Abstract

One of the most effective approaches to fostering a healthy living environment is the development of soundscape planning and design technologies that harmonize the subjective experiences of the public with urban ecological planning. Urban parks, as primary habitats for urban birds, play a vital role in shaping the urban soundscape through birdsong. This study investigated 18 urban parks in Kunming, China, and classified the songs of 28 bird species with a dominance degree greater than 1 using Log-Mel acoustic characteristics. Public responses were assessed across three dimensions: auditory, physiological, and psychological. Among the various birdsong types, the Frequency Modulated (FM) type showed the most beneficial responses in terms of Heart Rate (HR), Heart Rate Variability (HRV), Skin Conductance (SC), and psychological well-being. In contrast, the Broadband with Varying Frequency (BVF) type induced greater irritability and reduced calmness, showing limited positive effects confined only to HR-related physiological indicators. The results indicate that the higher the physiological and psychological benefits of a birdsong, the stronger the public’s perceptual preference. Based on both the physiological characteristics of birds and public perception, this study proposes strategies to construct and optimize birdsong soundscapes in urban parks of various scales. Moreover, it was found that the overall quality of birdsong in Kunming’s urban parks was at a satisfactory level. Importantly, the acoustic types of birdsong were found to be significantly associated with multidimensional public responses. The FM type elicited predominantly positive outcomes, whereas the BVF type showed comparatively weaker or even adverse effects. This research provides novel theoretical and practical guidance for the enhancement of urban birdsong soundscapes. Notably, it is the first study to apply Log-Mel acoustic feature classification to investigate public perceptual differences in response to birdsong.

基于听觉的城市公园内公众对不同类型鸟鸣的多维响应——以昆明为例

营造健康生活环境的最有效方法之一是发展声景规划和设计技术，使公众的主观体验与城市生态规划相协调。城市公园作为城市鸟类的主要栖息地，在通过鸟鸣塑造城市声景方面发挥着至关重要的作用。本文以昆明18个城市公园为研究对象，利用Log-Mel声学特征对优势度大于1的28种鸟类的鸣声进行了分类。公众的反应从三个方面进行了评估：听觉、生理和心理。在不同的鸣声类型中，调频（FM）类型在心率（HR）、心率变异性（HRV）、皮肤电导（SC）和心理健康方面表现出最有益的反应。相比之下，变频宽带（BVF）类型会导致更大的烦躁和更低的冷静，仅在hr相关生理指标上显示有限的积极作用。结果表明，鸟鸣的生理和心理效益越高，公众的感知偏好越强。基于鸟类的生理特征和公众感知，本研究提出了不同尺度城市公园鸟鸣声景观的构建和优化策略。此外，昆明城市公园鸟鸣的整体质量处于令人满意的水平。重要的是，发现鸟鸣的声学类型与多维公众反应显着相关。FM型以阳性结果为主，而BVF型则表现出相对较弱甚至不良的效果。该研究为城市鸟鸣声景观的强化提供了新的理论和实践指导。值得注意的是，这是首次应用Log-Mel声学特征分类来研究公众对鸟鸣反应的感知差异。

期刊介绍： Since its launch in 1968, Applied Acoustics has been publishing high quality research papers providing state-of-the-art coverage of research findings for engineers and scientists involved in applications of acoustics in the widest sense. Applied Acoustics looks not only at recent developments in the understanding of acoustics but also at ways of exploiting that understanding. The Journal aims to encourage the exchange of practical experience through publication and in so doing creates a fund of technological information that can be used for solving related problems. The presentation of information in graphical or tabular form is especially encouraged. If a report of a mathematical development is a necessary part of a paper it is important to ensure that it is there only as an integral part of a practical solution to a problem and is supported by data. Applied Acoustics encourages the exchange of practical experience in the following ways: • Complete Papers • Short Technical Notes • Review Articles; and thereby provides a wealth of technological information that can be used to solve related problems. Manuscripts that address all fields of applications of acoustics ranging from medicine and NDT to the environment and buildings are welcome.
