Hi Donnie,
All single materials when used on their own will resonate or ring and add artificial artifacts to the signal the system is reproducing. Natural wood or acrylic have strong resonances, stone and other rigid materials will store mechanical energy and release it over time (ringing) which results in contamination.
The most effective method would be to combine layers of specific materials so that the entire shelf will mitigate the individual resonance of each material and be self-damping.
