Abstract
We describe what characteristics an independent component analysis can extract from leakage sounds. The learning algorithm of a network was an information-maximization approach proposed by Bell and Sejnowski. We applied the independent component analysis to the leakage sound. After the learning, most of the basis functions that are columns of a mixing matrix were localized in frequency. Furthermore, there were some basis functions to extract the feature of leakage sound. From these results, we confirmed that the application of independent component analysis to the signal processing of the acoustic signal was effective.
