Do equipment stands have an impact on electronics?
I just realized the topic of this thread is vibration isolation. I love this topic! Why? Because it's so easy to prove or disprove by measuring. But who has ever done that? Well, I did not long ago. Enjoy: http://ethanwiner.com/speaker_isolation.htm |
From Ethan winer's article on vibration isolation: "One fact that isolation proponents miss is sound transmits mostly through the air. Another fact is competent loudspeakers have sufficiently rigid cabinets that don't shake and vibrate very much." Houston, we have a problem. Everyone, quick, fasten your seat belts! |
Tom used the word refracted when I’m reasonably sure he meant reflected. You can see how much or how little the reflection of the laser beam jumps around on one of the walls. This laser reflection method is actually not far removed at all from how LIGO works, inasmuch as in LIGO a laser beam travels down a very long tunnel kilometers in length and is reflected back precisely from a mirror at the far end of the tunnel. Then the laser beam travels back to the original end of the tunnel and the influence of any gravity waves can be seen on an optical screen. Unlike LIGO, however, using lasers on speakers to measure their motion doesn’t necessarily indicate the speaker stands’ isolation effectiveness. The stand could be simply transferring energy to the floor more effectively than nothing at. AND in doing so actually making the sound worse!I agree with your verbiage. As for the word intonate, yes, I did mean to use it. Don't be such a luddite. It can be used to imply conveyance of emotion or emotional content of speech (and not simply pitch). I know its been a long time since you had your intro to English composition in E school....how long ago was it? 55 years? 1961? Is that ballpark? |
Here’s the thing: When someone makes a claim, the burden of proof is on them. It’s not up to me to prove that a 2 volt drop doesn’t have an audible effect. It’s up to the claimant to prove that it does. This is Logic 101. More important, trying to assess the affect of a power wire by measuring the AC power voltage is beside the point. The *only* thing that matters is what happens at the output of the connected equipment. Competent audio gear is immune to small changes in voltage, and routinely filters out the typically small amount of noise riding on top of the power voltage.Welcome Ethan! Thanks for chiming in. Yes, there is a burden of proof to some degree and thus the animus for this thread..... |
