Does anyone use wood for vibration control?

geoffkait,

Your last post appears to be worth thinking about. Emphasis on word "appears".

Those two statements are not contradictory. They are so removed from reality that they are really not funny anymore.

Have you ever gotten a chance to consider that there is no such thing as audio signal? Misnomers abound around here, but everybody and his brother knows that what most like to call audio signal is vibration. Even many sisters agree.

geoffkait,

"...of whether tis better to let vibrations roam free and unfettered or to try to harness and constrain them."

I see that you are switching from annihilation of vibrations ("dead vibrations are only good vibrations", or whatever cutesy it was) to using them with certain control.

Inconvenient news is that you are slightly behind. michaelgreen has been on that path first.

Maybe you should go over to TuneLand for a little bit. I see you've come around.

Like Robert at Star Sound Michael Green believes that there is no such thing as isolation. I.e., you cannot prevent vibrations from coming up from the floor and interfering with the electrical signal in electronics. Furthermore, Michael believes that the electrical signal itself is vibrating so why bother trying to prevent external vibration from reaching it. I believe Robert at Star Sound used to say (before he and his trusty sidekick Tom fell off the face of the Earth), “There’s no such thing as absolute isolation.” Which sounds a little like a quote from Alien or Prometheus. I suppose he was trying to say since it can’t be absolute why even try. Or some such nonsense. But I digress.

While it’s actually is true that even the very best isolation techniques do not block 100% of ALL vibrations, even reasonably good isolation techniques are extremely effective in blocking most of them. For a modest iso system with isolation in the vertical direction, the device will be at least 99% effective for frequencies of vibration above 20 Hz. And percentage blocked is 50% at 10 Hz. Follow?

One irony of course is Michael promotes using springs. Apparently he did not get the memo that springs with mass on top is the very definition of an isolation device. But maybe I misunderstood. Maybe he’s placing springs on top of things. 😬
