But , if you  if you  if you modulate the noise , the masking goes up and the moment you start hitting the  another critical band , the masking goes down. So essentially  essentially that 's a very clear indication that  that  that  cognition can take uh uh into consideration what 's happening in the neighboring bands. But if you go too far in a  in a  if you  if the noise is very broad , you are not increasing much more , so  so if you  if you are far away from the signal  uh from the signal f uh the frequency at which the signal is , then the m even the  when the noise is co - modulated it  it 's not helping you much.
Mm - hmm. Yeah. Mm - hmm.
Hmm.
So. So things like this we are kind of playing with  with  with the hope that perhaps we could eventually u use this in a  in a real recognizer.
