31. Vibration intensity -Measurement 2-

[ 11/24/2017 ]     Labels: 31..Intensity-TopPlate

 
Top-plate's vibration intensity was measured again including tailpiece data.

MEMO:
When the tip of endpin is placed on the floor and restricted to vibrate, the influence seems to extend over whole cello. 


(1)Endpin changes its vibration patterns remarkably.
(2)Tailpiece increases its vibration intensity.
(3)Top-plate slightly weakens the vibration in general or shifts to the flat(/even) vibrations at least along the vertical direction.

Device : Vibration meter VB-8205SD
Cello  : 110-year-old German cello
Endpin : 10mm(D) steel pipe, 28cm below tailpin
Data   : each 10 measurements averaged
