Provided in the present application are an open wearable acoustic device and an active noise cancellation method. The acoustic device comprises a first sound sensor module, a loudspeaker and a noise cancellation circuit. A first sound signal collected by the first sound sensor module comprises an ambient noise signal from ambient noise and a leakage signal from the loudspeaker. The noise cancellation circuit may generate a quasi-ambient noise signal by means of first eliminating the component of the leakage signal in the first sound signal, and may then generate a first noise-eliminated signal on the basis of the quasi-ambient noise signal.
