Medical and nursing staff working in hospitals often experience exposure to extreme sound environments, and there is growing evidence of the negative impacts. Previous research highlighted various complexities regarding noise sources in hospitals; however, identifications of intrinsic noise categories that can reveal the complex mixture of existing hospital noise is still limited. The objective of this work was to identify intrinsic categories of the noise sources based on staff perceived annoyance and explore clear associations of these categorized noise sources with psychological perceptions. The staff perceptual responses regarding hospital noise were assessed by conducting surveys at the three pediatric and neonatal care units in two hospitals. Using principle component analysis (PCA), the psychological annoyance responses of 94 participants were used to derive the inherent structural patterns of the existing noise sources. The derived PCA categorization was validated on mixed-model analysis of variances, and employed on regression models to explore potential associations between the categorized noise factors and the staff's psychological perceptions. The results highlighted three intrinsic noise categories and their negative impacts on staff's psychological perceptions including work/rest disturbance and noisiness. Taken as a whole, the findings better reveal problematic noise source categories and establish a framework for hospital noise control that is less source-specific and more broadly generalizable.
医院的医护人员经常工作在极端的声音环境中，越来越多的证据表明这会产生负面影响。之前的研究强调了医院噪声源的各种复杂性；然而，能够揭示现有医院噪声复杂混合的内在噪声类别的识别仍然有限。这项工作的目的是根据工作人员的感知干扰来识别噪声源的内在类别，并探索这些分类噪声源与心理感知的明确关联。通过在两家医院的三个儿科和新生儿护理单元进行调查，评估工作人员对医院噪声的感知反应。使用主成分分析（PCA），对 94 名参与者的心理干扰反应进行分析，以得出现有噪声源的内在结构模式。基于混合模型方差分析对推导的 PCA 分类进行验证，并将其应用于回归模型，以探索分类噪声因素与工作人员心理感知之间的潜在关联。研究结果突出了三个内在噪声类别及其对工作人员心理感知的负面影响，包括工作/休息干扰和嘈杂。总的来说，这些发现更好地揭示了有问题的噪声源类别，并为医院噪声控制建立了一个框架，该框架不那么针对特定的噪声源，更具有广泛的通用性。
