Second, the response is slow. Parents can call their children to see if they are unresponsive or unresponsive. Moreover, hearing-impaired children usually have the problem of poor position judgment. If they call on the child's right side, but the child can't turn his head or body to the right side accurately, but turns in the opposite direction or other directions, it may also be hearing impairment.
Third, the pronunciation is not accurate. Some hearing-impaired children may also have the phenomenon of poor development or unclear speech. In this case, some parents mistakenly think that the child's vocal organs are abnormal, which is actually a symptom of sensorineural deafness. Usually, children will be inattentive and often answer irrelevant questions raised by others.
