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?

Springs add another boundary layer and introduce more interfering energy. The motion artifacts of the springs and resulting inertia when driven by the voice coil of a speaker need to be overcome by the voice coil. If you suspend all speakers from either above or below you have the same retention of interfering energy. And so is your sound.

Boy, are you confused. The isolation is achieved by the combination of mass and springs. That’s why LIGO uses many mass-on-spring devices. That’s exactly how they were able to achieve results. If there actually were ARTIFACTS they wouldn’t have been successful. Say, whatever happened to the Seismologist, you know, one that presumably knew what she was talking about? If she was smart she grabbed a hat a long time ago.

That, in and of itself, says everything.

Eggs ackley! There’s the high end and then there’s everybody else. Talk amongst yourselves. Smoke if ya got em.

Hey agear, biology joke: bacteria is the only culture some people have? Get it? 😁

One more: The only culture you got at UVa was through osmosis. 😀
Geoff,
Those springs help develop and help retain shear wave interference. The fact that a moving coil sits atop a moving object (your perpetual motion machine at least in motion while you are trying to listen to music in accurate formation and time) I guess you could move your head in the opposite direction in hopes of keeping perfect time and speed ..kinda like a woodpecker..He's got it going....some Doppler distortion as well.

"Geoff,

No they don’t. The combination of mass and springs attenuates the structural vibration, ALL structural vibration, whatever its source. Vibrations that reside on the top plate or anywhere in the device can be dealt with by any number of means, as well they should.

The motion of a spring based isolation device is minuscule compared to any motion of the voice coil or the speaker cabinet. You can therefore IGNORE the motion of the isolation device. In fact, there isn’t any motion you can detect visually, duh! The motion is damped by the inherent or intentional internal damping if the device. It’s probably, what, maybe a thousandth of an inch. Besides, the isolation device can only move with only ONE FREQUENCY - it’s resonant frequency. Hel-loo! There is not MORE distortion. There’s LESS. There’s less distortion because you’ve reduced the amount of seismic vibration getting up into the speaker or whatever. Of course for speakers the added BONUS is that the mechanical feedback of the speaker to the electronics and cables is reduced. You know, by decoupling them. Thus, LESS DISTORTION.
