My SPL meter shows ambient/background noise of about 41.x dB. Is that average, hi or low?

Actually, my iphone app is reading down into the teens and lower...  8 db-14db... averaging out at 10db’s...

I wonder how accurate it is.

Sitting here listening now, it’s eerily quiet. Not much, if any, traffic noise outside either due to Covid and we have 2 inches of fresh powder outside which also drastically lowers the noise floor outside of the house.

I can get my iphone db app (however accurate that is) down into the 20’s as well.  I actually have to hold my breathe otherwise my breathing is picked up.  

My room is quiet.  Thats what 12 panels do.  My listening room is a nice place to be even when not listening to music just due to its quietness.

Latenight listening at low volumes is still very satisfying when you are starting from such a quiet background!
