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?



** The ear is very insensitive to low frequencies at low SPLs - so using the A curve is appropriate for condenser mic self noise when used for general music and speech applications.

Dynamic mics have self noise that increases steadily as the frequency rises, cos it is white noise - very different to the pink or red like noise externally polarised condenser mics generate.
