Embodiment Construction
[0045] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.
[0046] There is a nonlinear link in the propagation path from the A-position noise source to the B-position speaker. For example, if the original noise is too large, the reference microphone is nonlinear. If the feedforward filter can use a nonlinear filter, it can better deal with the noise. control, and the neural network is a nonlinear controller, based on this, the neural network can be used to realize the feed-forward filter to...
