Active Noise Cancellation (ANC) system and method comprising an ANC signal which is generated by a signal processor in response to an ambient noise signal, comprising detecting the wind amplitude, controlling the cut-off frequency of a high pass filter (HPF) of the signal processor based on ...
Active Noise Cancellation (ANC) is a technique used to reduce unwanted noise in an audio signal. One popular approach to achieve ANC is by using a Finite Impulse Response (FIR) adaptive filter. In this study, we investigate three different algorithms for implementing an ANC system: Least Mean...
