|True Sound Hole
Some nice pictures and diagrams of the TSH, flue, and SAC exit can be found at http://goss.rho.net/flute/htm/fipple.htm
Note: Flue design is tied to TSH design. See topic "Flue" for more information about flue design.
Generally, the flue width should be the same as the TSH width.
From Dale at Native Flute Woodworking Yahoo group:
|Usually , the width of the TSH is something like half the bore
diameter (for example ,a 7/16 width TSH for a 7/8 bore..) , and the
length 7/32 (or less...More , the sound becomes breathy).
But these measurments are just standard values , that i have seen in
some manuals and plans , and these dimensions can vary a lot with
different makers (and different kinds of flute design...).
The more the TSH is long , the more the sound becomes breathy.
The more the TSH is short , the more the sound becomes buzzy , and
The more the TSH is wide , the more the fundamental becomes sharp.
Relation to bore size and key
Round vs Rectangular
