Why do plosives or loud signals restore a fickle connection?

I’ve come across this time and time again, but I’m very curious what the actual physical electronic reason is for this. A master fader is missing the left channel, smash up the drum fader and *boom* both channels come back. A reverb send is not working, ask the singer to scream or blow a loud plosive and the reverb starts passing signal again. The cause of these problems would seem to be a poor connection, whether a solder joint or dust or dirt, but I just can’t understand why loud signals will kick these connections back into gear??

It's called the diode effect in electronics. Sometimes contaminants effect transfer of electrons. Then a larger amount needs to gather and build up before the spike can blast through the crap.

The best visual analogy is the San Diego/TJ border crossing when a few hundred people would build up on the other side and then all jump the border at once. Power in numbers.

Clean your switches and connectors.

It's the higher voltage punching through an oxide layer, like on a dirty switch.

For the same reason that saying "Can you hear me now?" on a cell phone restores the signal.

EDIT: Nah, it's probably what one of the posters before me said. Those 'splanations seem to sound more scientifical.
