This is an implementation of the calculation of STC value according to ASTM E 413-04. Classification for Rating Sound Insulation.
Input the transmission loss in one third octave bands (dB) and enter the frequency bands and the program will calculate the STC value and produce a graph.
The center frequencies do not have to be exact as the program matches them to the reference contour and applies a tolerance.
