| Abstract: | Based on the 4-elements plane square array localization model and the phase time delay estimation algorithms of cross-power spectrum,a real time synchronizing sound source location system is designed with the virtual technology.The system is programmed by mixing the Matlab into the LabVIEW.A multifunctional data collect card(Advantech PCI—1714) is used as the hardware platform for instantaneous sound detection and high speed sound data acquisition.The locatable speed and precision of this system is preferable. |
