Calculate mic noise into dBA from mic data
Author: Göran Nilsson
Date: 02/28/2014
Can anyone tell me how to calculate

1.)
The mics noise in dBA (or dBC or whatever) from mic data.

I mean that the mics own noise (without signal)
must be the same as some ambient noise signal.

Put the mic in a absolute quiet room.
Measure the mic signal (mic noise).
Now add some ambience untill the mic signal
has increast by 3dB.
What is that added ambiense in dBA ?

2.)
The same calculations for a mic pre from data
relative to a mic (mic data).
