The purpose of this study was to determine the amount of vibration transmitted to the surface of an incubator mattress. Empty incubators with metal (n = 12) and non-metal (n = 12) bases were monitored for vibration levels when the incubators were turned "off" and when they were turned "on." High levels of low-frequency vibration were detected in both types of incubators in both conditions. The metal incubators transmitted significantly less vibration to the mattress than did the non-metal incubators at several frequencies in the "off," the "on," and the "adjusted" conditions. These results suggest that infants experience significant whole-body vibration while lying in incubators.
本研究的目的是确定传递到培养箱床垫表面的振动量。对12个带有金属底座的空培养箱和12个带有非金属底座的空培养箱在“关闭”和“开启”状态下的振动水平进行了监测。在两种状态下，两种类型的培养箱均检测到高水平的低频振动。在“关闭”、“开启”和“调整”状态下的几个频率上，金属培养箱传递到床垫的振动明显少于非金属培养箱。这些结果表明，婴儿躺在培养箱中时会经历显著的全身振动。
