Experiment of SAS based on LabVIEW

In order to detect the sound signal more real-time and intuitive, a sound acquisition system (SAS) based on data acquisition card is designed. The USB data acquisition card is chosen as the hardware of SAS and the laboratory virtual instrumentation engineering workbench (LabVIEW) is selected as the software of SAS. Finally, the experimental results show that the SAS combined with data acquisition card and Labview software can monitor sound signals in real time, which can be widely used in various field of sound detection.
