Ear Microphone Signal Estimator and/or Projection Filter Generator for Road Noise Cancelation (RNC) System

A system comprising:

• a vehicle audio system including at least one transducer for providing an audio output to a user in a vehicle;
• a vehicle sensor system for obtaining sensor inputs about the vehicle;
• and
• a road noise cancelation (RNC) system connected with the vehicle audio system and the vehicle sensor system, the RNC system including a machine learning (ML) module and a linear adaptive (LA) module,
• wherein the ML module is configured to:
• receive inputs from:
• the vehicle audio system and the vehicle sensor system;
• apply a set of parameters defining an estimated signal detected at respective ears of the user based on the inputs, wherein the set of parameters are applied based on at least one of:
• estimated ear microphone signals, or
• a set of projection filters for use in determining an estimated ear signal at the respective ears of the user, and
• wherein the LA module is configured to:
• generate noise cancelation signals for output by the at least one transducer based on the applied set of parameters.
