Whole-body vibration (WBV) affects heavy mobile machinery operators and is a significant health risk for 7% of the workforce. Vibration exposures vary between industrial environments, for example between mining and forestry environments. Industrial seats are one engineering control measure that can effectively reduce vibration exposures, but we have observed that individual seats are best-suited to attenuate WBV in specific vibration environments – they do not work optimally in all applications. I developed a seat selection algorithm for matching seats with vibration environments within my last Discovery Grant. However, the seats are merely one component of the complex workplace environment. Vehicle operators frequently adopt awkward postures, such as neck and trunk rotations, in order to gain the necessary field of view to safely operate the vehicle. Posture directly influences the transmission of vibrations through the body. For example, spinal posture influences the biodynamic responses such as apparent mass and the seat-to-head vibration transmissibility.

全身振动（WBV）会影响重型移动机械操作员，并且是7％的劳动力的重大健康风险。振动暴露在工业环境之间，例如采矿环境和林业环境之间。工业座椅是一种工程控制测量值，可以有效地减少振动暴露，但我们观察到，在特定的振动环境中，各个座椅最适合减轻WBV - 它们在所有应用中都不最佳地工作。我开发了一种座椅选择算法，用于在我的上次发现赠款中与病毒环境相匹配的座椅。但是，座位只是复杂工作场所环境的一个组成部分。车辆操作员经常采用笨拙的位置，例如颈部和躯干旋转，以获得必要的视野以安全地操作车辆。姿势直接影响振动通过人体的传播。例如，脊柱姿势会影响生物动力反应，例如明显的质量和座椅对振动的传播。
