Plinth:
Wikipedia. plinth: " A
plinth in architecture is the platform or base upon which a column,
pedestal, statue, monument, or structure rests."
Webster's Dictionary
Definition. Plinth: "A slab-like member beneath a column or pier. "
The
term "plinth" is also used to describe the supporting structure for the
spinning platter of a record player. That is how the term is used here.

Methods of
acoustic dampening within a structure.
(CLD) Constrained Layer
Damping systems are usually used for very stiff structures. A sandwich is
formed by laminating the base layer to the damping layer and then adding a
third constraining layer. When the system flexes during vibration, shear
strains develop in the damping layer. Energy is lost through shear
deformation rather than extension of the material.
Free-Layer or
extension damping: A material is simply attached with a strong bonding agent
or alternately may be troweled on in the case of tar-like damping materials.
Resonant energy is dissipated as a result of extension and compression of
the damping material under flexural stress of the base material.
Vibration Isolation: This method reduces the transmission of vibrational
energy from one system to another. Common isolators are steel springs,
rubber pads or bellows.
