Abstract :
The direction of a generated sound source can be estimated by humans using the time difference between both ears and the characteristics of the sound. However, it is very difficult to create an estimation system using a computer and two microphones. In this study, we propose a novel sound source direction estimation method, in which the feature difference of two recorded microphone signals is used. As a result, an average correct estimation rate of 96% was obtained in determining the location of 11 kinds of object sounds
