NOISE CANCELLATION MODULE

摘要

A computer system (100) having a noise cancellation module (102) and a method of canceling noise using a noise cancellation module (102) in a computer system (100) are described. The computer system (100) includes a processor (108) for controlling operation of the computer system (100), a noise cancellation module (102) coupled to the processor (108), and a memory (112) coupled to the processor (108) and storing operating instructions and at least one sequence of noise cancellation instructions. The noise cancellation instructions cause the processor (108) to generate cancellation audio signals responsive to receipt of audio signals from the noise cancellation module (102), and transmit the generated cancellation audio signals to the noise cancellation module (102). The method includes sensing, by the noise cancellation module (102), an audio signal generated by the noise-generating source and causing the processor (108) to generate a noise cancellation signal responsive thereto. The noise cancellation module (102) generates an audio signal based on the generated noise cancellation signal from the processor (108).
