1. A method of training a road noise cancelation (RNC) system for a vehicle, the method comprising:
providing inputs to RNC system, the inputs obtained from: a set of ear-mounted microphones on a user of the vehicle, at least one transducer, an accelerometer, a set of cabin microphones in the vehicle, and a controller area network (CAN) bus,
wherein the inputs from the set of ear-mounted microphones on the user approximate a signal detected by the ears of the user;
adapting a set of parameters in the RNC system defining an estimated signal detected at respective ears of the user based on the inputs; and
generating at least one of the following for input during an operating mode of the RNC system:
estimated ear microphone signals based on the adapted set of parameters, or
a set of projection filters for use in determining an estimated ear signal at the respective ears of the user.
