In order to evaluate the usefulness of DPOAEs for universal neonatal hearing screening (UNHS), we measured DPOAEs in 1075 normal Japanese babies at one obstetric clinic and 4 general hospitals by using ERO/SCAN DPOAE screener (MAICO). Advantages of this device are autostart and capability of quick measurement, 7seconds at default basic mode. Overall referral rate was 4% at first stage and was down to 0.8% by two-stage screening. In about half of the babies, measurement was completed within 1minute in each ear including preparation time, and 80% of that within 3minutes.We concluded that the DPOAEs are useful in the relatively small Japanese obstetric clinics and hospitals in the view points of low cost, easy operation and accuracy.However, DPOAEs are quite new method for evaluation of deafness and PASS/REFER criteria has not yet been standarlized. Therefore, we must pay a carefull attention for evaluation of deafness by this device.
