There is a free app called VibSensor that runs o= n both android and I-phone/pad platforms.=C2=A0 Although not a research qua= lity system, running the app and holding the device firmly against a surfac= e of interest will give objective results.=C2=A0 This may give a basis for = useful comparisons for the terminally curious.

In my case, dynamically balancing the MT prop and the flex = plate-damper combination as separate units made a noticeable difference in = the system vibration signature.
