  For horn length x = at throat to at mouth
       Take a length of y mm diameter braided cable sleeving      Fill with stone aggregate of particle diameter > max sleeving wall gap      Wrap around horn at x
  end
  By varying y one can adjust damping at different points along the length of the horn, if that turns out to be beneficial. Another advantage is that because the sand is not bonded one might get better damping than with most other materials. 
  Any criticisms?
