子宫结构保护胎儿免受高频声音（即，>500 Hz）。早产儿不受>500 Hz声音的影响。有必要评估声音频率，以保护早产儿免受高频声音的影响。然而，没有噪声测量研究报告使用声音频谱分析（SSA）。本文报告了两个三级新生儿重症监护病房（NICU）的SSA结果。SSA的结果表明，显着的高频声音存在于婴儿的直接护理环境。SSA评估的结果可能会提供证据支持临床管理人员寻求重新设计传统的NICU。
Uterine structures protect the fetus from high-frequency sounds (i.e., >500 Hz). Preterm infants are not protected from sound >500 Hz. It is necessary to assess sound frequencies to protect preterm infants from high-frequency sound. However, no noise measurement study has been reported using sound spectral analysis (SSA). This article reports the results of an SSA in two Level III neonatal intensive care units (NICUs). The results of the SSA indicated that significant high-frequency sound existed within the infant's immediate care environment. Results of SSA assessments may lend evidentiary support to clinical managers seeking to redesign traditional NICUs.
