乳幼児聴力検査の適応年齢に関する一考察 Hearing Tests Recommended for Specific Ages of Infants
In infants with no signs of mental retardation,337 hearing tests were performed for 4 months. This report reveals the recommended methods of testing for specific ages.<BR>The results showed that BOA (behavioral observation audiometry) was recommended for infants from birth to 12 months of age, COR (conditioned orientation response audiometry) for infants aged 6 months to 2 years, Peep show testing without headphones for infants aged 3 to 4 years and with headphones for infants aged 4 and a half to 6 and a half years, and air-bone conduction testing for infants aged 6 years.<BR>In the case of some infants with severe to profound hearing loss, the results differed from those of normal to mild hearing-impaired infants. A hearing test at any age can help to detect hearing loss. The earlier hearing loss is detected, the sooner a child may be assisted.
