Active noise cancellation systems and methods include a feedforward path configured to receive a reference signal comprising ambient noise and adaptively generate an anti-noise signal to cancel the ambient noise and comprising an adaptive gain component configured to adaptively adjust a gain of the ...
A major difference between the two ANC topologies is the noise reduction characteristics. Feedback systems usually have better low frequency performance (<100Hz) but do not reach the bandwidth of feed-forward systems. Typically feed-back systems can work up to 1kHz and have a more flat ANC dis...
and the phase of the cancellation waveform leaving the headphonedriversneeds to perfectly line up with the phase of the noise when it reaches your ear. These systems need to be finely tuned, but even then, you won’t ever see

One major problem in telecommunication systems is the presence of background noise (ambient noise) that can interfere with the user's hearing (i.e., the user's ability to understand what is being communicated). Often times, a user may use a mobile phone in a noisy environment such as a...
