Hyundai has unveiled its Road Noise Active Noise Control (RANC) system, an advanced active noise cancellation technology that reduces cabin noise by 3dB (50% sound energy) in electric vehicles. Slated for debut in a 2025 Genesis EV, RANC processes road noise 4.5x faster than conventional systems, delivering near-silent cabin comfort. This innovation addresses a key EV pain point—where the lack of engine noise makes tire and wind noise more noticeable.
How Hyundai’s RANC Works
The Science Behind Active Noise Cancellation
Unlike traditional noise insulation, active noise cancellation (ANC) uses microphones and speakers to detect and counteract unwanted sounds in real time. Hyundai’s RANC system takes this further by:
- Processing noise in 0.002 seconds (faster than the 0.009s it takes for sound to reach passengers).
- Using accelerometers to predict road vibrations before they become audible.
- Generating inverse sound waves via the car’s audio system to neutralize noise.
Why This Matters for EVs
The Growing Demand for Quieter EVs
A 2024 McKinsey study found that 72% of EV buyers prioritize cabin quietness, ranking it above infotainment and even range in some luxury segments. Historically, brands like Lexus and Mercedes-Benz led in noise insulation, but Hyundai’s RANC could democratize premium acoustic comfort.
EVs Expose New Noise Challenges
Since EVs lack engine noise, previously minor sounds—like tire hum and wind buffeting—become more pronounced. Hyundai’s tests show RANC reduces perceived noise by up to 30%, a critical advantage in the luxury EV market.
When Will RANC Hit the Market?Z
- First application: 2025 Genesis electric sedan (likely the Genesis Electrified G80).
- Expansion plans: Hyundai confirms RANC will trickle down to Kia and mainstream Hyundai EVs by 2026.
- Competitive landscape: BMW’s Active Sound Control+ and Tesla’s patented noise-canceling tech are in development but not yet production-ready.
Conclusion: A Game-Changer for EV Comfort
Hyundai’s RANC system sets a new standard for in-cabin quietness, addressing a major EV drawback. As automakers compete on refinement, active noise cancellation could become as crucial as battery tech in luxury electric vehicles.
