Unfortunately you can't convert between the two with a calculation.
STC is a single number that is derived using 1/3 Octave Band dB measurements from 125 Hz to 4 kHz. You can research the ASTM E 413 standard if you're interested in seeing what's involved.
There is no way to go from an STC rating back to decibels.

Sí, lo conseguí!
Busqué información sobre STC, es un valor de resistencia sonora que puedes calcular segun la sección constructiva de cada división. Parecido al cálculo de transmitancia térmica.
