A new procedure for fitting nonlinear hearing aids (National Acoustic Laboratories' nonlinear fitting procedure, version 1 [NAL-NL1]) is described. The rationale is to maximize speech intelligibility while constraining loudness to be normal or less. Speech intelligibility is predicted by the Speech Intelligibility Index (SII), which has been modified to(More)
OBJECTIVE This study aimed to investigate 1) how a hearing aid needs to be adjusted for an adult who uses a cochlear implant in the contralateral ear; 2) whether the use of a hearing aid with a cochlear implant leads to interference; and 3) whether adults derive binaural benefits from using a hearing aid with a cochlear implant for speech perception,(More)
Two experiments were conducted to examine the relationship between audibility and speech recognition for individuals with sensorineural hearing losses ranging from mild to profound degrees. Speech scores measured using filtered sentences were compared to predictions based on the Speech Intelligibility Index (SII). The SII greatly overpredicted performance(More)
OBJECTIVE The aim of this study was to investigate 1) whether a hearing aid needs to be adjusted differently depending on whether a child wears a cochlear implant or another hearing aid in the contralateral ear; 2) whether the use of a hearing aid and a cochlear implant in opposite ears leads to binaural interference; and 3) whether the use of a hearing aid(More)
This study was aimed at determining the effect of auditory experience on binaural benefits from using a cochlear implant and a hearing aid in opposite ears. Eighteen children were evaluated using tests of speech perception, horizontal localization, and functional performance when they used either a cochlear implant alone (CI) or a cochlear implant with a(More)
The Parent's Evaluation of Aural/Oral Performance of Children (PEACH) was developed to evaluate the effectiveness of amplification for infants and children with hearing impairment by a systematic use of parents' observations. The PEACH was administered to 180 parents (one parent of each of 90 children with normal hearing that ranged in age from 0.25 to 46(More)
OBJECTIVE This paper examines why more audibility is not always better than less audibility if hearing-impaired people are to best understand speech. DESIGN We used speech perception data from 14 normally hearing and 40 hearing-impaired people to quantify the contribution of audibility to speech intelligibility. The quantification revealed that the(More)
AIM The aim of this paper was to summarize the binaural advantages for sentence perception in noise and sound localization obtained by children and adults who wore a cochlear implant (CI) and a hearing aid in opposite ears (bimodal hearing devices). PATIENTS AND METHODS We evaluated the speech perception and sound localization ability of 29 children and(More)
Finding ways to evaluate the success of hearing aid fittings in young infants has increased in importance with the implementation of hearing screening programs. Cortical auditory evoked potentials (CAEP) can be recorded in infants and provides evidence for speech detection at the cortical level. The validity of this technique as a tool of hearing aid(More)
This paper reports interim findings of a prospective study that examines longitudinal outcomes of early- and later-identified children with hearing impairment in Australia. Eighty-seven children with cochlear implants were assessed using the Preschool Language Scale at one or more intervals. Results demonstrated that children who received a cochlear implant(More)
