I try not to make noise on purpose when ice fishing, but noise is made none the less. Augers are loud, sleds are loud, walking is loud, and yelling FLAG is loud. Pike seem to like some vibration, like vehicles idling or a radio, or stuff like that. We were pike fishing with tip ups a few weeks ago and had the truck running. Every time the cooling fan would kick in a flag would go up, no joke. We tried shutting it down and starting it and that kind of worked too, but not like the cooling fan, that was magic. I have driven near/past tip ups and had them go off with a fish. Walking around doesn't seem to do as much.
As far as the rattle baits, I have rattle traps and I can hear them clear as day through the aluminum boat. I can hear the strike before I feel it. I can also feel the pike following a few inches behind the bait because the weight on the rod is less. I usually give a good jerk, like the bait is trying to get away, or maybe go into a turn, and they do the rest.
I have had pike hit a spoon right next to the trolling motor and a friend of mine says his dad used to run the boat in circles on a slow day to get pike to bite. He swears it worked. I have held position in fast water/rapids with an outboard while fishing with a friend and we have pulled fish after fish out of the water not more than 20 feet from us while making a ton of noise.
