The cooker hood comprises a hood body, a chimney, a fan motor, a sound-absorbing member, and an ANC system, in which the sound-absorbing member blocks or destroys a sound wave of a noise sound produced in case of the operation of the fan motor. The ANC system comprises reference microphones, error microphones, an electronic device, and loudspeakers, and is utilized for collecting a noise sound in chimney, generating an anti-noise signal according to the noise sound, and driving the loudspeaker to broadcast an anti-noise sound toward an internal of the chimney.
