I'm struggling to get my head around the two different figures that microphone specifications seem to give.
The first is Signal to Noise Ratio, given in dB. Is a high rating good here?
The other is the self noise, given in dBA - what does dBA mean? And it seems that the reverse is true here, is a low rating good?
Why do some specifications give a Signal to Noise Ratio, while others give a self noise rating? This makes it difficult to compare one mic to another, because I don't know how these two ratings link together?
