Kal I think you're right. I suppose noise suppression has to baked into the room construction, which of course, mine is not.

My room is professionally treated and one can clearly hear the difference prior to music playing. The room gets into the low 40’s with iTest and low 30’s with the dbMeter app, and I would think the iTest is more accurate with a somewhat decent plug in microphone.
dbMeter does include reference posted below, and in either reading the room IMO is quiet, and not sure if much more would be too extreme.

I used the free dbMeter as well. I didn't have any expectation of it being super accurate considering it's using the phone's microphone. I was impressed though with how sensative it appeared to me. It could detect my breathing.

Room in a room construction. Walls are isolated from building structure. Floor is suspended and vibration isolated. Dual doors with acoustic gaskets.
Most of the residual noise readings are infrasonic. When taking readings you have hold your breath and avoid any movement of clothing. It is a bit like being in a tomb. The biggest shock is when you come out of the room after being in there for some time.

23db is an impressive number especially for an office environment. I think the expectation of background noise is just wired into our brain and we tend to freak out when it's absent. That -9db room has got to be spooky.
