AGC’s Glass Noise Cancellation (GNC) Module is an aircraft cabin window module that actively reduces noise transmitted through glass. A microphone or sensor detects exterior noise, and an actuator integrated with the glass generates opposite-phase vibrations to reduce sound entering the cabin. In demo measurements using a mock-up, the module achieved noise reduction of up to approximately 10 dB. Unlike headphone-based noise cancellation, GNC reduces noise at its transmission path without requiring passengers to wear personal devices. By combining AGC’s glass engineering and vibration-control expertise, GNC turns glass into an active acoustic component while maintaining visibility and appearance. Beyond aircraft, AGC envisions extending this technology to other mobility applications, including trains and automobiles, as well as architectural settings such as hotels, helping create quieter, more comfortable spaces across a wide range of environments.
