Abstract
Some experiment results of multilayer perceptron neural networks for active noise cancellation (ANC) are presented in this paper. Active noise cancellation is an approach to noise reduction in which a secondary noise source destructively interferes with the unwanted noise. Conventional ANC systems apply a digital filter to cancel the noise and suffer from the fact that each noisy environment needs to be treated individually. In this paper, we introduce a three-layer MLP neural network to replace the aforementioned filter. We apply this architecture to three different broad-band-noise environments and achieve 20 dB noise attenuation.
