Dual-Impedance Foil Technology (DIF)

Dual-impedance foil technology is used on high-volume vehicles to reduce noise between engine and passenger compartments.  It reduces cost and weight while maintaining NVH performance.  Versus competitive systems, a perforated PE/PA foil replaces one of two layers of noise-absorbing fabric (typically PET and cotton fibers).
