46e. Vibration beat--B(496Hz)--COMPARISON--Top plate--

some fandamental B(491Hz) beats were missing

Note:

The duration time of the vibration of B(491Hz) note on cello A string after a pizzicato, like other notes, was following order: top plate > endpin > lower-bouts.

In these measurements, sometimes some fundamental B(491Hz) beats were missing.
This phenomenon is very similar to the 'wolf-tone'. The impacts/influences on sounds are currently unidentified.

(高音のA線上のH音-491Hz-、ところどころでウルフトーンのように基本振動の欠落が見られた。どういう音響影響があるのかは不明。)
