Make sure the steam wand is in the milk when you turn it on and then only just barely bring it out to aerate. You want it to be as quiet as possible.

Make sure when you start steaming, the steam wand is fully in the milk, and go slowly! If it's splashing, you're probably pulling the wand too far out of the milk. Pull the pitcher down slowly until you just barely hear the aeration/"paper shredding" noise. As for when you put the pitcher down, make sure the wand is to the side of the pitcher a bit, so its creating a whirlpool, not just splashing to the side.
Other than that, make sure you aren't overfilling or underfilling the pitcher. Good luck!
