新生儿重症监护病房（NICU）的噪声暴露一直高于目前的建议。这可能会对新生儿的睡眠、体重增加和整体健康产生不利影响。我们试图评估一种新的有源噪声控制（ANC）系统的效果。在模拟NICU环境中，将ANC设备的降噪性能与贴附泡沫耳罩的降噪性能进行比较，以响应警报和语音。ANC装置的降噪区用相同的警报和语音集合来量化。ANC装置在所测试的八个声音序列中的七个中提供了比耳罩更大的降噪，其中实现了比刚刚可察觉的差异更大的降噪。对于500 Hz倍频程带中的噪声，ANC设备在整个预期患者位置上表现出一致的降噪效果。对于1000 Hz以下的噪声，它比1000 Hz以上的噪声提供了更好的性能。ANC装置通常为耳罩提供了上级降噪，并且在婴儿将被放置在保育箱内的整个范围内提供了降噪区。患者的睡眠和体重增加的影响进行了讨论。主动式噪音控制装置可有效降低婴儿保育箱内因床边装置警报而产生的噪音。这是第一次分析基于恒温箱的有源噪声控制设备，并与粘贴在耳上的硅胶耳罩进行比较。非接触式降噪装置可能是降低住院早产儿噪声暴露的适当方法。
Noise exposure in the neonatal intensive care unit (NICU) is consistently higher than current recommendations. This may adversely affect neonatal sleep, weight gain, and overall health. We sought to evaluate the effect of a novel active noise control (ANC) system. An ANC device’s noise reduction performance was compared to that of adhesively affixed foam ear covers in response to alarm and voice sounds in a simulated NICU environment. The zone of noise reduction of the ANC device was quantified with the same set of alarm and voice sounds. The ANC device provided greater noise reduction than the ear covers in seven of the eight sound sequences tested in which a noise reduction greater than the just noticeable difference was achieved. For noise in the 500 Hz octave band, the ANC device exhibited consistent noise reduction throughout expected patient positions. It provided better performance for noise below 1000 Hz than above 1000 Hz. The ANC device provided generally superior noise reduction to the ear covers and provided a zone of noise reduction throughout the range where an infant would be placed within an incubator. Implications for patient sleep and weight gain are discussed. Active noise control device can effectively reduce noise inside an infant incubator due to bedside device alarms. This is the first analysis of an incubator-based active noise control device and comparison to adhesively affixed silicone ear covers. A non-contact noise reduction device may be an appropriate means of reducing noise exposure of the hospitalized preterm infant.
