s11717 Neural network approach to analyze spatial sound localizationKalle Palomäki, Ville Pulkki, Matti KarjalainenLaboratory of Acoustics and Audio Signal Processing Espoo Finland
Self-organizing maps (SOM) and multilayer perceptron (MLP)
neural network approaches are applied to the evaluation of spatial
discrimination of real and virtual sound sources. Neural networks are
trained with localization cues computed using a binaural model. The
ability of the models to simulate human perception of spatial sound is
analyzed. Both SOM and MLP showed relatively good ability for
generalization when tested with test data from real sources not included
in the training data set. Both models were also capable of describing
localization blur of virtual sources though still further analysis is
needed to find out how well our models correspond to real human auditory
localization. The motivation of this study has been to search for methods
and techniques to evaluate the quality of spatial sound reproduction
