The development of auditory examination technology and the emergence of a variety of new instruments, early detection of deaf children.

A total of 152 external ears, ranging from 2 hours to 31 days after birth, had no abnormalities in the tympanic membrane, including 14 preterm infants, weighing 1290 to 4085 grams at birth. The instrument used is a doll with a built-in sound generator of a built-in room. Fetal endocardial tone including maternal aorta, umbilical cord noise, bowel sounds, fetal heart sounds (144 beats / min), maternal heart sounds, etc., the frequency from 400Hz to 4000Hz. When the child was seized crying, 30cm away from the nasal root put
