Abstract:
Methods and apparatus are provided for controlling noise in a cabin of a vehicle. In various embodiments, a method for controlling noise in a cabin of a vehicle includes measuring a first sound via a microphone in the cabin; obtaining a second sound from a loudspeaker of the cabin; estimating, via a processor, a third sound at a virtual location that is remote from both the microphone and the loudspeaker, using the first sound, the second sound, and one or more transfer functions; and applying active noise cancellation for the cabin based on the third sound at the virtual location.
