Vibration - What are the Main Sources?


A current thread discussing the best tweaks gave consistently high ranking for component isolation. I am curious to know where all the vibration is coming from that we are addressing with isolation. I understand that high volume listening can create significant vibration, but for the sake of this discussion let's assume we are listening at moderate levels. Can the vibrations from moderate sound levels affect the quality of sound? Are there other common significant sources of vibration that we are guarding against that can dramatically affect sound?

Timely subject!

Getting close to final set up of my TT.

Just made a base - 3/4" mdf "box" filled with sand.

The TT weighs just shy of 60lbs, the base is approx 25lbs

My thinking is this. The vibrations present in the component needs to go somewhere. The vibrations in the environment need to be prevented from getting to the component.

The component should be coupled to something the vibrations can dissipate to. The whole thing should be decoupled from the "world"

So I’m looking to put roller blocks between the TT and the base. It will both couple the TT as well as allow for horizontal movement.

Then, I’m thinking either ISOAcoustics pads under the whole thing, or, springs. So many sources for springs around that can serve virtually any purpose, and are inexpensive. Just need to find springs that are the right diameter (so they are stable), the right height (again, so they are stable) and the right spring rate so the whole unit floats. Meaning, the same force is required to "lift" it as is required to "push" it a given distance.

Seems pretty straight forward...

If floating in zero gravity, and kicking your feet about (not touching anything) vibrations in your body are going to be minimal, all the forces are contained within you. Now, back on terra firma, and you kick the ground, the forces come back into your body. Very disruptive...


I appreciate the arguments against springs and I don’t really know how they work… but I went from spikes on my floorstanders to pucks, to mid- grade springs to expensive (dampened) springs and the improvement kept getting more noticeable. Springs really work @clearthinker
