Noise reduction systems and methods

摘要

A noise reduction system for use with noise generating equipment. The system includes at least one sensor to generate one or more input signals, with each input signal being representative of an operating condition of the equipment. The system also includes a signal processing unit in communication each sensor to receive the input signal(s) and to generate at least one anti-noise output signal based on the input signal(s). The system further includes at least one output device in communication with the signal processing unit to generate anti-noise based on an anti-noise output signal. The anti-noise reduces noise emitted by the equipment during operation.
