Noise and whole-body vibration measurements were made in a Viking military vehicle to determine the variation that should be expected during repeat measures, the effect of speed (up to 60 km/h in 5 km/h increments), and during travel over different types of terrain (comprising concrete road, gravel track and rough cross-country). Measurements were made at various crew positions (including the driver and commander) in both the front and the rear cabs in the vehicles. Three translational axes of vibration were measured in each seat. Two speeds were investigated over road (35 km/h and 55–60 km/h) and gravel (20 km/h and 35 km/h) surfaces. The effect of varying speed of the vehicle on the measured noise and vibration magnitudes was also investigated. The highest sound pressure level (L_Aeq) of 104 dB(A) was measured at the commander’s standing position during travel over concrete road at 55 km/h. Higher noise levels occurred for a standing commander compared with when sitting on the seat. A maximum single axis frequency-weighted vibration magnitude of 1.0 m/s² r.m.s. was measured on the driver’s seat during travel over track at 35 km/h. Higher vibration magnitudes occurred during travel over track compared with travel over road. Both noise and vibration exposure of crew within the Viking vehicle increased with increasing speed of the vehicle.

在 Viking 军用车辆中进行了噪声和全身振动测量，以确定重复测量期间应预期的变化、速度的影响（以 5 公里/小时为增量）以及在不同地区旅行期间的影响。地形类型（包括混凝土路、碎石路和崎岖的越野路）。在车辆前后驾驶室的不同乘员位置（包括驾驶员和指挥官）进行了测量。在每个座位上测量了三个平移振动轴。在道路（35 公里/小时和 55-60 公里/小时）和砾石（20 公里/小时和 35 公里/小时）表面上研究了两种速度。还研究了车辆速度变化对测得的噪声和振动幅度的影响。最高声压级 ( L _Aeq) 为 104 dB(A)，在以 55 公里/小时的速度在混凝土路面上行驶期间，在指挥官站立位置测得。与坐在座位上相比，站立指挥官的噪音水平更高。在以 35 公里/小时的速度在轨道上行驶期间，在驾驶员座椅上测得的最大单轴频率加权振动幅度为 1.0 m/s ² rms。与在公路上行驶相比，在轨道上行驶时发生了更高的振动幅度。Viking 车内乘员的噪音和振动暴露都随着车速的增加而增加。
