Argh I guessed the OP meant repercussion 1) unintented consequences and 2) re emission of percursion ~= reverberation

While reverberation is kind of just the echo of a vibration.

Reverberation: 2.b. An echolike force or effect; a repercussion: Reverberations from the stock market crash were still being felt months later.

I guess the unintended consequences rather than the physics matter.

Okay, it is a question of taste.

But my proposition works in more than one language (latin included). ;)
