Abstract: A fan active noise self-lowering system includes a fan, a push assembly, at least one pickup unit and a digital signal processing unit. The pickup unit serves to capture the noise made by the fan to generate a noise input signal and transmit the noise input signal to the digital signal processing unit. The digital signal processing unit receives the noise input signal and processes the noise input signal to output a control signal for controlling the push winding assembly to operate so as to push the fan impeller of the fan to move up and down. Accordingly, the fan impeller will generate a reverse sonic wave to offset the noise.

Abstract: Methods and systems for reducing noise relating to an electronic system are disclosed. The methods and systems determine a noise signature, which characterizes a targeted noise of the electronic system. A cancellation signal is then generated based on this noise signature, so that if the cancellation signal is transmitted, the targeted noise is at least partially reduced.

Abstract: A method of optimizing placement of a control source relative to a noise source includes establishing a first pool of constructive chromosomes, each constructive chromosome defining a potential spatial position for the control source in an acoustic space and each constructive chromosome including a plurality of constructive genes having a value-based value that represents an ordinate related to the potential spatial position. A second pool of constructive chromosomes is established by manipulating the value-based values of constructive genes from at least a portion of the plurality of constructive chromosomes of the first pool to create a plurality of modified constructive chromosomes, and evaluating a fitness characteristic of at least some of the constructive chromosomes from the first pool and/or at least some of the constructive chromosomes from the second pool. A portion of the constructive chromosomes are eliminated from the first and/or second pools based on the fitness characteristic.

Abstract: An electronic system includes a fan module, a reference microphone, a micro speaker module, and an active noise cancellation controller. The micro speaker module provides a noise-cancellation signal according to a micro speaker control signal for canceling the noises generated during the operation of the electronic system. The reference microphone outputs a wide-band noise signal associated with the operation of the fan module. The active noise cancellation controller outputs a virtual error signal according to a first transfer function between the reference microphone and a physical microphone when the fan module operates with a predetermined fan speed, a second transfer function between the micro speaker module and the physical microphone when the fan module is not in operation, and the wide-band noise signal. The active noise cancellation controller provides the micro speaker control signal according to a synchronization signal, the wide-band noise signal and the virtual error signal.
