Noise cancelling in audio signal with adaptive filter - WSEAS

As it can be observed, the adaptive filter noise canceller is a system with feedback as a system with automatic control. For this reason, there is stability problem. The problem arises when the error signal’s amplitude increases in accordance with time or when no convergence is obtained.

Fig 1: Adaptive Noise Cancellation i.e., this signal and the primary signal are superimposed, so that the noise signal is cancelled. In Fig. 1 the reference input is processed by an adaptive filter, which is accomplished through an algorithm.

The Single channel adaptive feedback Active Noise Cancellation (ANC) system works by processing the acoustical noise (the “target” noise) that would like to reduce, by producing an anti-noise which cancels out the noise component by the method of adaptive filtering. Therefore, the main aim of ANC system is to reduce the noise component from the signal of interest.
Adaptive Noise Cancelling for audio signals using Least ...

The reference input is adaptively filtered to obtain a close estimate of primary input noise which is then subtracted from the corrupted signal at the primary input to produce an estimate of a clean uncorrupted signal, which is the Adaptive Noise Cancellation output. A desired signal corrupted by noise can be recovered by feeding back this output to Adaptive …

square (LMS) adaptive filter of audio signals. It restores the desired audio signal by passing the noisy speech through a FIR filter whose coefficients are estimated by minimizing the mean square error (MSE) between the clean signals [10]. In many applications, LMS adaptive filtering algorithms are widely used, partly be-
Adaptive Noise Cancellation
https://www.cs.cmu.edu/~aarti/pubs/ANC.pdf
In noise canceling systems a practical objective is to produce a system output sˆ= s + n – nˆthat is a best fit in the least squares sense to the signal s. This objective is accomplished by feeding the system output back to the adaptive filter and adjusting the filter through an LMS adaptive algorithm to minimize total system output power.
Active Noise Cancellation in Audio Signal Processing
https://www.irjet.net/archives/V3/i11/IRJET-V3I1104.pdf
effective scheme to accomplish noise cancellation is to use adaptive filter. Active Noise Cancellation (ANC) is achieved by introducing “antinoise” wave through an appropriate array of secondary sources. These secondary soures are interconnected through an electonic system using a specific signal processing

When it comes to the “adaptive noise cancellation” mentioned in the article, this seems to be very similar to the active noise cancellation (ANC) used by other earbuds. Apparently the OnePlus Buds Pro will use three microphones to monitor external sounds and “intelligently produce noise-canceling counter frequencies” to create an audio bubble.
