In this report, the result of our follow-up study of those children with mild-to-moderate hearing loss who were born before the introduction of Newborn Hearing Screening is presented. The subjects were 30 children diagnosed at Kitasato University Hospital as having hearing loss less than 70dBHL, during the period from 2002 to 2004. The average age at their first visit to the hospital was 69 months, and the average hearing threshold level was 47dB. All the subjects were found to have communication problems. Delayed language development was noted in 27, while articulation disorders were found in 20. Following our habilitative intervention, 15 subjects adopted hearing aids all day long. Within several months of habilitation, active social commitment was observed. A year later, an improvement in language development was noted. Most of the parents had some difficulty in understanding the possible problems caused by hearing loss. The apparent lack of universal use of hearing aids seemed to be due partly to the ignorance of the parents or to their economical situation. It was stressed that developing an effective program must be put in place to promote the parents' recognition of various problems surrounding children with mild-to-moderate hearing loss.
