Claims8
An active noise cancelling device for a mobile vehicle, comprising:
- a noise extractor configured to generate cancellation target noise information from an input sound signal;
- and
- a controller configured to provide a noise control signal to an audio transmission device based on the cancellation target noise information,
- wherein the noise extractor is further configured to vary a period for generating the cancellation target noise information based on driving information of the mobile vehicle,
- wherein the driving information of the mobile vehicle includes at least one of acceleration information, torque output information, revolutions per minute (RPM) output information, or pedal and brake input/output information of the mobile vehicle, and
- wherein, when the driving information of the mobile vehicle is received, the noise extractor predicts a level of noise generation according to a driving situation by comparing the received driving information with pre-stored data, and varies the period for generating the cancellation target noise information according to the predicted level of noise generation.
