ABSTRACT:
Noise data from a noise source is provided for a neural network. An output signal from the neural network is provided for a node of a hidden layer H of the neural network. The weight of the neural network is updated by an update unit according to an error signal e.sub.j0 detected by a microphone, thereby outputting a deadening sound from a speaker.
