It helps that all the equipment except for the projector is in an adjacent isolated room, and, that the projector is in a well engineered hush box.

I had never thought of measuring the “no sound level” but did so. Used my Samsung phone and a downloaded app.
Started. Showed 30 db for a minute or so. Then my wife started our dishwasher. Went up to 35 db. And then the church bell started…. Over 40 db…. Then a bike passed through… That’s something different.
In the evenings when listening the background noise is about 30 Db
My Conclusions. 30 db seems to be a very OK quite level and it’s important not to use dishwashers etc when listening even if all our white goods are Miele and Liebherr and selected not just for quality and performance but also for being silent.
The church bells I accept without complaining,

My app doesn’t have A nor C weighting. What is it? It has just “start”.Did you have the app set to A weighting or C weighting?
I see some (too) impressive mesurement here.
You have to realize that phone, by default are very off. The apps needs to be calibrated.
My room is in the basement, fully built to be sound proof ( as much as budget and space allows it) in a very quiet neiborhood.
Using REW + UMIK-1, during the day, i can only go as low as:
33db A
40db C
Using my phone, uncalibrated, I was at:
25db A
30db C
Phones, can give an idea of the noise, but the value are to be taken with a (big) grain of salt.
I wonder if they fixed this with the UMIK-2?Do you have the low level spike problem at multiples of 1 KHz with your UMK-1?
Probably they fixed this issue, but I have read from people complaining about problems with the early UMIK-2 units and need for firmware upgrades.I wonder if they fixed this with the UMIK-2?
Thanks,
