Vibration isolation or absorption?

Max once said “ Any material or device you put under any piece of equipment will change the sound”. Sometimes for the better, sometimes not.

Some things I have found to work:

Townshend Platforms, Ingress cup and balls, slate, very slightly inflated tyre inner tubes, springs, a combination of these.

Do you know the acoustical tiles people put in their ceilings, and on the wall. They’re about three or four dollars for one square foot piece.

These are excellent absorption panels and they fit real nicely underneath certain speakers and other components. And what’s really cool about them is that you can easily slide the component around, and the speakers can slide a around to if the footprint isn’t too large.

How’s that for solving the vibration problem?

Dubious. 🤣

absolute mechanical isolation and decoupling cannot exist in the presence of gravity

You throw this out there to further your self-serving post, intimating that because absolute decoupling is impossible, your way is the only way.

Absolute decoupling is not achievable and not necessary! A resonant frequency of the decoupling device at about 3 to 5Hz will prevent transmission of any musical sound. The rumblings from a nearby volcano might get past the device but then I think you may have bigger problems 🙄

Spikes couple and couple well to a surface and will efficiently transmit vibration in both directions. 

Can you provide examples of which firms do mechanical grounding Products?

Hello, jumia,

Not many of us have the patience and capability to apply the correct geometry and material science formulas for audio products. Unlike a spring, absorption puck, or damping wafer, these designs take a lot more research, development, and testing before becoming recognized by the public as a tell-all product.

Companies using mechanical grounding technologies are the minority compared to the isolation, decoupling, and energy absorption versions in today’s marketplace. 

When AudioGon opened for business, we announced the first equipment rack designed to vibrate. It took five years for people, the naysayers, and the press to use and recognize the technology we innovated. 

AudioGon had no moderators during those times. I was ridiculed, called stupid names, and took everything the members dished out. In my opinion, the High-End Audio Industry is hesitant to accept change or new advancements in technical achievements until there is advertising money involved.

We knew it was only time until the products would speak for themselves and lead the Company. Now, we are the oldest surviving vibration management company involved in audio.

Our Cello and Acoustic Bass End Pins took twenty years to develop and market. The first racks,  known as Sistrum Platforms, took ten years, and the Rhythm Platforms required fourteen years to advance performance. The Energy Room took twenty-five years to manufacture, and Live-Vibe’s first offering, the Audio Points™, took six years of testing, shaping, and beta listening. 

Goldmund is a European counterpart that uses mechanical grounding in all their electronics and speaker designs. They spent the time required to develop a highly respected line of products and show how mechanical grounding provides a higher sonic outcome.

Shun Mook was another of the earliest companies in this country to understand and adapt mechanical grounding techniques to their equipment offerings.

These are a few of the companies that adopt and expand mechanical grounding technologies. We are outnumbered in the isolation-decoupling department as there are hundreds of these to choose from.    

The term mechanical grounding, associated with parts and equipment chassis’ is another word for direct coupling.
