I think what they were saying was that , um , for this next test there 's gonna be some of the cases where they have the same type of noise as you were given before hand and some cases where you 're not.
Like  Mm - hmm. OK.
Mm - hmm.
So , presumably , that 'll be part of the topic of analysis of the  the test results , is how well you do when it 's matching noise and how well you do where it 's not.
