Abstract: The objective was to evaluate the language distinguishing ability of deaf children after wearing hearing aids. The effects of hearing aids was evaluated by using the national testing questions for deaf children. After 3 terms of observation, there was no evident difference at audio frequency of compensation range(P >0.05), but speech recognition score rose sharply(P<0.01). 1) After wearing hearing aids for a period, deaf children should be trained by aural language practice, and then they could gradually recover aural function. 2) Speech audiometry provides a very important evaluation index for aural language recovery training.

Key words: speech audiometry, hearing aids, speech recognition score
