How do I interpret these graphs - noise floor and with rolloff

Do I need to make any adjustments to the recording space before proceeding

Record a short sound test and post it here. Do Not apply any filters or corrections.

Go down the blue links. They’re very short.

There is an analysis shortcut. If you’re recording on the computer, can you tell if it’s on just by listening?

Home readers never pass noise. Studio Silence sounds very alien to most people and they’re shocked what they have to do to achieve it.

I was just wondering if the graphs might reveal something that a listen does not.

If you’re recording on the computer, can you tell if it’s on just by listening?

My laptop is in the space next to the recording space, and (now) under a blanket. Yes, I can still barely hear the fan.
