摘要

在新生儿紧急地面和空中运输过程中的振动和噪声暴露被认为是对新生儿的危害;然而，没有标准化的测试环境可以可靠地量化这种高重复性的暴露。为了在标准化测试环境的开发中使用，进行了一次道路测试，以提供道路振动的定量测量。本文详细介绍了救护车的道路试验仪器、分析和结果。在道路上的研究结果表明，新生儿经历的振动超过了成年人的标准;新生儿加速度的功率谱密度在人类最敏感的频率范围(1-20 Hz)内包含峰值(2 Hz和9 Hz);考虑的病人运输系统的阻尼固有频率为9.5 Hz。

Characterizing On-Road Vibrations in Ontario’s Neonatal Patient Transport

Vibration and noise exposure during emergency neonatal ground and air transport are recognized as hazards for the neonate; however, no standardized test environment exists to reliably quantify such exposure with high repeatability. An on-road test was performed to provide a quantitative measurement of on-road vibrations to be used in the development of the standardized test environment. This paper details the ambulance on-road test instrumentation, analysis, and results. On-road findings indicate that neonates experience vibrations that exceed adult standards; that the power spectral density of the acceleration at the neonate contains peaks (at 2 Hz and 9 Hz) in the frequency range humans are most sensitive (1-20 Hz); and that the damped natural frequency of the patient transport system considered is 9.5 Hz.
