Network audio testing system and network audio testing method thereof

摘要

A network audio testing system and a network audio testing method thereof for testing the performance of a network communication system during communication are disclosed. The system includes a processing system and a sound simulation device. The processing system is for generating a near-end simulation signal and a far-end simulation signal. The sound simulation device is for receiving and making a near-end simulation sound. The near-end simulation sound is received by a microphone of the network communication system to generate a first test signal. The processing system further simultaneously makes the sound simulation device sounding the near-end simulation sound and a speaker sounding a far-end simulation sound to obtain a second test signal. The processing system compares the first and the second test signal to obtain an attenuation degree of the near-end simulation signal and a residual energy of the far-end simulation signal.
