This type of measurement is not affected by flow rate or external vibrations.
Weber, who initiated experimental searches in 1960, used a freely suspended massive bar whose suspension is isolated from external mechanical vibrations.
Instead, it relies on a newly developed material that, by virtue of its inherent non-resonance, absorbs external vibrations.
In fact, studies using external vibrations to create proprioceptive errors in movement show that Parkinson's patients perform better than healthy people.
It cuts out the external vibrations and allows the augmentation of others.
Active vibration control is the active application of force in an equal and opposite fashion to the forces imposed by external vibration.
This makes the method much more insensible to external vibrations and noise.
And external vibrations are kept at bay and rendered harmless by floating the turntable elastically within its frame.
"Then they cannot receive and interpret external vibration."
