  • Publication number: 20130243204
    Abstract: A sound quality testing method and system test sound quality of a network-based communication device. The method includes connecting the network-based communication device to a test host through the Internet; sending a testing signal from the test host to the sound receiving unit for generating an audio packet signal; sending the audio packet signal from the sound receiving unit to the test host through the Internet to produce a first test result; sending a test packet signal from the test host to the network-based communication device through the Internet to enable the network-based communication device to generate a speaker signal; receiving and analyzing the speaker signal by the test host to produce a second test result; and evaluating sound quality of the network-based communication device by the test host based on the first test result and the second test result.

  • Publication number: 20130236024
    Abstract: A sound quality testing device for testing a communication apparatus has a sound generating unit and a sound receiving unit. The sound quality testing device includes a carrying unit, a first testing module, and a second testing module. The carrying unit carries the communication apparatus. The first testing module generates and sends a sound signal to the sound receiving unit. The second testing module receives a sound-generating signal generated by the sound generating unit. The sound quality testing device provides a standardized simulation testing environment having low or no noise signals, such that the communication apparatus can be tested precisely and steadily in terms of sound quality, such as volume, frequency responses, and harmonic wave distortion.
