Systems and methods for noise reduction using sub-band noise reduction technique

A system for noise reduction, comprising:

• a sub-band noise sensor including a plurality of acoustic-electric transducers and a plurality of sample modules, each of the acoustic-electric transducers having a unique frequency response and being configured to detect a noise and generate a sub-band noise electrical signal by processing the noise, each of the sampling modules being configured to receive one of the sub-band noise electrical signals and sample the received sub-band electrical signal to generate a sub-band noise signal, wherein sampling frequencies of at least two of the sampling modules are different:
• a plurality of sub-band noise reduction modules, each of the sub-band noise reduction modules being configured to receive one of the sub-band noise signals from the sub-band noise sensor and generate a sub-band noise correction signal for reducing the received sub-band noise signal;
• and
• an output module configured to receive the sub-band noise correction signals and output a noise correction signal for reducing the noise based on the sub-band noise correction signals.
