That's way too loud to be safe. Hearing test test the now hearing but not the long term decline & too much too loud kills of the fine nerves of hearing so it can quite easily have long term impacts.
TBH, babies fight because its what they are used to & they don't like change, the Swaddle can be there until it becomes really unsafe in terms of learning to roll, but the noise is something you probably have to bite the bullet like teaching a baby to fall asleep after all they are used to is falling asleep on the breast - ie it will involve tears and resistance, it will involve effort.
I didn't ever use white noise so I can' comment on weaning from it, but I think with noise that loud I'd be going cold turkey on it & even use APOP to get her out of the habit before working on the next step
