OBJECTIVE To address the question of whether, on a population level, early detection and amplification improve outcomes of children with hearing impairment. DESIGN All families of children who were born between 2002 and 2007, and who presented for hearing services below 3 years of age at Australian Hearing pediatric centers in New South Wales, Victoria,(More)
OBJECTIVE The aim of this study was to compare conventional processing with nonlinear frequency compression (NLFC) in hearing aids for young children with bilateral hearing loss. METHODS Sixty-four children aged between 2 and 7 years with bilateral hearing aids were recruited. Evaluations of cortical responses, speech intelligibility rating, consonant(More)
OBJECTIVE To determine the influence of choice of prescription and other child-, family- and intervention-related factors on speech, language, and functional performance of hearing-impaired children by three years of age. DESIGN AND STUDY SAMPLE A randomized controlled design was implemented as part of a population-based, longitudinal study on outcomes of(More)
OBJECTIVE To examine the impact of prescription on predicted speech intelligibility and loudness for children. DESIGN 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(More)
OBJECTIVES This paper compares language development and speech perception of children with bimodal fitting (a cochlear implant in one ear and a hearing aid in the opposite ear) or bilateral cochlear implantation. METHODS Participants were children enrolled in the Longitudinal Outcomes of Children with Hearing Impairment study. Language development was(More)
Lipoprotein(a) (Lp(a)) and apolipoprotein(a) (apo(a)) phenotypes as genetic markers for coronary heart disease (CHD) have been the focus of great interest in recent times. Included in this study were four Australian populations comprising 348 Anglo-Celtic Melburnians (157 men and 191 women), 339 Chinese Melburnians (169 men and 170 women), 402 South Asian(More)
OBJECTIVE To determine the effect of nonlinear frequency compression (NLFC) on children's development of speech and language at three years of age. DESIGN A randomized controlled trial was conducted as part of the population-based longitudinal study on outcomes of children with hearing impairment (LOCHI). Participants were randomly assigned to fitting(More)
Hearing loss in children is detected soon after birth via newborn hearing screening. Procedures for early hearing assessment and hearing aid fitting are well established, but methods for evaluating the effectiveness of amplification for young children are limited. One promising approach to validating hearing aid fittings is to measure cortical auditory(More)
OBJECTIVE We investigated the factors influencing speech perception in babble for 5-year-old children with hearing loss who were using hearing aids (HAs) or cochlear implants (CIs). DESIGN Speech reception thresholds (SRTs) for 50% correct identification were measured in two conditions - speech collocated with babble, and speech with spatially separated(More)
OBJECTIVES Universal newborn hearing screening has been implemented to detect permanent childhood hearing loss (PCHL) early, with the ultimate goal of improving outcomes through early treatment. However, there is disagreement between studies on the size of this benefit and in some cases whether it is significantly different from 0. There have been no(More)
