Yes, measurements can provide information. When measuring it is the combination of the specific component on the platform that counts. Whatever you set a component on will change the resonance frequency of both objects. Vibrations at the resonance frequency of the component will increase the amplitude of vibration in the component. Multiple frequencies of vibration impact the component simultaneously and no single material (wood, whatever) is capable of handling multiple frequencies in terms of both damping and isolation. Thus the frequent use of constrained layer construction with a multi-purpose design: impede external vibration from entering the component (for example, from the floor) while providing a mechanism for vibration within the component to convert from mechanical energy to heat.
Imo the final proof comes with listening.
