Definition of Adaptive noise cancelling
Adaptive noise cancelling is a signal processing technique for suppressing interference corrupting a received signal where the interference is known and is accessible but unavoidable and where the target signal and the interference are unrelated. Examples of such situations include:
a microphone attempting to receive speech near machinery or other noise sources in the environment, such as an aircraft cockpit
a naval ship towing a sonar array where the ship's own noise masks a much weaker detected target signal
