My theory was that if stuff transmits through the bones ok, then 
they're like the wires;
a break in the wire [i.e. a gap between two bones] is therefore like a 
capacitor!
More sensibly, if the bone is vibrating into some material with a fixed 
compressibility,
then it's almost 'charging' the material like a capacitor....
