including simple classification

understanding and practical application. The language recognition ability

communication ability

hearing ability and communication fear were compared before and after the intervention. Results Before the intervention

there was no significant difference in language recognition ability

MHZNT and PRCA-24 scores between the two groups（P>0.05）. After the intervention

the language recognition ability and communication ability of the study group were significantly different from those of the control group（P<0.05）

the MHINT score was significantly higher than that of the control group

and the PRCA-24 score was significantly lower than that of the control group. Conclusion The intervention effect of auditory rehabilitation training on CI patients with post lingual deafness is ideal. It can improve their language and auditory ability
