I am also a beginner at this sport.  I have had a SG sensor running since
June.  I guess I'm a slow learner, but I just can't belive how sensitive the
darn thing is.  I have had the sensor covered from the beginning, and the
interior of the enclosure is stuffed tight with laminated cardboard to
eliminate the last shred of free air space.  What I didn't do until recently
was to seal the bottom of the enclosure to prevent air currents getting
under the edge of the cover.  The other day I finally got around to packing
a couple of rags around the bottom of the cover.  The result was the
complete elimination of the major component of my background noise, which
showed up as a signal with an average period of around 25 seconds.  It cut
my overall noise level by more than half.

My other problem, which probably doesn't have a solution that doesn't
involve pouring concrete into a hole in the back yard, is that there isn't
any place in my basement that is sufficiently isolated from foot traffic on
the floor above.  The best compromise is a spot under the bedroom, but I
have a very accurate record of when we go to bed and get up in the morning
every day.
