To some degree, Yep.

Whatever the origin of the noise you are hearing in your stethoscope, it is a sign that the material has been set into vibration by the noisy motor or tt bearing. The energy required to initiate the vibration will dissipate itself as heat in the material(s) of which the plinth and armboard are made. The further away you get from the source of the noise or energy, the less energy/noise there is. Also, when the vibrational energy reaches the interface of two dissimilar materials, some of it will be reflected back from the boundary, and some will be transmitted. If the armboard is made of alu and the plinth is made of wood, some of the energy from the noisy bearing or motor will never get to the armboard. This applies to endogenous sources of vibration. If we are talking about mechanical feedback (e.g., footfalls, etc), then the tt as a whole, including the armboard, might be affected in concert with each other.
