Imagine a giant Alkaseltzer tablet. Lots of noise to confuse passive homing and lots of bubbles to confuse active homing. At least, that's how they worked 30 years ago, but I can't imagine that they're much better now because the basics of fooling a torpedo are pretty much the same today. The torpedoes are smarter but they perceive their environment in the same way.
>noise maker can't stop a ping form the warhead can it?
Yes, it can. Ping an air bubble, see an air bubble. At least, that's how it was thirty years ago. Things have probably changed a bit since then but I'll bet that the difference isn't significant. Sonar has been a mature technology for a while now.

Actual maneuver (again, 30 years ago) was a snapshot down the bearing of the incoming torpedo, dial up a flank bell while doing a 180, usually get on the other side of the thermocline (depending on local conditions), and then run like hell while looking for an opportunity to get out of its search cone. You're probably not going to run a modern torpedo out of fuel in a straight chase, but reducing the closing speed gives your more time, which gives you more options and chances to confuse it.
The problem (which I didn't realize at the time) is that this is mostly hypothetical. If we ever get a war with modern submarines trying to kill each other, I'd expect that we're going to learn a few things that no one had thought of.
