Abstract(in English) | The direction of a sound source cannot be correctly estimated in rooms when the amount of reflected sound is more than 5-10 dB relative to the direct sound.We examined this results from how mirror images look.We found that massed mirror images which behave as one source increase the error when a linear microphone array is positioned parallel to a wall and the floor in parallelepiped rooms.We also show that with the cases when the linear array is not placed parallel to a wall and with circular array case,mirror images look more dispersed,which resulted in improvement of the source direction estimation performance. |
