A non-dimensional parameter is developed and data provided to estimate the required mass penalty to achieve satisfactory interior cabin noise levels for advanced propfan powered aircraft. The cabin noise criterion is 80 dBA which is representative of present-day turbofan-powered aircraft interiors and was used by NASA in a related study. Numerical results are given here for an advanced narrow-body powered by two 10-bladed propfans, cruising at 0.70 and 0.80 Mach number, designated as the ATX-100.
