How to unlock the Making Some Noise achievement in BioShock Infinite - Definitive Guide
Near the beginning of the DLC when you're on your way to the Silver Fin Restaurant, you'll come across the first lock with blue pins. Hit one of the blue pins and open the door. You can't mess this one up because all six pins are blue. After the door is open, just restart the checkpoint. You'll start right in front of the door and each time the blue pin will count.
As noted by Sergeant JibJab, "you'll come across this lock by reloading the Toy Department chapter."

To obtain a noisemaker you must pick a lock and when the slider moves up and down the cylinder, you must press precisely when it hits a blue pin. You will be picking plenty of locks throughout the game so you should have no problem getting this trophy and should get it early on in the DLC. Just be careful not to hit the red node as that will triggers an alarm. If you want to get the trophy as early as possible, there a checkpoint right before the door where the noisemakers first appear so you can farm them by reloading the checkpoint (credit to Terminator for this tip).
You also must have room in your inventory to collect noisemakers from lockpicks. You can hold 6 in total and if you have a full inventory, the lockpicks you use won't count for the trophy so clear some space to be safe.
