Abstract:
A remote microphone system for a vehicle may include at least one physical microphone arranged within a vehicle cabin configured to generate an error signal at a virtual microphone location within the vehicle, a database configured to maintain a look up table of premeasured seat positions and associated transfer functions, and a processor. The processor may be configured to receive a seat position indicative of a seat location within the vehicle, and apply a transfer function associated with the premeasured position to a primary noise signal of the at least one physical microphone to generate the error signal.
