I mean sound signal, not physical vibrations through the cable.

 

I was curious to know what you guys think. Please vote, then discuss.

I voted in between. But actually I hope there is no sound passing through your cables as it may affect the signal. wink.gif

Mind you, I did mean the sound signal, not actual vibrations on the cable...

Oh I read that as actual sound traveling through the cable. biggrin.gif

I don't know but optical is probably approaching the speed of light I would imagine.

The only sound traveling though a cable is micorphonics when the cable is rubbing against something.  In my experience, this only applies to IEMs with the cables not over your ears.  Electricity is flowing though the cables to make the driver move to create the sound you want to hear.

I didn't vote because:

In theory electricity current goes with speed of light. Though in reality cables has an impedance which "slows" the signal.

 

Question is either incomplete or asked wrong.

Lol I think you should edit the title of the thread. biggrin.gif

I just updated the first post to refer specifically to the sound signal, not to the physical transmission of sound through vibrations.

The "signal" is the transverse electromagnetic wave that propagates between and around the two signal conductors.

 

Except in a vacuum, the wave will propagate at something less than the speed of light and depends on the construction and materials used for the line (see http://en.wikipedia.org/wiki/Wave_propagation_speed).

 

Actual electron current flow is VERY slow. Literally a snail's pace.

This poll is basically asking whether or not someone has taken a physics class.

I was looking for a good link and didn't find one.  I also needed to confirm what I remember from physics 30 years ago.  It's a popular misconception that electricity is strictly the movement of electrons.

Aw, you're spoiling it. ;)

sub-light?  =p

It ain't faster than the Millenium Falcon, she's the fastest ship in the galaxy!

Speed of sound is something like 340 meters per second.

Speed of light is something like 3 million meters per second.

Speed of electrons is pretty close to the speed of light but not quite.
