| 基于听觉感知的噪声语义描述是噪声声品质研究的基础性问题，已有研究未将语义描述与噪声来源、频谱特性以及产品运行状态等物理信息联系起来。该文分别针对飞机舱内噪声、车辆噪声和空气净化器噪声这3组典型噪声开展了主观评价实验，并通过多维尺度分析和主成分分析描述了3组噪声的语义空间，系统分析了不同类型噪声的描述词，同时解释了描述词与噪声物理属性之间的联系。研究发现：飞机舱内噪声、车辆噪声以及空气净化器噪声可以由4维、4维和3维语义空间进行描述；不同类型噪声在语义描述中具有共性与个性，3组噪声语义的主要维度均与嘈杂感相关，而噪声的个性描述词与其声源的物理属性密切相关；进行声品质建模及应用时，应同时考虑噪声共性和个性描述词对听觉感知的影响，采取有针对性的措施以提升产品声品质。该文从听觉感知的角度进行了噪声特性的语义描述和分析，研究结果可为产品声品质以及噪声控制研究提供帮助。 |
| 英文摘要: |
| Noise semantic description based on auditory perception is a basic problem of product sound quality research. Previous studies have not linked the semantic description with specific information such as noise source, spectrum characteristics and product operation status. Therefore, this paper carried out three subjective evaluation experiments on three groups of typical noise: aircraft cabin noise, vehicle noise and air purifier noise, described the semantic space of three groups of noise through multi-dimensional scale analysis and principal component analysis, and systematically analyzed the descriptors of different types of noise, at the same time, the relationship between descriptors and physical properties of noise is explained. It is found that: aircraft cabin noise, vehicle noise and air purifier noise can be described by 4-D, 4-D and 3-D semantic space. Different types of noise have commonness and individuality in semantic description. The main dimensions for the three groups of noise are related to the sense of noisy, and the individual descriptors of noise are closely related to the physical properties of their sound sources. When modeling and applying sound quality, the effects of noise commonness and individuality descriptors on auditory perception should be considered at the same time, and targeted measures should be taken to further improve the sound quality of products. In this paper, the semantic description and analysis of noise characteristics are carried out from the perspective of auditory perception. The results can provide help for the research of product sound quality and noise control. |
