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）影响重型移动的机械操作员，并对7%的劳动力构成重大健康风险。振动暴露因工业环境而异，例如采矿和林业环境。工业座椅是一种可以有效减少振动暴露的工程控制措施，但我们观察到，单个座椅最适合在特定振动环境中衰减WBV-它们并不是在所有应用中都能发挥最佳作用。我开发了一个座位选择算法，在我最后一次发现补助金中将座位与振动环境相匹配。然而，座椅只是复杂工作环境的一个组成部分。车辆操作者经常采用笨拙的姿势，例如颈部和躯干旋转，以便获得安全操作车辆所需的视野。能量直接影响振动通过身体的传递。例如，脊柱姿势影响生物动力学响应，如表观质量和座椅到头部的振动传递率。
