and you can show that in  that if the  if you add the noise outside the critical band , that doesn't affect the  the decisions you 're making about a signal within a critical band.
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.
