ACTIVE NOISE CANCELLATION METHOD, DEVICE, AND SYSTEM - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18338851 Titled 'ACTIVE NOISE CANCELLATION METHOD, DEVICE, AND SYSTEM'
Simplified Explanation
The abstract describes a method for active noise cancellation. It involves capturing the surrounding sound to create an ambient audio signal. The method then determines a working status and identifies any desired signals based on that status. These desired signals, which contain content of interest, are then removed from the ambient audio signal to create a reference signal. Finally, a to-be-played signal is determined based on the reference signal.
Original Abstract Submitted
The present discloser relates to a method for active noise cancellation. An example method includes: capturing an ambient sound to determine an ambient audio signal; and determining a working status, determining at least one corresponding wanted signal based on the working status, and then removing the at least one wanted signal from the ambient audio signal, to obtain a reference signal, where the wanted signal includes content of interest. The example method further includes determining a to-be-played signal based on the reference signal.
