Tweaker456:
We never did any studies on the self damping qualities of Bamboo
during my time in R&D at EAR. It is true that some woods (and MDF)
have lower degrees of resonant behavior. The most important thing
to be aware of is the fact that "damping" reduces resonant behavior
either through extension and compression (extensional damping), or
through shearing (constrained damping). A shelf can be "damped" to
reduce resonant behavior, but damping cannot eliminate shelf vibration
that occurs as a result of being "driven". An audio sound field of
any significance will tend to want to vibrate a component shelf (micro
vibrations). This input energy will both drive the shelf, and excite
it's resonances. damping will usually only address the resonant behavior.
One very simple way to reduce "driven" behavior is to have HIGH mass, which will present a high "impedance" mechanically to the sound field energy. Imagine a thick solid granite component shelf system - it's mass will be so high that sound field energy will have no effect on it, because
of it's high mass. There are lighter (but expensive) ways to eliminate vibrations by using electronic servo controlled platforms that reduce
vibration energy (as used in the optics industry).
