FIELD: physics.
SUBSTANCE: apparatus for suppressing noise in the passenger cabin of a vehicle has at least one converter, a programmable computer and at least one acoustic sensor. The computer is configured to apply the electroacoustic model of the passenger cabin to the model of an adjustment system, having a fixed coefficient master controller which is connected to a variable coefficient unit, having a Yule parameter in form of a Yule Q unit. In the method, the first step involves determining and calculating the electroacoustic model and control law for at least one predetermined noise frequency. At the second step, the computer applies the control law to the electroacoustic model in real time in accordance with the current noise frequency to be suppressed.
EFFECT: improved method.
