What is the normal rate of hearing screening for newborns?

Patient's question:

My baby is seven days old today, and the hearing screening still hasn't passed. Although the doctor told us not to worry, I'm still very worried and don't know what to do. My heart always feels heavy. I want to ask, what is the pass rate for newborn hearing screenings?

Doctor's answer:

Statistics show that the choice of initial screening time for newborns at 24, 48, and 72 hours after birth was compared and observed. The initial screening pass rates were 58.5%, 80.0%, and 95.5%, and 65.0%, 86.7%, and 92.3%, respectively. Newborns who did not pass the initial screening were re-screened after 42 days, with pass rates of 97.8% and 94.02%. As age increases, the pass rate of hearing screening gradually improves, especially for newborns who did not pass the initial screening. The 42-day retest pass rate for these newborns exceeded 90%. This indicates that the pass rate of newborn hearing screening is positively correlated with the child's age. Therefore, parents do not need to worry too much.
