Hmm.
Unless this noise is modulated. If the noise is modulated , with the same modulation frequency as the noise in a critical band , the amount of masking is less. The moment you  moment you provide the noise in n neighboring critical bands.
Mmm.
So the s m masking curve , normally it looks like sort of  I start from  from here , so you   you have uh no noise then you  you  you are expanding the critical band , so the amount of maching is increasing. And when you e hit a certain point , which is a critical band , then the amount of masking is the same.
