Do equipment stands have an impact on electronics?

Mechanical grounding or isolation from vibration has been a hot topic as of late.  Many know from experience that footers, stands and other vibration technologies impact things that vibrate a lot like speakers, subs or even listening rooms (my recent experience with an "Energy room").  The question is does it have merit when it comes to electronics and if so why?  Are there plausible explanations for their effect on electronics or suggested measurement paradigms to document such an effect?

Unless the device is properly grounded it will suffer from shear wave interference and the resulting inefficiencies..even if it floats in air. Tom

No it won't. That's what damping is for. By inspection the frequencies of acoustic waves are well above seismic frequencies, which are not amenable to damping. Case solved.

Shear wave interference. Wow! Did you think that up all by yourself? The resulting inefficiencies? Groan.....

Shear waves do not travel thru the air so they cannot be a part of your acoustic waves.. Shear waves are part of how a speaker operates as well  as that of a vinyl record and the stylus that tracks that record. Removing or reducing a polarity of  shear will increase the operating efficiency of a device and in the case of audio make for better sound. Tom. Starsound Technologies

if you're not referring to vibration or acoustic waves traveling through the air and producing vibration then you have discovered a new science. Congratulations.

Thanks Geoff,

There are a couple more besides me.
It's always been there.
