I read here again and again that vehicles with VSG discs have a much better sound insulation than vehicles with normal ESG side windows. With overall the same material thickness, the better sound insulation by an intermediate !thin! (so-called) acoustic foil should be considered physically, but at most in a small single-digit percentage range. Or even with these small dimensions the M Asse-Feder-Mass-System? Does anyone have any more detailed information about this?
