You can do your own testing based on the following Adult “Hearing Impairment Self-Checklist”:
At 3-6 months, he will not turn his head or use his eyes to search for the source of the sound that appears;
Over 24 months, the child’s language pronunciation is abnormal or incorrect, slow or no response to the sound, such as not hearing a bird, and no response to the phone ringing or door ringing, etc.
If the above situation is found, it reflects that there may be problems with the child’s hearing, and it is recommended that parents take their children to see a doctor in time.
