Hearing screening is a test method for early detection of hearing impairment in infants. It can help doctors or professionals to evaluate the hearing function of infants so as to take early intervention measures.
Hearing screening usually includes the following steps:
1. natural observation: doctors or professionals will observe the baby's reaction, such as the reaction to sound, language or facial expressions. This can help them initially judge whether the baby has hearing problems.
2. Auditory reflex test: Doctors or professionals will use some specific stimuli, such as sound or touch, to observe the baby's auditory reflex. These reactions can provide information about whether the baby's auditory system is working properly.
3. Automatic hearing screening: This is a common hearing screening method, which records the baby's reaction by playing a series of sound or voice samples. These samples can include sounds with different frequencies and volumes to evaluate the baby's perception of different sounds.
4. Auditory evoked potential test (ABR): This is a more accurate hearing screening method, suitable for older infants and children. It measures the brain's response to sound stimulation by placing electrodes on the baby's scalp. This test can provide more detailed information to help doctors determine the baby's hearing condition.
It should be noted that the above method is only one of the common hearing screening methods, and the specific screening methods may be different due to different regions and medical institutions. If you have any questions about your baby's hearing, it is recommended to consult a professional doctor or hearing expert, who will provide you with the most suitable screening methods and suggestions according to the specific situation.
