What you want is a specification that says something like "Self-noise:
-72 dBu (or 0.2 mV). But that's too simple and honest.


That isn't what you want either. The 5dBA figure is much more valuable
than a simple level with no sensitivity reference to compare it to.


Perhaps a figure for the equivalent noise in dBC, so it takes account of
the L.F. noise too?


Far better an unweighted figure and a spectral plot.
