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.

    My amp has a digital volume scale from 00-99, and is - as far as I can tell - logarithmic, and thus approximately linear in dBAs. It has a usable range of about 70 between being below the noise floor (radiators, fans, streets and weather outside) and annoyingly (but not painfully) loud. So that's about 1.5dB/step. The remote has dodgy volume buttons, and it's random whether a press will get registered. However, I can tell, across the whole sensible range (20-70), whether the volume has changed or not with every button press. OK, I know I have better than average hearing (I can still hear CRT flyback at >17KHz from across the room and I'm decades older than I was when I first noticed that I could hear some networks cards' payloads, and even RAM stress tests), but to be honest anyone who can barely hear *3* such 1.5dB steps has to be as deaf as a post, IMNSHO.
