Greetings, 
    Sometimes the hinges themselves rattle,  I hit them with a punch to 
tighten, or I have also dropped in three or four drops of CA to fill up micro 
gaps.  Seems to keep things quiet for several months, at least. 
Sometimes the small board itself is resonating with some of the notes, 
(especially after a fresh voicing), and in those cases, bending one or two of 
the hinges themselves will stiffen things up with some flex.  When that 
hasn't worked, (humidity, moon phase, karma, who knows?),  I have pulled a 
black rubber wedge down between the flap and the fallboard, cut it so it 
wasn't really visible, and put a small piece of black gaffer's tape over the 
end.  This usually works until somebody takes it all off and wonders what was 
it doing there.  
Regards,
