WebThe passive vibration control can be realized by using tuned vibration absorbers, tuned mass dampers, linear and nonlinear vibration isolators. Vibration isolation, as one of the most commonly adopted vibration mitigation methods, prevents vibrations transferred to an object by isolating the object from the source of vibrations. WebTo better understand the influence of passive and active control groups on cognitive interventions, we conducted two meta-analyses to estimate their relative effect sizes. While the first one broadly surveyed the literature by compiling data from 34 meta-analyses, the second one synthesized data from 42 empirical studies that simultaneously ...
