Abstract :
In this report, an experiment on noise detection in Motorola Lab was shown. And then it was estimated the noise power ratio under various noise types based on MSOS algorithm and VAD algorithm respectively. The result showed that the MSOS algorithm is found to be a better approach in terms of estimating the noise power ratio between two microphone channels than the VAD algorithm.
