采用客观物理分析和主观问卷调查相结合的方法,探讨了不同类型园林水景声音特性和被人们喜欢的程度。首先,使用专业声学设备对济南市的46个水景声音进行采集与测量,选取15个典型水景声音进行研究。分析水景声音的声压级和频谱图像等物理特性。在半消声室内回放录制的水景声音并进行问卷调查。研究水景声音的物理特性、视觉影像和主观描述与喜好度之间的关系。得到以下结论:人们不喜欢声压级大、频谱曲线平直的大流速流量水景的声音;水景周边环境对小流速流量水景声音音质影响明显;水景的视觉影像影响水景声音被喜欢的程度;人们喜欢“舒缓的”水景声,不喜欢“急促的、低沉的”水景声;喜欢“潺潺”的水景声,不喜欢“轰轰”的水景声。
Using the method of objective physical analysis and subjective questionnaire survey, this paper discusses the sound characteristics of different types of garden water features and the extent to which people like it. First of all, we use professional acoustic equipment to collect and measure 46 waterscape sounds in Jinan, and select 15 typical waterscape sounds for research. Analysis of water features sound pressure level and spectral images and other physical characteristics. Recorded sound recordings of water features in semi-anechoic chambers and questionnaires. Study the physical characteristics of water features sound, visual images and subjective description of the relationship between preferences. The following conclusions are drawn: People do not like the sound of large flow velocity water level with large sound pressure level and straight spectral curve; the surrounding environment of water landscape has obvious influence on the sound quality of water flow sound of small flow rate; the visual image of water landscape affects the degree of water sound being liked; Like “soothing ” water view, do not like “rapid, low ” water view; like “murmuring ” water view, do not like “roaring ” water view sound.
