Estimating the term…
An active noise cancellation system in a passenger compartment (of a vehicle is provided with: reference sensors designed to detect noise reference signals indicative of ambient noise to be cancelled; error sensors, arranged within the passenger compartment, so as to detect error signals at noise cancellation zones for the purpose of a feedback control of the noise cancellation; speakers designed to reproduce sounds within the passenger compartment; and a digital processing unit, designed to control the speakers to generate anti-noise signals to be reproduced in the passenger compartment, for the purpose of noise cancellation, by implementation of a noise cancellation algorithm based on the reference signals and the error signals and on the determination of acoustic paths in the passenger compartment. In particular, the system has a distributed intelligence, wherein the reference sensors and/or the error sensors are internally provided, in an embedded manner, with digital processing capabilities and are configured to contribute, in cooperation with the digital processing unit, to the implementation of the noise cancellation algorithm.
An active noise cancellation system (10) in a passenger compartment (4) of a vehicle (1), comprising:
An active noise cancellation method in a passenger compartment (4) of a vehicle (1), comprising:
(14) speakers (12) to generate anti-noise signals to be reproduced in the passenger compartment (4), for the purpose of noise cancellation, by implementing a noise cancellation algorithm based on said noise reference signals and said error signals and on the determination of acoustic paths in the passenger compartment (4),
(16) for the purpose of the noise cancellation operations.
