Broadbanding of a NN-based microphone-array system by decomposing into frequency components
IEEE Global Conference on Consumer Electronics, pp. 1-2, 2017.
Our previous microphone-array system with a neural network (NN) structure has yielded a sharp directivity by training the NN using temporal-spatial patterns in sound pressure for sinusoidal signals at multiple frequencies. Although this system achieved a sharp directivity for trained and untrained frequencies, the directivity is effective...More
