Unlcear about noise making as a useful tactical move
These are the cases where I've used the noise making tactic:


To avoid splitting. If a group of zombies has 2 equally noisy target zones to move to, and you want to avoid adding extra zombies due to splitting (i.e. an odd number of zombies in the starting zone), then making noise clarifies the target zone
As a lure. For example, luring zombies onto a dragon fire trap, luring a group of zombies away from a necromancer who is about to escape, luring a group of zombies into a room to trap them using the lock it down skill etc.
To use towers more effectively. Towers (in the Wulfsberg expansion), allow for archers and spell casters to have more safe shots at zombies. It may be useful to lure zombies towards the tower (to get more shots) or away from the tower (to allow a survivor to escape the tower)
To allow a survivor to escape. Particularly useful when a survivor is in a dead end, or you want zombies to head towards survivors with armour/ironclad skills/regenerate etc.
