The journal considers review papers, scientific papers, technical and applied papers, short communications, letters to the editor. From time to time, special issues and review articles are also published. For book reviews or doctoral thesis abstracts, please contact the Editor in Chief.
