Microphone Background noise level.

Hi,
I have a microphone which I need to determine if it has a fault. I have a .wav sound file which has been normalised in reaper to 0dB. If I emailed the file I need it analysed for microphone self noise and signal to noise ratio. Thanks

Maybe put a link to the file here, so we can hear what the problem is?
