Noise suppression using a microphone array and neural networks (NN) has been investigated .In this study, the output from a microphone array is converted into a spatio-temporal sound pressure distribution image, and its two-dimensional (2D) amplitude and phase spectrum obtained by the 2D fast Fourier transform is used for noise suppression. In addition, a system that can handle multiple noise sources is proposed and its performance is evaluated. In order to reflect the dependence of the phase characteristics on the amplitude characteristics, a DNN that simultaneously estimates the amplitude and phase of the noise spectrum was used to improve the suppression performance. Results of computer simulations showed noise suppression of about $-23 sim -20$~dB for two noise sources. |
