vibrations are generated by transformers (most often) ... springs will return vibrations back to the device (they cannot suck and weaken them) ... MС understood this and shot himself))
Have you ever solved a high end audio issue using non-audio technology? Or, visa versa?
Sometimes we just have to be creative to fix a problem. Our "bag of tricks" may go well beyond the usual "audiophile grade" tools of the trade to produce a positive result.
Here's one:
Years ago, I acquired a little British sports car. This, itself is an unusual story. I'm a performance car enthusiast with a 835HP vehicle is parked in my garage.
At any rate, the little 4-cylinder "tractor motor" had solid lifters that sounded like a Singer sewing machinegoing down the road above 3,000 RPM. It distracted from the driving experience. I was thinking how nice it would be to quiet them down a little.
Then I remembered the can of Acoustical Magic material I had in the basement. For those unfamilar with this material, it's used to dampen the vibration/resonance of turntable platters. I pulled the aluminum valve cover, cleaned and degreased it thoroughly, then applied a generous portion of Acoustical Magic. After a little curing in the oven and allowing it to set for 24 hours, the valve cover was reattached.
If I had it do over again, I would have measured before/after with a spectrum analyzer. But, my best guesstimate is that there was a 6-9db drop in the tapping sound, and I could hear the sounds around me while cruising. The driving experience improved exponentially. Thanks to Acoustical Magic for a cheap, effective solution to my "acoustical" problem.
I have to admit that a year later the true "hot rodder" in me required that I add a turbo to the little engine. The sound of the off-throttle blow off valve is music to my ears. And, driving something resembling a real sports car, as opposed to a British commuter car was a plus.
