摘要

For sound source localization in cabin spaces, the ambient noise and reverberation have significant impact on traditional source localization algorithms and these algorithms and the array are usually complex. Therefore, we proposed a source localization method based on dual-channel spatial impulse response matching. A series of source localization experiments were carried out in a real room, and the performance of the method under different dimensions of sounding devices, SNR and reverberation were investigated. The results and their analysis show preliminarily that sound devices have high spatial resolution while satisfying the requirement of the radiated acoustic energy, and the smaller the size, the smaller is the error range which corresponds to higher spatial resolution; when the SNR is greater than 2 dB, spatial resolution in common room is 15 cm; spatial internal reverberation degree has a small effect on localization accuracy; when the sound source moves slowly, this method also has a good localization effect.
