This study evaluated the noise level inside the incubators in a neonatal intensive care unit and identified its sources in order to attempt to reduce it. Although noise is not a proven risk factor as far as the sensory integrity of newborns is concerned, it is certainly an important cause of stress to them and a source of serious and dangerous changes in their behavioral and physiologic states. Noise recorded inside the incubators had two components. The first was background noise from the incubator motors, which varied from 74.2 to 79.9 dB, and was similar to environmental noise. The second source was impulsive events beyond 80 dB. These events were the result of voluntary and involuntary contact with the incubators' Plexiglas surface or to the abrupt opening and closing of their access ports. Considering its decibel levels and frequency, this latter component is undoubtedly an important source of stress to newborns. Moreover, these data reveal the need to train health care personnel on how to reduce such noise by taking more care in the handling of infants.
本研究评估了新生儿重症监护病房内暖箱的噪音水平，并确定其来源，以便尝试降低噪音。就新生儿的感官完整性而言，尽管噪音并非已证实的风险因素，但它肯定是给新生儿造成压力的一个重要原因，也是导致其行为和生理状态发生严重且危险变化的一个因素。在暖箱内记录到的噪音有两个组成部分。第一个是来自暖箱电机的背景噪音，其范围在74.2至79.9分贝之间，与环境噪音相似。第二个来源是超过80分贝的脉冲事件。这些事件是与暖箱的有机玻璃表面发生自愿或非自愿接触，或者暖箱入口突然打开和关闭所导致的。考虑到其分贝水平和频率，后一个组成部分无疑是给新生儿造成压力的一个重要来源。此外，这些数据表明有必要对医护人员进行培训，使其了解如何通过更小心地照料婴儿来降低此类噪音。
