Spectral Analysis of Noise in the Neonatal Intensive Care Unit.

本研究旨在探讨新生儿加护病房及保育箱内之声级及频率。录音的总时间几乎是10个小时。声音水平高于美国儿科学会推荐的水平。频率水平的范围也相对较宽，从不到1 kHz到大约6 kHz，尽管音量几乎相同。早产儿对低频声音没有反应。这些结果表明，评价声音的频率水平可能是有用的，以减少压力的噪音早产儿在重症监护室。

The purpose of this study was to investigate the sound level and frequency level in the neonatal intensive care unit and inside incubators. The total time for recording sound was almost 10 hours. The sound level was higher than that recommended by the American Academy of Pediatrics. The range of frequency levels was also relatively wide, from less than 1 kHz to approximately 6 kHz, even though the sound volume was almost the same. Premature infants did not react to low frequency sound. These results indicate that evaluation of frequency levels of sound may be useful for reducing stressful noise for premature infants in the intensive care nursery.
