The World Health Organisation (WHO) has established a maximum noise level of 40 decibels (dB) for an intensive care unit. The aim of this study was to compare the noise levels in 2 different intensive care units at a tertiary care centre.
Using a cross-sectional design study, an analysis was made of the maximum noise level was within the intensive coronary care unit and intensive care unit using a digital meter. A measurement was made in 4 different points of each room, with 5minute intervals, for a period of 60minutes 7:30, 14:30, and 20:30. The means of the observations were compared with descriptive statistics and Mann-Whitney U. An analysis with Kruskal-Wallis test was performed to the mean noise level.
The noise observed in the intensive care unit had a mean of 64.77±3.33dB (P=.08), which was similar to that in the intensive coronary care unit, with a mean of 60.20±1.58dB (P=.129). Around 25% or more of the measurements exceeded the level recommended by the WHO by up to 20 points.
Noise levels measured in intensive care wards exceed the maximum recommended level for a hospital. It is necessary to design and implement actions for greater participation of health personnel in the reduction of environmental noise.
世界卫生组织（WHO）规定重症监护病房的最大噪音水平为40分贝（dB）。本研究旨在比较一家三级护理中心两个不同重症监护病房的噪音水平。
采用横断面设计研究，使用数字仪表分析重症冠心病监护病房和重症监护病房内的最大噪音水平。在每个房间的4个不同点进行测量，每隔5分钟测量一次，持续60分钟，测量时间为7:30、14:30和20:30。将观测平均值与描述性统计数据和曼-惠特尼U检验进行比较。对平均噪音水平进行Kruskal-Wallis检验分析。
重症监护病房观测到的噪音平均为64.77±3.33dB（P = 0.08），与重症冠心病监护病房的平均噪音水平60.20±1.58dB（P = 0.129）相似。约25%或更多的测量值超过了WHO建议水平达20个点。
重症监护病房测量的噪音水平超过了医院建议的最大水平。有必要设计并实施相关行动，让医护人员更多地参与到降低环境噪音中来。
