dc.descriptionNeonatal infants in need of advanced care, often require transportation via road ambulance to neonatal intensive care units. The ambulance exposes these vulnerable infants to potentially harmful noise and vibration. To better understand the levels of vibration, this paper maps the magnitude of acceleration due to vibration throughout the cabin of an ambulance. By developing a better understanding of the distribution of the vibration magnitude, decisions can be made to determine the optimal placement of the neonatal patient transport system. Using an inertial measurement unit to measure the translational acceleration and angular rates of the vehicle during on-road testing, the equivalent acceleration at any point in the vehicle can be determined, assuming rigid body motion. It is observed that the distance away from the vehicle’s centre of gravity increases the amplitude of acceleration. For a relatively smooth section of road, it appears the placement of the neonatal transport system has minimal impact on the acceleration magnitude. This indicates that the frequency-dependant compliant motion of the transport system, in combination with the placement, likely determines vibration level.
