Hmm.
You need to  you need to compare it to something else , what 's happening but it 's what 's happening in the  in the close neighborhood. So if you are making decision what 's happening at one kilohertz , you want to know what 's happening at nine hundred hertz and it  and maybe at eleven hundred hertz , but you don't much care what 's happening at three kilohertz.
So it 's really w It 's sort of like saying that what 's happening at one kilohertz depends on what 's happening around it. It 's sort of relative to it.
