Abstract[English]
Presented herein are techniques for reducing distortions in noise cancellation systems, including but not limited to body noise cancellation filtering systems. In one aspect, a method is provided. The method comprises: receiving at least one input signal at a noise cancellation system; and processing the at least one input signal using the noise cancellation system to generate a noise cancellation output signal, wherein the noise cancellation system is controlled by a variable filtering strength parameter that is a function of a level of the at least one input signal.[French]
Sont présentées dans la description des techniques de réduction de distorsions dans des systèmes d'annulation de bruit, comprenant sans caractère limitatif des systèmes de filtrage d'annulation de bruit corporel. Selon un aspect, un procédé est proposé. Le procédé consiste à : recevoir au moins un signal d'entrée au niveau d'un système d'annulation de bruit ; et traiter le ou les signaux d'entrée à l'aide du système d'annulation de bruit pour générer un signal de sortie d'annulation de bruit, le système d'annulation de bruit étant commandé par un paramètre d'intensité de filtrage variable qui équivaut à fonction d'un niveau du ou des signaux d'entrée.
