Gee, I almost forgot. The mass-on-spring isolation is more effective for higher frequencies than for very low frequencies, as I got through explaining recently. So, even if springs ring a lot, which they don’t, those higher frequencies wouldn’t make it up through the iso system much at all. A bog standard iso system is at least 99.9% effective for frequencies about 30 Hz. It doesn’t take a brain surgeon 🧠 to see whatever frequencies ringing occurs at will not (rpt not) get through. Not to mention my Phase 2 for the comprehensive plan for dealing with vibration - the use use of effective damping on the top plate, to damp ANY residual vibration from any source. Anyone still not follow raise your hand.

"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 then in the next line... "While it’s actually is true that even the very best isolation techniques do not block 100% of ALL vibrations..."What we have here is universal agreement between both relevant, and one unsuspecting, parties. |
Most anything that isolates, connects at the same time. Springs included. Which of these properties will practically prevail may depend on execution (materials, shape, construction, something else) and it may not be generalized. There may be certain spring that isolates better than certain wood, but it may not be every spring and every wood combination. This is not even physics, it is slightly more than a tunnel vision approach. Kind of a view that many parents try to teach their preschoolers. |
