Once you have tuned your ears to this noise, you can't let go of
it.  It's everywhere, on all recordings and you feel like a fool: "How
could I ever feel proud of my old recordings?"

Thanks Klas.  I've just started and I've already developed this
particular sensitivity.  So it  does go with this territory.-LOL

In an attempt at some self-noise mittigation, I've done some rig self
noise tests for each of the relative recording level marks, with each
mark recorded with it's own take.  There are two places I know that are
the  most anechoic in the haouse: the closet (but, too often, the walls
transmitt building noise), and under the bed (recalled from when I was
still small enough to fit under there-lots of dead air space). Here's
the mic set up I centered underneath the bed:

I then recorded a digital metronome set at 40bps, about 3 feet away. The
consistent tone beat allows me to aurally"guage" level recordings (ear
experience) and the beat interval is long enough for the recording
set-up to recover and record the relative self-noise.  (All done, of
course at 2:30am, well 3:00am since the 'fridge kicked in with a
perceptable humm ;)  The resulting self-noise recordings give me a a
starting point for sampled  removal that must be present in all
recordings where that noise is too distracting.  That's the theory,
anyway.
