This site being somehow "Harman positive" , I don't know if this was mentioned, looks interesting:

Full press release (February 03, 2020)

excerpt:
Hyundai Motor Company and HARMAN International launch the world’s first road noise cancellation system into production
Co-developed with HARMAN, based on its HALOsonic suite of noise cancellation technologies, Hyundai Motor Company’s (HMC) new Road-Noise Active Noise Control (RANC) system combats road noise to increase driving pleasure by reducing unwanted noise by up to 50 percent. Genesis GV80 SUV is the first vehicle to feature innovative noise cancellation technology

How it works
The RANC control processor uses reference signals received from acceleration sensors placed strategically along the suspension and chassis to predict noise transferred into the cabin and to generate an anti-noise wave in real-time. Compute time and signal transfer speed are optimized to allow for an analysis of the intruding noise and the generation of the anti-noise within milliseconds, thereby preventing the noise from reaching the occupants’ ears. Error microphones constantly monitor the system performance in each seat location to ensure a more pleasant ride for all vehicle occupants.

You can try Road Noise Cancellation, it absorbs noise and can also prevent them from passing from road to residential areas. Specifically, the most commonly used acoustic solutions, as well as the cheapest residential soundproof barrier products, are noise barriers. These blocking road noise products are sold by standard size blankets or rolls, making the transformation of existing structures easy and cost effective.

You just googled Road Noise, found this place and made an account here to link to your company. The original post is about road noise inside of the car itself.
