| Abstract: | With the development of VOIP system, the sound quality it can produce on LAN has attracted attention as much as possible.This paper illustrates the requirements for network capability on the basis of VOIP sound features and three models on the evaluation ofsound quality. It tests the sound quality of VOIP in Wuhan University of Science and Technology Zhongnan Branch through professionalVQT equipment and gives a brief introduction to the testing schema. |
