The best performance rating on the operable test is a zero drop in the assembly s stc rating.
Stc is determined by a weighted average of tl values taken over 16 frequencies which are fitted to a curve in a method defined by the astm e413 classification standard for rating sound insulation.
Operable stc ratings are always equal to or lower than the sealed in place ratings.
For example a door with a stc 45 rating can only achieve an operable stc of 45 at its very best.
