CP 606 ,shows in you data sheet 68db, however can you send the documentation for the same.
CP 606 in your technical data sheet it shows Sound transmission classification (ASTM E 90-99) 68.
However in your stc it shows maximum of 56db,
Do you have another data sheet for this as both values are different
