[1] I did the analysis of this effect some years ago for loudspeaker
cables and derived expressions for how the capacitance and inductance of
zip-cord speaker cable varied with current flow. The coefficients (of
dependence on the square of the current) in typical cases were in the
1-10 parts per billion range, IIRC. I decided they were too small to
matter.

WRT The ClarityCap papers I've not yet seen any figures for the SPL
generated for a given input voltage. So no idea how loud the results may
be. The paper also mentions doubling - which is what you'd expect if the
mechanical movements are due to the force between the plates caused by the
charges on them.

Slainte,
