A system where the output loops back on itself and feeds into the input. This often creates a runaway effect. Loops that get bigger and bigger are called positive feedback loops. Loops that get smaller and smaller are called negative feedback loops.
positive feedback loop
The populations keep each other in balance, feedback loops are kept under control.

The amplified audio goes back into the mic and gets amplified again, into infinity, which sounds like this.
