How to isolate turntable from footstep shake or vibration

I am sure there are turntables less susceptible to footfalls. But, the simplest solution is to remove the tt from the trampoline. 

I had an AR which I could rap in the the top with my knuckle and it would not skip or have the sound transmitted to the speakers. It did what it was designed to do. When I walked by it would skip every time. The solution was simple, a wall rack… that is the solution for suspended floors.

I couldn’t agree more. Learning how to learn… I have been very lucky.

”Engineer you say…”.

I was trained as a scientist. I got out of school and needed to get a job to buy a suit and get money to move and look for a job in my profession. I was working at a start up company as a manual laborer. When equipment would break I would run over and fix it and recommend how to change it… I was board to death. The owners saw this and hired me to architect and build a prototype of a new system. I am not a stereotypical engineer… I know I have worked with hundreds of them at corporations like Texas Instruments, Sharp Corp… and others. A good way to become frustrated at getting anything done… they have to re-invent everything and make it perfect. Scream 🙀!


I worker at Burr-Brown Corp for 15 years. Don’t know if you recognize the name.. DACs, op amps, and ADCs used in high end audio. Yes, with the exception of one of them, they simply don’t believe in a difference in sound possible or their circuit could sound different… and as a consequence refuse to hear it.

First thing I learned out of college. Got a job as electro mechanical engineer. I needed to have a perfect gripping material to coat a rotating drum that was to pull fiberglass. I got out my calculator and tables of coefficients of friction. After a couple hours in the books, I realized I was getting no where. I quickly fabricated a little drum with motor, and went out and bought every brand of PVC tape, adhesive, and Saran Wrap I could find. Then just wrapped the drum and tried it until I found one that worked perfectly. Then I built a 10’ high drum and used the material I found by quick trial and error. A couple years later got into audiophilia… where I quickly learned peak wattage was meaningless… and the watts RMS was nearly so… and that I must try interconnects and power cords in my system. It’s a good lesson to learn. 

I think it is a bit dependent. One usually prizes perfectionism in a brain surgeon but not in a good manager. I am very pragmatic and can vary my precision based on the task at hand. I my way to the executive level in Corporate IT, so had to deal with many perfectionist programmers that would never finish anything.  My best friend is a perfectionist and has spent his life struggling to keep his head above water. He tried to be a Doctor, but just didn’t quite make it. Growing up with him I always felt inferior, I now look back and feel very sad for him… it can be like a disease.

The springs in the turntable are to isolate the turntable from higher frequency noise. Not footfalls and subwoofers. Typically the solution on floating floors  is to decouple it from the floor and use a wall mounted turntable shelf.
