The Digital Auditory Integration Training Instrument is also a type of sensory integration therapy. This method corrects dysfunctions in the processing of sound in the subject’s auditory system and stimulates brain activity by having the subject listen to music modulated by an auditory integration trainer, i.e., by using the trainer to decide whether to filter a certain audio or to lower the high or low frequencies in the music based on the patient’s auditory test, thereby improving the subject’s language disorders, interaction disorders, emotional disorders and behavioral disorders. Most children with autism (autism) develop a preference for music. Although they are indifferent to the outside world and some are even non-verbal, they mostly show great interest in music, and some children even have an extraordinary musical sense and superb sound discrimination ability. When the sound signal is transmitted to the thalamus and cortical system through the nerve fibers of the auditory organs, the basic elements of pitch, intensity and timbre in music can directly pass through the subcortical structures such as the thalamus, causing the brain organism to react autonomously, and all kinds of sounds take time as the carrier and show their own orderly sound rhythms in the process of time, and this sound rhythm and all living objects in nature produce a heterogeneous The rhythm pattern and tune system in music has a wonderful commonality with the characteristic rhythm of human body to a large extent. The effects of digital auditory integration training are extensive and usually occur weeks or months after training, or during the training process. The following symptoms may improve after treatment: 1. increased attention to auditory stimuli; 2. increased comprehension of speech; 3. increased average length of speech; 4. louder speech; 5. decreased imitation of speech; 6. increased interest in communication; 7. increased eye contact; 8. increased appropriate social behavior and increased ability to accept change; 9. Increased perception of the presence of others or tolerance of others; 10. Increased desire to interact with others; 11. Decreased burnout, decreased sitting and looking at others; 12. Decreased stereotypic and self-stimulatory behaviors; 13. Decreased impulsive restlessness; 14. Decreased tantrums; 15. Decreased aggressive behavior; 16. Increased memory for everyday information; 17. Increased numeracy; 18. Decreased inattentiveness; 19. In order to better evaluate the effect of auditory training, patients need to have an EEG and a pure tone audiogram before and after the training.
