Abstract

Compared to the general hospital, the children's hospital has significantly higher noise levels. This seriously influences hospital environment quality and medical service level. The noise characteristic and its influence were studied with field measurements and questionnaire surveys conducted in Kunming Children's Hospital. A-weighted equivalent continuous sound level (L_Aeq), percentile sound pressure levels, loudness and sharpness in waiting areas of cardiology, internal medicine, stomatology, intravenous blood collection and VIP departments were acquired and analyzed. Results showed that L_Aeq variation was consistent with the medical service schedule. The children's cries and the broadcast system were regarded as the main noise sources and their suddenness characteristic for a single event were analyzed. Questionnaire survey results revealed that more staff than patients in the waiting areas considered the sound environmental noisy. The ordered logit model analysis showed the subjective noisy evaluation of staff was significantly associated with ten percentile sound level (L₁₀) and five percentile loudness (N₅).

一家中国儿童医院候诊区的噪声特征及其影响分析。

与综合医院相比，儿童医院的噪音水平明显更高。这严重影响了医院的环境质量和医疗服务水平。通过在昆明市儿童医院进行实地测量和问卷调查，对其噪声特征及其影响进行了研究。获取并分析了心内科、内科、口腔科、静脉采血科、VIP 等科室候诊区的 A 加权等效连续声级（LAeq）、百分位数声压级、响度和锐度。结果表明，LAeq 的变化与医疗服务时间表一致。儿童哭声和广播系统被视为主要噪声源，并分析了它们在单一事件中的突发性特征。问卷调查结果显示，在候诊区认为声环境噪声大的工作人员多于病人。有序对数模型分析表明，工作人员的主观噪声评价与十百分位数声级（L10）和五百分位数响度（N5）显著相关。

期刊介绍： The Science of the Total Environment is an international journal dedicated to scientific research on the environment and its interaction with humanity. It covers a wide range of disciplines and seeks to publish innovative, hypothesis-driven, and impactful research that explores the entire environment, including the atmosphere, lithosphere, hydrosphere, biosphere, and anthroposphere. The journal's updated Aims & Scope emphasizes the importance of interdisciplinary environmental research with broad impact. Priority is given to studies that advance fundamental understanding and explore the interconnectedness of multiple environmental spheres. Field studies are preferred, while laboratory experiments must demonstrate significant methodological advancements or mechanistic insights with direct relevance to the environment.
