Road Noise Cancelation (RNC) with User Position Tracking

Abstract

Various implementations include road noise cancelation (RNC) systems and related approaches for RNC. Certain implementations include a RNC system having: a position sensor configured to detect a position of an occupant in a vehicle; a transducer configured to receive a cancelation signal and produce a cancelation audio signal in the vehicle; a microphone configured to provide an error signal representative of acoustic energy at a first location in the vehicle; a set of projection filters configured to filter the error signal to provide an estimated error signal at the position of the occupant in the vehicle, wherein the set of projection filters are selected from a predefined library of projection filters associated with a set of occupant positions in the vehicle; and an adaptive module that adjusts the cancelation signal based on the estimated error signal.

Dependencies are inferred from the claim text.
