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?

To Bdp24,

Not to sway this thread off topic but as an experienced percussionist you might find this interesting:

My background was a touring sound engineer through the seventies and eighties spending a lot of time working with percussion instruments, the piano being my favorite. I learned from musicians who graciously took the time to educate me on multiple playing techniques, pitch and tuning procedures. Upon retiring I could also differentiate the sonic characteristics between the many name brands of instruments as well.

The company I now work for continues to engineer products that improve the operational efficiency of a variety of musical instruments that come in contact with the floor, providing newer, more efficient mechanical grounding (direct coupling) methodologies ala Star Sound style.

In our opinion, current drum and cymbal stands relate to resonance function described as a “catch and hold” methodology. They hold the energy within the metals then releases it back into the air as heat via frequency cancellation. The rubber feet also assist with primary absorption in reducing the resonance formed from vibration. This process has worked well over the ages but we are discovering performance can be improved.

Our technology is titled Live-Vibe Technology™ which utilizes an optimized geometry, coupled with material science and mechanical grounding techniques. In every case involving prototypes or where the technology has been adapted to existing products specific to musical instruments, the sound definitely improves moreover, without altering the sonic character of the instrument.

Example: When you adapt Audio Points™ to a Musser®  vibraphone with or without a variable speed motor; the instrument immediately responds noticeably with greater dynamics, improved attack and, more importantly, lengthier decay times. The vibes also increases in volume and stage presence - all with a sense of effortlessness. Each of these musical attributes coincide with our highly successful Tone Acoustics Endpins™ for cello, upright bass and bass clarinet. We custom manufactured a set of Audio Points and mounted them to a concert grand piano; that experience, both stunned and lifted us to a new musical level of thinking.

We are convinced that possibilities exist to improve overall performance on a drum kit by designing and improving the stand builds. We base this assumption on the proven success of the Original Sistrum Platform™ leg assemblies. These assemblies feature three materials which were used in combination to move energy to ground at high speed. This technology literally brought the equipment rack design to life. In addition, we had success in modifying and/or building microphone stands that produced a much clearer, smoother warmth with a greater, airier highly-audible response with a variety of newer and classic microphones.

I met a percussionist in Allentown, PA who owns a machine shop and manufactured snare hardware using copper and brass as principal materials modifying a Slingerland deep snare shell. The drum sounded like a live gunshot with absolute over-the-top volume. Unfortunately the snare overpowered the rest of the kit and actually limited the override microphones capabilities to enhance the cymbals and kit; however, we learned from that experiment where materials that are highly conductive for resonance definitely have a profound effect on the overall performance specifically in the speed of attack, stage presence and dispersion and provided a much deeper (lower frequencies) sound quality.

Why not focus on the drum shell too? By establishing a greater operational efficiency to the instrument’s materials construction, forming a high-speed conductive pathways for resonance transfer we might soon be tuning drum heads on just three pins instead of multiples.

From a vibration management perspective, I am constantly amazed how the world of hi-fi components, loudspeakers and studio environments continue to integrate seamlessly with our understanding of musical instruments.

Thanks Robert, I'll look into your products. Some of the drum company's have introduced accessories designed to allow their drum shells to resonate as long as possible (sustain is very "in" right now in drums), by suspending their mass in free air. Mounted toms holders are no longer mounted directly on the toms' shells (metal parts bolted onto drum shells seriously affects their ability to resonate), but are instead attached to the drumhead hoops. Pearl offers rubber feet for floor toms legs which contain an air pocket designed to prevent the shell from being "grounded" to the floor, robbing it of it's full vibrational resonance.

For hi-fi product support, isn't a lack of resonance the goal? And whatever resonance (vibration) is inevitable to be prevented from entering hi-fi components? Absolute isolation may be an unreachable goal, but it's a correct one imo. 

I use Robert and Star Sound on every piece of my equipment tt,phono amps, power supply,conditioner,trans, dac ,spkrs, stand and subs.Works like a champ ...my stand is filled with micro bearings ,the points are rock solid .let it vibrate ! jmho

Shear waves do not travel thru the air so they cannot be a part of your acoustic waves...

That is correct.  They do propagate in any fluid, only solids.  The guy arguing with you above is completely wrong.

As side from the obvious grammatical errors in your statement, "they do propagate in any fluid, only solids," any wave can propagate through a solid OR fluid. That is why we have shear waves and shear forces in air. And why there are shock waves in air. Apparently you fellers don’t know the difference between a force and a wave. Acoustic (sound) waves - the ones that travel through air - are mechanical waves, just like waves in solids. And sound waves travel through heavier liquids like water and even solids. In fact sound waves travel faster through heavier liquids and solids than through air. And that’s why, in terms of their effect on components, insomuch as they are mechanical waves, acoustic waves produce vibration in components. There is no difference - in terms of their *effect* - between the vibration produced by acoustic waves and the vibration produced internally by transformers, motors, etc. I consider this particular case closed.
