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?

I isolated my components by running the speaker wires through the wall to my listening room.  I often say, "Nothing is the best", but this actually is.  Of course, I don't get to show off my stuff, but that is not why I own it.
"zlone" = Corvette or Camaro?

Neither :-). Though loosely related to an engine additive. 
Great discussion, thanks for all the feedback. It sounds like some real results can be achieved with the right solutions. Per my other thread on subwoofer isolation/anchoring I ordered some Nobsound springs for low cost experimentation. I will let you know what I hear. 
It does NOT affect the sound, it is just an annoyance.
Care to explain the logic behind that one?
The author of that article states:

Likewise, I can't bear to hear/ read actual snake oil vendors claiming that you'll get "cleaner highs", "more authority in the bass" or any of the other stupid things you may read elsewhere. The purpose is to stop transformers from growling (usually at no or light load). There is no magic, and it doesn't improve anything other than reduce the acoustic noise from the transformer(s). Anyone who claims otherwise is probably lying.
 Sounds like something you latch onto. Very self reinforcing.

All the best,

@mijostyn,
"Electronics are not effected by vibration. Electrons could give a hoot. If they were we would have F22s crashing all over the place as they are completely controlled by electrons. If we blinded all these silly people they would never be able to tell which devices were isolated or not excepting perhaps the turntable. Silly in the Monty Python sense.
This circus is subsidized by reputable manufacturers who do not want to alienate potential customers, they remain quiet on the subject. Others take advantage of it. Why not? All is fair when it comes to making money.
If people want to spend their money on silly things it is their prerogative and problem. Big Pharma does this in spades."


Unfortunately for some of us, the trillion dollar Big Pharma industry now has governments acting as enforcers.

However when it comes to audio there isn’t a shred of evidence that vibration (or even G Forces) can affect the movement of electrons.

As you say, if you were to believe there was, then you’d probably never board an aeroplane. Or ever get into an electric car. Can you imagine doing 70mph and all the electrics suddenly decide they’re not playing ball?


I’m guessing some of us might be wondering about the relationship of vibration and mechanical transducers eg cartridges, tonearms, turntables, loudspeakers (headphones and microphones) etc.


Surely this an area where designers with advanced measuring resources are better equipped to find answers and solutions, if they’re needed, than we are?
On the other hand it seems harmless enough to experiment with bits of sorbothane/rubber pads and a few springs under your loudspeakers if you feel that environmental resonance is high in your location.


Where I live (a 100 year+ old house with wooden floorboards just yards away from an increasingly busy main road), every now and then I can almost feel (as well as hear) the sound of a heavy vehicle as it passes by outside.


I always felt that my turntable sounded best on a light rigid wooden table than any of the wall shelves I tried.
I wouldn’t be surprised to discover that, apart from perhaps very late in the evening, the entire house was in a constant state of gentle resonance caused by the traffic.
