Causes of Hearing Loss
Hearing loss is a common birth defect, affecting about 1 to 3 out of every 1,000 babies. A number of factors can lead to hearing loss, and about half the time, no cause is found.
Hearing loss can occur if a child:
was born prematurely
stayed in the neonatal intensive care unit
had high bilirubin requiring a transfusion
was given medications that can lead to hearing loss
has a family history of childhood hearing loss
had complications at birth
had frequent ear infections; had infections such as meningitis or cytomegalovirus
exposed to very loud sounds or noises even of brief duration
