I have a set of questions regarding understanding graphs I am well aware these have been presented and explained many timesbefore but I just can't wrap my head around some basic questions which should in essence catapult me as I am stuck on simple thoughts. I just want to know when looking at the waterfall graph we can see the particular frequencies take its time to drown out in the room(that I understand) such as the example given in the picture below at 180hz in red. But looking at the 40hz to 50 hz is that decaying longer than the 180hz? I am trying to understand more about that bubble at 40 to 50 and the one at 15 to 25 as it rises with a flat part splattering the page, not sure what that exactly means? Is that decaying significatnly longer? And how do i read what the decay time is what am I looking at?
Secondly can someone give me some of the limits or parameters or what to do in the controls to read a step response clearly, I cant seem to get a view of it properly.
