Hyundai is working on developing the world's first Road Noise Active Noise Control system (RANC)
RANC [...] is able to analyze various types of noise in real-time and produce inverted soundwaves – for example, it can counteract the sounds created between tires and wheels or the rumble sounds coming from the road.
According to Hyundai, RANC can reduce in-cabin noise by 3 db.
This technology was developed with future vehicles in mind. As internal combustion models get phased out, vehicle noise will primarily come from three sources: powertrain, road and wind – but since electric and fuel cell vehicles make almost no powertrain noise, quieting road and wind noise will become imperative.

So much for "the world's first". More like "the old patents ran out".
I've heard from someone having a ride in the demonstrator car. First they mixed massive V8 or thoroughbred V12 sound into the antinoise, which must have been mentally disturbing, given that it was installed into a tiny Citroen AX. Then they switched off the mix-in, which resulted in a stunning impression of silence.
