摘要

通过相似度听力测试(MUSHRA)确定了与人声指向性空间分辨率相关的感知阈值。以高空间分辨率(球谐阶35)测量的人工说话头指向性数据为输入，通过房间声学模拟软件(RAVEN)构建不同房间声学条件和不同声源-接收机布置下的声音刺激。结果表明，在球谐波阶为8及以上时，语音信号不再被认为与最大分辨率有显著差异。提出了一种分析模型，与听力测试结果吻合较好。

Pilot study on the influence of spatial resolution of human voice directivity on speech perception

A perceptual threshold related to spatial resolution of the human voice directivity was determined through a listening test of similarity (MUSHRA). Directivity data of an artificial talking head measured at high spatial resolution (spherical harmonics order 35) was the input of a room acoustics simulation software (RAVEN) to build sound stimuli in various room acoustic conditions and source–receiver arrangements, with different voices. Results showed that, at spherical harmonics order 8 and above, the voice signal was not anymore perceived as significantly different from the greatest resolution. An analytical model was proposed and showed good agreement with the listening test results.

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.
