And different instruments support them differently.  But they are not in the overtone series of the sounding length of the instrument, so they are being created by the player and - I believe - a higher harmonic of the actual sounding length reinforces the the tone at the octave and above, giving the notes some resonance and a touch of "focus".  For instance low "B" above pedal Bb, played in 7th position, resonates 7th position B above.

    What strikes me as being odd about them, is that some are easier 
than others.  Seems to me they ought to all be about the same, since 
they are all -- well, false, or artificial -- but some of them are 
rather difficult to sound, like a low E flat in flat third, but no 
F-attachment -- but a low C on a 2B -- well, you can just about blow the 
bell off the darn horn!
