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.
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.
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.
