Screening for neonatal and infant deafness in Europe in 1992

Many methods of screening for hearing impairment are available. The aim of our study was to determine which ones were really used in 1992. At the request of the British Audiology Society, we conducted an inquiry into the organization of screening for deafness in neonates and infants in Europe. In practice all 6-9 month-old infants are tested with behavioural tests in every country. For the neonates, generally only those at risk for hearing-impairment (about 5%) were tested. The most widely used tests were behavioural ones. Only specialized centers used transient evoked otoacoustic emissions (TEOAEs). This last test assesses the active mechanical properties of the cochlea and allows detection of even mild or unilateral sensorineural deafness.
