This is something I have always wondered about - does the noise estimation algorithm attempt to use an area of the audio spectrum where no signals were decoded? But I guess a crowded band would make that nearly impossible. In any event, it would be fascinating to hear more details about how the noise power is estimated to arrive at the S/N ratios.
