RNC controller uses reference signals received from accelerometers placed throughout the suspension and chassis.
Microphones in the car roof further enhances system performance.
Lightweight materials enable OEMs to lower fuel consumption and CO2 emissions
EOC controller uses the engine RPM signal as a reference to generate a sound wave that is opposite in phase to the engine vibration-induced noise.
Error microphones provide feedback on the amplitude and phase to refine noise-cancelling effects.
Predicts noise levels more accurately at occupant ear locations using existing error microphones.
Improves depth and frequency range of cancellation.
Predictions enable cost savings through reduction of hardware.
