This has to do with the drivetrain of the car. In simpler terms, the power delivery system of the car. A 2wd or a two wheel drive is any general stick shift(manual transmission) car you drive. Either the front two rotates and pull your car or the back two rotates and push your car forward. For a 4wd or a four wheel drive, you can switch to all of the wheels being driven. Provides better grip on the road.
How the system works. Active Noise Cancellation (ANC) is designed to dramatically reduce low frequency noise in the interior. The system operates whenever the car is running, regardless of whether the audio system is on or off. There are two microphones in the cabin area.
Noise canceling headphones work by recording sound and playing a phase inverted sound to cancel it. With a laptop the mic is first off shitty, and nicely in front of you this means sound coming from behind you will reach your ears first before it even hits the mic.f you mean noise reduction, this question could be relevant: superuser.com/questions/274604/â¦ One answer mentions some software, of which SoilCall Pro does work (at least to reduce most of the noise I had), but has some sound quality issues.
