Active noise-control device

An active noise control device comprising two passive attenuation earpieces, each having an external microphone, an internal microphone, and a loudspeaker for playing back a noise into the earpiece;

• the control device having a first processing channel comprising a feedforward filter connected to the external microphones, a feedback filter connected to the internal microphones, and a playback module supplying each loudspeaker with a playback signal derived from the output signals of the feedforward filter and of the feedback filter;
• the control device including a second processing channel comprising a sound source identification module for identifying sound sources, the second processing channel being implemented in parallel with the first processing channel and being adapted to adjust the settings of the first processing channel;
• wherein the first processing channel includes a partition module for partitioning an external acoustic space, which module is situated upstream from the feedforward filter and makes use of a directional microphone formed by the external microphones in order to partition the external acoustic space into a plurality of incidence sectors;
• wherein the identification module is adapted to identify whether an external noise in each incidence sector is a useful noise or an undesirable noise.
