WebSound transmission class (STC) ratings solve that problem by giving a single value to acoustical performance for a door. 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. Webarrive at a single figure rating for comparing the effectiveness of walls in resisting the transmission of airborne sound. This is defined as the sound transmission class (STC). It is determined by fit-ting the proper STC contour (ASTM E 413) to the plot of sound transmission loss vs frequency (ASTM E 90). The STC is then equal to the trans-
