The purpose of this study was to identify the noise level and frequency experienced by premature infants receiving incubator care in the neonatal intensive care unit (NICU).
The participants were 20 premature infants receiving incubator care in the NICU of a university hospital in Daejeon Metropolitan city. The noise level was measured using a professional sound-level meter (ET-958, FLUS, Shenzhen, China) based on a noise classification table developed by the author. The data were analyzed with descriptive statistics, the t-test, analysis of variance, and Pearson correlation coefficients using SPSS for Windows version 22.0.
The average noise level experienced by premature infants receiving incubator care in the NICU was 51.25 dB (range: 45.0~81.7 dB). The frequency of noises was highest for factors related to nursing activities (40.3%), followed by human factors (29.1%), machine alarm sounds (20.1%), incubator operation (6.6%), and internal environmental factors (3.9%).
According to the above results, the noise level experienced by premature infants receiving incubator care in the NICU exceeded the recommendations of the American Academy of Pediatrics. Therefore, it is necessary to develop an interventional program to reduce noise in the NICU, and to conduct follow-up studies to verify its effectiveness.
本研究旨在确定新生儿重症监护病房（NICU）中接受暖箱护理的早产儿所经历的噪音水平和频率。
研究对象为大田广域市一所大学医院NICU中20名接受暖箱护理的早产儿。根据作者制定的噪音分类表，使用专业声级计（ET - 958，深圳福禄克）测量噪音水平。使用SPSS for Windows 22.0版本对数据进行描述性统计、t检验、方差分析和Pearson相关系数分析。
NICU中接受暖箱护理的早产儿所经历的平均噪音水平为51.25分贝（范围：45.0~81.7分贝）。与护理活动相关的因素产生的噪音频率最高（40.3%），其次是人为因素（29.1%）、机器警报声（20.1%）、暖箱操作（6.6%）和内部环境因素（3.9%）。
根据上述结果，NICU中接受暖箱护理的早产儿所经历的噪音水平超过了美国儿科学会的建议。因此，有必要制定一项降低NICU噪音的干预计划，并进行后续研究以验证其有效性。
