The Physics of Electricity

We have enabled listeners all over the world to get closer to their favorite music by making it sound as crystal-clear as possible.

Don’t want to seem like I’m nit-picking or anything but wouldn’t simply clear be mo bettah than crystal-clear....like just cut out the middle man ditch the crystal and go directly to clear. Kinda makes sense eh, or am I missing something ?

>>>>>Uh, Furutech was making a bad pun, aren’t all puns bad?, inasmuch as they were speaking about their “crystal” cable damping technique. 

By the way, Noone has been able to answer my Pop Quiz that asked the question, why do external vibration of audio cables hurt the sound?

Well, it depends who you ask. If you look up Dr Wiki he says the following....which given the currency that defines Dr Wiki's world is pretty well just the bog standard interpretation ( which mostly seem to be variations of you're messing with my magnetic field dude..).

https://en.wikipedia.org/wiki/Electromagnetically_excited_acoustic_noise_and_vibration

https://en.wikipedia.org/wiki/Microphonics

But if one were to present that to the experts in certain patent offices they will say that the effect doesn't exist and all talk about it is just plain hooey.

So pray tell, what are your views on the subject ?

Those 2 links provide good info, unfortunately nothing that answers my pop quiz question that concerns vibration in cables. The first article is not relevant to vibration in audio systems actually. The subject of the first article is electromagnetically excited acoustic noise, which is a horse of a different color.

To whit,

“Electromagnetically excited acoustic noise is audible sound directly produced by materials vibrating under the excitation of electromagnetic forces. Some examples of electromagnetically excited acoustic noise include the hum of transformers, the whine of some rotating electric machines, or the buzz of fluorescent lamps. The hissing of high voltage transmission lines is due to corona discharge, not magnetism.”

Sorry but a bit more confused than normal....the original post spoke of external vibrations not vibrations in cables.

So maybe defining the terms more strictly might be good eh.

Actually the original post (The Physics of Electricity) asked, what makes an expensive cable better than an inexpensive one, does one “conduct more or better electricity?” The mention of Vibrations came later on. Plus there’s another similar thread that asked the burning question, do vibrations affect inert electronics like solid state amps.

In any event, my pop quiz was do external vibrations affect the signal in cables and if so how? It’s very similar to the question why do external vibrations affect solid state amps? I’m going to help you out. What is needed is to first establish what the audio signal in wires and cables actually is and how vibrations could physically or electrically affect it.
