If sound it spread evenly through the same medium, and it will still go through a different one at a different speed, then wouldn't that mean that the sound of every single thing doesn't go away.. the vibrations are just so small that the human ear cannot pick it up.
The reason I ask is that EVENTUALLY that would mean that the sound would continually build up and I think that is the High-Pitched noise that people hear when there is supposed silence.
At least... when I don't hear anything else in particular I hear a high-pitched noise....

They do go away, I think. Think about destructive interference where you have a sound wave and another wave that corresponds trough to peak and the two sounds cancel each other out.

It does. Unlike light, sound depends on a physical medium - usually air. It's the oscillating movement of such a medium that we interpret as sound. Once the oscillation stops so does the sound.

You're confusing frequency with amplitude. The intensity of sound, or amplitude, drops as it radiates in all directions. Eventually, it gets lost in the general molecular shuffle what we otherwise know as ordinary heat.
