The sound wave that source of sound offsets；
Data management system is electrically connected 3D depth transducer group, microphone group and player group, according to 3D depth
Sensor group and the data of microphone group acquisition calculate and obtain human ear and microphone and the distance between human ear and player,
Player is controlled again and issues the sound wave of but direction identical as noise frequency and intensity and opposite in phase in real time to offset noise, is realized
Noise cancellation.
The 3D depth transducer group includes at least one 3D depth transducer.
The microphone group contains at least two microphone.
The player group contains at least two player, i.e., a broadcasting is at least arranged at the left and right ear of people
Device.
The noise source data packet of microphone acquisition contains：Intensity, frequency, direction and the phase of noise source.
The position of microphone in the microphone group and the position of the player in player group are fixed, positions
Information is stored in data management system.
The data management system is using the hardware device for being able to carry out data storage and analysis.
The utility model is based on three-dimensional imaging depth measurement and active noise control technique, can eliminate around human ear in real time
Noise, make one in specific environment（Such as：Airplane, steamer, automobile etc., but it is not limited to these）In do not done by any noise
It disturbs, whenever and wherever possible in a kind of more quiet environment.
