Vibration Frequencies of Audio Gear?

Posted by aggielaw on April 13, 2017 at 17:33:15:
Hi there fellow inmates! First post in many years here. I hope you are all doing well.
I've been researching constrained layer damping systems in order to build three three-shelf racks for my equipment. I have seen the now nearly 15 year-old DIY Symposium thread, but there have been many advancements in polymers since then, and I'm not sure the formula I saw was close to optimal.
Although CLD systems can be constructed to cover a wide range of frequencies, I think one can only achieve a superior solution by knowing the vibration frequency or what he is trying to damp (or get incredibly lucky).
With all that as background, I'm looking to damp a CD player, a turntable and its stand-alone motor, a couple stand-alone power supplies, and a DAC. (See how old I am? I used an Oxford comma behind "supplies!") ;)
Can anyone give me insight in to the vibration frequency of such devices? It would help tremendously my choosing the viscoelastic polymer for my shelves.
Any other advice or experience you are willing to share about CLD systems for audio component shelving is greatly appreciated.
Many thanks for you help!
Best,
HC
