Abstract
Systems and methods to cancel noise in a vehicle are disclosed. A first speaker is positioned forward of a steering wheel of a vehicle. The first speaker generates a first signal configured to acoustically cancel noise produced by operation of the vehicle. A second speaker is positioned forward of the steering wheel. The second speaker generates a second signal to acoustically cancel the noise produced by the operation of the vehicle. The first and the second speakers are capable of generating the first and the second signals independently of one another.
