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?

If you recall you were the one who demanded I discuss Morphic resonance. In fact you insinuated I was dodging your questions. You can’t have it both ways, silly. OK, you can proceed with your troll thread.
Yes, and the information received is not helpful due to its very nature.  Next.
What is the difference between a hypothesis and a theory? | CARM https://carm.org/difference-hypothesis-theory
A hypothesis is an attempt to explain phenomena. ... A theory is the result of testing a hypothesisand developing an explanation that is assumed to be true about something. A theory replaces thehypothesis after testing confirms the hypothesis, or the hypothesis is modified and tested ...


No they are not the same thing. A readily accepted and thoroughly tested hypothesis becomes a theory. Of course you had to try to deflect to something else to avoid the point of the post. Pretty typical. Google sure is a great thing. Pretty much every reply to the query said the same thing, but you knew that, didn't you? When will any of your products ever get to the point of being a theory instead of a guess?
Somebody was sleeping the day they taught that an hypothesis IS a theory.
Wow stop showing your hand there.   Must be an off-day.  





Okay, okay.  We all have to admit that Geoff is an evil genius and that his entire routine (and business) is a prolonged, Monty Pythonish spoof of the industry.  Well done.   We are all fools indeed and deserve such treatment.

Mr. Kait states: - The only way you can possibly deal wih seismic waves is to decouple the component from them, and I'm referring to rotational (bending) forces in additional to the usual vertical forces and forces in the horizontal plane.

To which Audiopoint responds,

"Your springs are actually functioning as a “direct coupling mechanism”. Depending on the actual materials and dimensions of springs used, the speed of the resonance transfer will vary as will the bandwidth of frequencies across the audible and inaudible spectrum, yielding different sonic results in comparison. Frequency and Speed with springs is complexly related to the mass and mass distribution of the component. We too have used springs in our studies and development processes and have found that there are too many variables in each possible usage scenario; there is no “one-size fits all” with spring coupling. Ultimately, you are ‘NOT Decoupling’ with the use of metallic springs - try another material."

if it weren't so funny I suppose it would be sad but let me clue you in to how springs actually work, not as couplers as you surmise, but as Isolators. It all has to do with what I've been referring in my posts on this and related threads to mass-on-spring isolation, which is the physical principle on which almost all vibration isolation devices are based. Mass on spring isolation requires both springs and mass to accomplish the isolation. The isolation is noted by attenuation of structural vibration according to the characteristics of the low pass mechanical filter, analogous to an electronic filter we are perhaps more familiar with. The mechanical low pass filter behaves such that the roll off of structural vibration begins around the resonant frequency of the iso device. The effectiveness of iso increases with frequency as you would expect.

The mathematics of mass on spring isolation is very simple. It is represented by the equation, Fn = square root (Rs/m), where Fn is the natural or resonant frequency, Rs is the spring rate of the device and m is the mass (load). If there are 4 springs the total spring rate is 4 times the spring rate of an individual spring. That's why my first iso device, the sub Hertz Nimbus, has only one spring: to reduce spring rate and thereby reduce resonant frequency.

There is more to vibration isolation but that's the fundamentals. So, to summarize, springs are not really couplers. They're Isolators. That's precisely why the LIGO project was finally able last year to detect and observe gravity waves the amplitude of which are on the order of the diameter of a neutron. It's because the springs in LIGO's vibration isolation system prevent seismic type vibration such as Earth crust motion from interfering with the optics and electronics of the LIGO detectors. It's the same concept that audiophiles use to prevent seismic type vibration from interfering with laser assmblies, tonearms, stereo cartridges, printed circuit boards, etc. by incorporating mass on spring isolation.
