Abstract
In the actual measurement, the acoustic signal is often measured under the mixture of several noise sources. We propose a probabilistic estimation method for extracting the objective noise by using Independent Component Analysis. The effectiveness of this method has been experimentally confirmed by applying it to the actual acoustic data.
