Hearing loss can affect the hearing and speech development of a patient, thereby causing language disorders. In severe cases, the social ability and the psychological development of the people are affected. Therefore, the hearing loss should be diagnosed, treated and recovered as early as possible.

The diagnosis of hearing loss is mainly done by stimulating the auditory system by giving sounds of certain frequency and intensity to judge the extent of hearing loss. The hearing test has objective auditory evoked potential detection and pure tone hearing test, the objective electrophysiological detection is to send out sound with certain frequency and intensity to stimulate auditory organs through an instrument and then collect the cerebral cortex potential of a hearing-impaired person, but because brain wave signals are complex and have large interference, and the auditory evoked potential detection can only objectively reflect the conditions of auditory nerves and the cerebral cortex, the result obtained by the auditory evoked potential detection has no frequency characteristic, and the accurate data of the hearing loss of the hearing-impaired person can not be obtained. Pure tone hearing tests are tests of the entire auditory pathway (external ear-middle ear-inner ear-auditory nerve), but they require that the subject be fitted and feedback be given based on the signal being tested, such as: and (5) raising hands to indicate, and pressing a feedback key to enable a tester to receive a feedback signal and give a judgment.

Due to limited comprehension and self-restraint of young children, there may be an assessment that individual young children are not matched to a pure tone hearing test. Therefore, the subjective reaction of the tested children needs to be observed in the testing process, but the requirement on personnel is high, on one hand, the requirement on the number of the personnel is needed, and multiple people are needed to cooperate with each other to work; on the other hand, the requirements on the ability of the personnel are high, for example, the observation ability of facial expressions and body movements is good, the corresponding recording ability is strong, and the like. Therefore, the labor cost for carrying out pure-tone hearing test on the young children is higher, and the actual operation is more difficult.
