Observational, descriptive and cross-sectional study carried out in two PICU with different infrastructure: bays separated by curtains and individual bedrooms. A PCE-999 sound level meter was used to determine noise levels, which were registered in decibels (dB). At the same time, an ad hoc data recording document was designed in which we differentiated between each unit (open concept or closed), time of recording.
A total of 330 tests, 72 from open PICUs and 258 from closed PICUs were collected. The noise in the open PICU was 56.74 ± 3.61 decibels versus 50.36 ± 4.71 in the closed PICU, obtaining the highest levels during the morning.
As it occurs in other studies, noise levels exceed the allowed limits. At the same time, the main sources of noise in the PICU came from alarms, medical equipment, such as monitors or respirators, and conversations between health professional.
This investigation has shown high levels of environmental noise in the two PICUs analysed. The data obtained indicate that the architectural concept of individual bedrooms may have an impact in decreasing this environmental input.
1）确定一家三甲医院的两个儿科重症监护病房（PICU）的噪声水平，2）分析这些值是否符合现行标准。
在两个具有不同基础设施的 PICU 中进行观察性、描述性和横断面研究：用窗帘隔开的小隔间和单独的卧室。使用 PCE-999 声级计测量噪声水平，并以分贝（dB）记录。同时，设计了一个专门的数据记录文档，其中我们区分了每个单元（开放式或封闭式）和记录时间。
共收集了 330 次测试，其中 72 次来自开放式 PICU，258 次来自封闭式 PICU。开放式 PICU 的噪声为 56.74 ± 3.61 分贝，而封闭式 PICU 的噪声为 50.36 ± 4.71 分贝，在早上达到最高水平。
正如其他研究所示，噪声水平超过了允许的限制。同时，PICU 中的主要噪声源来自警报、监护仪或呼吸机等医疗设备以及医护人员之间的对话。
这项调查表明，在所分析的两个 PICU 中，环境噪声水平较高。所获得的数据表明，单独卧室的建筑概念可能会对降低这种环境输入产生影响。
