Hyundai researchers developed next-generation active noise cancellation (ANC) technology by applying more sensors and computing power to dampen in-vehicle sounds. The Road Noise Active Noise Control (RANC) system upgrades the current ANC, which muffles noise that is constant or predictable.
RANC can analyze a range of noise types in real time and cancel them out by generating inverted soundwaves to neutralize buzzing infrasound or rumbling from the road.
Hyundai claims RANC can accurately detect, analyze, and cancel out noises affecting the driver, front passenger, and rear-seat occupants separately, reducing in-cabin noise by 3 decibels.
