The auditory training for deaf children is to help deaf children make full use of residual hearing to recognize, identify, remember and understand various sounds, especially speech sounds, repeatedly, to establish correct auditory concepts, and to improve auditory sensitivity while developing interest and habit of listening, i.e., to improve auditory ability for the purpose of hearing and interacting with others. The content includes: The development of the ability to judge the presence or absence of sound Consciously create or use various sounds (including speech sounds) to make the deaf child feel the presence of sound, develop the ability of auditory perception, and teach the deaf child to use the table. This is the basis of auditory training. The development of auditory attention skills fully mobilizes the deaf child’s interest in listening to various sounds, especially speech sounds, and guides the awareness and skills of listening to other people’s questions and conversations, gradually developing good listening habits. The development of listening habits is not only an important part of the auditory training, but also runs through the whole process of auditory training. The development of the ability to distinguish different sounds Through demonstrations, comparisons, and manipulations, we help deaf children to distinguish different sounds, especially speech sounds and what they represent. For example, what sound is being made? What or who is making the sound? What does it mean? Is the sound loud or small? Is it fast or slow? Is it far or near? Is it right or wrong? In order to develop the deaf child’s auditory orientation, auditory discrimination, auditory memory, and the ability to form auditory concepts. In particular, it is important to emphasize that differentiation of speech sounds is the main component of auditory training, which is more practical for deaf children. Development of selective listening ability To practice listening to learned and familiar contents with certain background sounds in order to improve the deaf children’s ability to capture useful information under the noise of daily environment. Development of auditory feedback skills Help deaf children gradually learn to listen to their own pronunciation, expression and use of language correctly and appropriately, and to correct errors in a timely manner.
