通过对北京4个开放式办公室的声环境特性测试以及一系列现场问卷调查,研究了对汉语背景下开放式办公室声环境评价的特点及其与客观声学参数之间的关系。分析发现:汉语背景下人们对声环境的关注程度仅次于光线,并对语言私密性有一定的要求;声环境评价与办公室的工作性质有关,但均在“不好不坏”和“糟糕”之间;声环境评价与背景噪声L_(Aeq)和L_(10)显著相关,采用混响时间作为单一指标来评价声环境的方法存在明显不足;当减少语言传输指数STI时,可以同时提高语言私密度和改善声环境;声环境认知、声响大小的敏感度、情绪和疲劳等主观因素对声环境评价具有显著性影响,而工作注意力集中程度、每天工作时间、年龄、收入、职位等则影响不显著。
Through the testing of the acoustic environment characteristics of four open offices in Beijing and a series of field questionnaires, the characteristics of the open office acoustic environment evaluation in Chinese context and its relationship with the objective acoustic parameters were studied. The analysis shows that people pay more attention to the acoustic environment than the light in the background of Chinese, and have certain requirements on the privacy of the language. The evaluation of the acoustic environment is related to the nature of the work in the office, but both are in the “not bad” and “ ”Bad"; the acoustic environment evaluation is significantly related to the background noise L_ (Aeq) and L_ (10), and the method of using the reverberation time as a single index to evaluate the acoustic environment is obviously insufficient; when reducing the speech transmission index STI, Subjective factors such as acoustic environment cognition, sound size sensitivity, emotion and fatigue have a significant influence on the acoustic environment assessment, and work concentration, daily work time, age, Income, post and other effects are not significant.
