There is a free app called VibSensor that runs on both android and= I-phone/pad platforms.  Although not a research quality system, runni= ng the app and holding the device firmly against a surface of interest will= give objective results.  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 combi= nation as separate units made a noticeable difference in the system vibrati= on signature.
