Based on clinical records, 44 children 80 (10%) were diagnosed with auditory neuropathy spectrum disorder. There were 107 children 81 (24%) reported to have additional disabilities. At 3 years of age, 317 children (70%) were 82 hearing-aid users and 134 children (30%) used cochlear implants. Based on parent reports, 83 about 71% used an aural/oral mode of communication, and about 79% used English as the 84 spoken language at home. Children's performance scores on standardized tests administered 85 at 3 years of age were used in a factor analysis to derive a global development factor score. 86 On average, the global score of hearing-impaired children was more than one standard 87 deviation (SD) below the mean of normal-hearing children at the same age.

A between-group comparison of speech intelligibility index (SII) and loudness, based on hearing aids fitted according to NAL-NL1, DSL v4.1, or DSL m[i/o] prescriptions. A within-group comparison of gains prescribed by DSL m[i/o] and NAL-NL2 for children in terms of SII and loudness. Participants were 200 children, who were randomly assigned to first hearing-aid fitting with either NAL-NL1, DSL v4.1, or DSL m[i/o]. Audiometric data and hearing-aid data at 3 years of age were used. On average, SII calculated on the basis of hearing-aid gains were higher for DSL than for NAL-NL1 at low input level, equivalent at medium input level, and higher for NAL-NL1 than DSL at high input level. Greater loudness was associated with DSL than with NAL-NL1, across a range of input levels. Comparing NAL-NL2 and DSL m[i/o] target gains revealed higher SII for the latter at low input level. SII was highe...
