Abstract

A method for reducing noise in at least one monitor position in a vehicle compartment by actively controlling the power of a primary noise (dm(t)) as sensed at two or more control positions in the vehicle compartment, the method comprising the updating of filter coefficient(s) of (an) adaptive filter(s) (w(n)) based on variable contribution of error sensors and actuator(s) for different noise source operating conditions.
