Hearing loss is a common birth defect in babies. It can affect about 1 to 3 out of every 1,000 babies born.
While often medical professionals are unable to determine what caused the hearing loss, there are some factors that can lead to the defect.
Babies who are born prematurely or who stayed in the neonatal intensive care unit can be prone to hearing loss.
Babies who have been exposed to very loud noises are also at-risk.
A family history can also lead to hearing loss, as can numerous ear infections, other infections and certain medications.
