it certainly makes sense, the smoother the surface the less air disruption and therefore the less noise (assuming no harmonic ringing from the shock of launching)
so more noise from fletching than heads.
if anything I would have thought that the freezer tape would be noisier based upon the coefficient of friction...
I do wonder though, if you made fletchings with the trailing edge like the trailing edge of an owl's wing: would you get a quieter fletch?
well you might need to play with the leading edge too:
