Note. HA = Hearing aid
a, b
Fourteen children’s PTAs fell outside the criterion range (25–75 dB HL). The research team made some exceptions at both ends of the range, due to unique audiological or medical circumstances (e.g., hearing loss in low or high frequencies only, fluctuation due to otitis media with effusion or enlarged vestibular aqueduct syndrome).
c
College refers to a four-year university setting.
