Abstract (en)

[origin: WO2010136661A1] The invention relates to a method and a device for suppressing noise in the passenger compartment of a vehicle, which includes at least one transducer, a programmable computer, at least one acoustic sensor, the computer being configured such as to apply an electro-acoustic model of the passenger compartment to a correcting system model comprising a central corrector with fixed coefficients joined to a block of variable coefficients, comprising a Youla parameter in the form of a Youla block Q. The first phase comprises determining and calculating the electro-acoustic model and the correction control law for at least one predetermined noise frequency. In a second phase, in real time, the computer applies the correction control law to the electro-acoustic model in accordance with the common frequency of the noise to be suppressed.
