The substance of the speech communication interference result evaluation is the sound quality evaluation, the sound quality evaluation belongs to the category of the speech signal processing, This text will be apply in the speech quality various parameters with objective evaluation. the sense of hearing feeling analyzes how these models imitate the person knows to carry on the sound quality evaluation from the similar person's sense of hearing behavior ,expecting to get a more consistent result with the subjective sense of hearing.After the theories model build up, this text terminology test them if they can adapt to sound communication interference data acquired from the outfield experiment and emulated data. However, the listener usually makes use of the experience of many-year-backgrounds and the high intelligence while carrying on evaluations, which are hard to emulate in the model description. What we can do is to make use of the acquisition information to make a basic right of evaluation. This text builds up the sound quality evaluation parameter function valuation system, examines each parameter with the data acquired from the outfield experiment, uses the related coefficient and the standard square as the measurements,, looks for the objective parameter applicable tot the interference result assess most.What we can see from the experiment result is: the objective measure which considered the ear sense of hearing characteristic is obviously better than other parameters, so the objective sound quality evaluation parameter bases on the ear sense of hearing characteristic get probably consistent result with subjective evaluation. The MFCC model gets all good result to the emulated data and the data acquired from out-field experiment. It is a kind of parameter with good function whose ability of orientation environment is strong.For satisfying the demand that the outfield experiment, according to the research result of the text, the assess method is built up .The method will be used in the speech communication interference result experiment.
