Common methods for sound source localization heavily rely on the accuracy of measurement data．When errors are present，they can lead to unsolvable equations．A new sound source localization method，known

as line-surface localization，utilizes a three-dimensional coordinate system to determine the position of the sound source by finding the intersection between surfaces and lines．This approach reduces the number of time delay measurements required and effectively avoids issues related to the inability to solve for the sound source position due to measurement errors．Additionally，controlling the shape of the stereo sound array can enhance

measurement accuracy and optimize the processing of noise and sound source signals．With this model，effective sound source localization can still be achieved within a certain range，even in the presence of errors．
