摘要

国际标准化组织(ISO)引入了“音景”一词,将后者定义为“人在语境中感知或理解的声音环境”。它提出了定量评估人类对声音环境的情绪反应的方法。在其中一种方法中,这样的反应被表示为愉快-事件平面上的坐标。愉快坐标评估的是测试对象在测试时所处环境的愉快程度,即测试对象的性质;事件坐标评估的是环境的事件程度,即测试对象的性质。本研究的目的是验证标准的ISO方法。因此,在不同地点对环境进行了视听检查;计算愉快度和事件度坐标;记录和计算环境的声学和心理声学特征,然后将后者与声景(或愉快和事件坐标)的特征进行比较。研究表明,物理特征高于既定卫生标准的良好环境很可能使人感到愉快。结果证实了声景评估方法的有效性、信息量和完整性,以及非专业专家的可及性。声景观的特点可用于城市声环境的工程设计。

Soundscapes in the Urban Environment: Audiovisual Perception and Objective Control

Soundscapes in the Urban Environment: Audiovisual Perception and Objective Control

The International Organization for Standardization (ISO) introduced the term “soundscape,” which defined the latter as “an acoustic environment perceived or understood by a person/people in context.” It proposed methods for quantitatively assessing human emotional reactions to a sound environment. In one of the methods, such reactions were represented as coordinates on the Pleasantness–Eventfulness plane. The pleasantness coordinate assessed how pleasant the environment was for the subject at the time of the examination, i.e., the properties of the subject, and the eventfulness coordinate assessed how eventful the environment was, i.e., the properties of the environment. The aim of this study was to verify the standard ISO method. Therefore, an audiovisual examination of the environment was carried out in different locations; pleasantness and eventfulness coordinates were calculated; acoustic and psychoacoustic characteristics of the environment were recorded and calculated, and the latter were then compared with the characteristics of soundscapes (or pleasantness and eventfulness coordinates). It was shown that a sound environment with physical characteristics higher than established sanitary standards may well be pleasant for a person. The results confirmed the validity, informativeness, and integrity of the method for assessing soundscapes, as well as its accessibility for nonprofessional experts. The characteristics of soundscapes can be used for engineering design of the sound environment of urban areas.
