Abstract (en)
It is proposed active noise control method for reducing the amount of noise in a local zone (CZ) comprising capturing at least one audio signal (e, x) inside an area (A) including at least the local zone and generating an anti-noise signal (y) which is function of this at least one audio signal and from a model of the acoustic characteristics of at least a part of the area, wherein this model is selected among a set (B) of predetermined models in accordance with at least one physical measurement (s(n)) representative of these acoustic characteristics.
