Patent ID: 8675821

Claim:
A network audio testing system for testing performance of a network communication system during communication, the network communication system having a speaker and a microphone, the network audio testing system comprising: a processing system connected with the network communication system via a network environment for generating a near-end simulation signal and a far-end simulation signal, wherein the waveform of the near-end simulation signal is different from the waveform of the far-end simulation signal; a sound simulation device electrically connected with the processing system for receiving the near-end simulation signal and making a near-end simulation sound, the near-end simulation sound being received by the microphone to obtain a first test signal transmitted to the processing system; and a memory module electrically connected with the processing system for storing the first test signal, wherein the processing system further simultaneously makes the near-end simulation sound using the sound simulation device and transmits the far-end simulation signal to the speaker to make a far-end simulation sound, the microphone receives to obtain a second test signal transmitted to the processing system, the processing system compares the first test signal with 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.
