  • Publication number: 20230160993
    Abstract: A method and system for generating a target map for training a neural network and obtaining a sound source map regardless of the maximum number of sound sources, having a short computation time for inference, high spatial resolution and high sound source accuracy. The method includes generating grids each having a spacing within a given range at positions where sound sources are present in order to form a sound source map, calculating a result value for each of coordinates of the grids so that the result value is a local maximum at the position of a sound source and the result value decreases depending on the distance from the sound source, arranging the result values at positions on matrices corresponding to the respective coordinates of the grids, and generating a target map having an image form by using the result values arranged in on the matrices.
