Noise floor....Is this normal..

[anu_2stroker]

This is the noise floor the UMIK 1 is reading in my room as well as in my car. What am i doing wrong? What can cause this? Uploaded the calibration file in REW.

So i assume this is normal?

I wouldn't say so. Below is one from my desk with the same settings, while the house is pretty quiet. If you open the SPL meter the figures will be in white if the cal file is loaded OK, red otherwise. Set the input volume for the mic to the 0 dB position, which is about 53% (right click on the volume control in the Levels tab of the Windows audio properties for the UMIK to have it read dB rather than percent). What's the mic's serial number?

Can someone post a normal noise floor measurement from a car.. just for reference.

Just and update. Found that noise cancellation was ON in the HP audio controls. However, could not disable it so uninstalled it and tried. No change in measurements unfortunately. Any tips guys..

This is mine from some time ago. I have three refriderator/freezers running, and traffic a few blocks away. I'm in a stick-built house with great room and cathedral ceilings. It's fairly noisy here...

Below is the reading i had taken inside the car with everying OFF. Meanwhile i installed REW in an old PC, getting the same result prettymuch... can it be an issue with the caliberation file?

Cal files for that mic look pretty typical. You can ask miniDSP for their comments by raising a ticket.
