Infant hearing test method–Infant hearing test
The easiest way to detect hearing in infants is to observe their auditory response. Infants and young children often have blinks of sudden sound, changes in sucking movements, auditory-heartbeat reflexes, startle reactions, turning heads and other reflex actions. According to this feature, it is possible to initially estimate whether there is hearing impairment in infants and young children. However, infants and young children have individual differences in their development, often requiring more detailed examinations and using objective hearing tests. Such as acoustic impedance test, auditory brainstem response, otoacoustic reflex, multi-frequency multi-frequency steady-state evoked potential. It can be checked when the baby is quiet or after going to sleep.
Newborns are usually in a quiet environment, right60-70dBSPLThe stimuli may react. As the age of age or age increases, the hearing sensitivity gradually increases.4-7You can be right in the month40-50dBSPLThe stimuli are responsive.
