Embodiment Construction

[0036] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] FIG. 1 is a schematic diagram of a test network in a test method for an audio communication system according to an embodiment of the present invention. As shown in Figure 1, the audio communication system 100 to be tested includes: a first communication terminal (first communication device) 101 and a second communication terminal (second communication device) 102, wherein the test is performed between the first communication terminal 101 and the second communication terminal It is performed when the communication terminals 102 communicate with each other. Exemplarily, the audio communication between the first communication terminal 101 and the second communication terminal 102 may be point-to-point, or may be audio communication through a tra...

Abstract

The invention provides a test method and a device for an audio communication system, the audio communication system includes a first communication terminal and a second communication terminal, wherein, the method includes: first step, a first video signal pre-produced is imported into the first communication terminal under the condition that the first communication terminal is communicated with the second communication terminal; second step, frequency and / or amplitude of a second video signal are / is imported by the second communication terminal; third step, the frequency and / or the amplitude between the first video signal and the second video signal are / is compared with each other, and frequency different and amplitude different of both are judged whether to be in the range of pre-established inaccuracy or not, the audio communication system is decided to normally work if the difference is in the range of the pre-established inaccuracy; else, the video communication system is decided to work abnormally. The device includes: a signal import module, a signal export detection module and a comparison module. The invention can eliminate the inaccuracy of a subjective test in a prior art depended on man-made subjective feeling.

Description

technical field [0001] The invention relates to the field of audio testing, in particular to a testing method and device for an audio communication system. Background technique [0002] In the prior art, generally speaking, the audio test of an audio communication system such as a multimedia communication system is realized through people's auditory experience, and must rely on people's subjective feelings, which brings many uncertain factors to the test and makes the test difficult. The result is not objective enough. Moreover, due to the complex and diverse sites used by the audio system to be tested, the subjective test of user experience is always not comprehensive enough, which will lead to repeated changes in the test conclusions. Make effective suggestions for improvement. Moreover, the testing method in the prior art needs to manually test the sound for a long time, which not only causes a waste of manpower, but also results in unreliable results. Because the test...
