Active Structural Acoustic Control (ASAC) is an effective measure to reduce the windshield-vibration-induced interior noise in an automobile passenger compartment. Different control strategies for the active reduction of windshield-vibration-induced car interior noise are developed, experimentally validated, and now available. The comparison of the vibration levels in open and closed loop show a global reduction of 5dB to 7dB in the acoustically relevant frequency band containing the second and third eigenmode of the windshield system (100 Hz to 150 Hz). The acoustic effects are reflected in a reduction of up to 15dB in SPL at 145Hz.
