ABSTRACT
Most hearing screening programs have historically targeted children with moderate
or more severe bilateral hearing loss. Children with unilateral or mild bilateral
permanent hearing loss represent a substantial proportion of all children with hearing
loss, and there are serious negative consequences for these children if they are not
identified early and given appropriate help. Many children, particularly those with
unilateral or mild bilateral hearing loss, acquire hearing loss after the newborn
period. Although virtually all newborns are now screened for hearing loss before leaving
the hospital, there are very few opportunities for periodic hearing screening after
the newborn period. Effectively identifying those children who have late-onset loss
or who are missed during newborn hearing screening will require modifying some of
the procedures currently employed in hospital-based newborn hearing screening programs,
as well as establishing better hearing screening procedures for early childhood and
elementary school programs. Existing state Early Hearing Detection and Intervention
systems are a resource for establishing and improving screening programs for infants
and children with unilateral or mild bilateral hearing loss.

1 NHANES analysis uses definitions of “slight” (16 to 25 dB HL) and “mild” (26 to 40
dB HL) for low-frequency hearing loss (pure-tone average 0.5, 1, and 2 kHz) and high-frequency
hearing loss (pure-tone average 3, 4, and 6 kHz).
2 Recording epochs of 20 to 25 milliseconds are necessary for adequate ABR threshold
detection measures in infants, especially when tonal stimuli are used.[45 ]
3 Bone-conduction testing should be completed if air-conduction thresholds are greater
than 20 dB nHL.[45 ]
