Objective: The purpose of this study was to describe normative aspects of wideband acoustic immittance (WAI) measures obtained from healthy White neonates. Method: In this cross-sectional study, wideband absorbance (WBA), admittance magnitude, and admittance phase were measured under ambient pressure condition in 326 ears from 203 neonates (M age…

This research study aimed to explore the experiences of caregivers of children through the early hearing detection and intervention (EHDI) process in the public health care sector in South Africa. A qualitative research design was employed. Semistructured interviews were conducted with 8 caregivers from 3 different levels of service delivery in…

Purpose: The aim of this study was to develop a risk prediction model for detecting middle ear pathology in 6- to 9-month-old infants using wideband absorbance measures. Method: Two hundred forty-nine infants aged 23-39 weeks (Mdn = 28 weeks) participated in the study. Distortion product otoacoustic emissions and high-frequency tympanometry were…

Purpose: The aim of this article was to study the normal longitudinal development of wideband absorbance and admittance measures through infancy. Method: Two hundred one infants who passed the newborn hearing screen (automated auditory brainstem response) were tested at birth and then followed up at approximately 6, 12, and 18 months of age. Most…

In children with a hearing loss who receive cochlear implants (CIs) under the age of 2, regular assessments are conducted to monitor auditory and linguistic progress. However, the collection of authentic, representative, and reliable expressive language data on young children with CIs remains a challenge. The purpose of the study was to determine…

Three experiments investigated perception of audio-visual (A-V) speech synchrony in 4- to 10-month-old infants. Experiments 1 and 2 used a convergent-operations approach by habituating infants to an audiovisually synchronous syllable (Experiment 1) and then testing for detection of increasing degrees of A-V asynchrony (366, 500, and 666 ms) or by…

Infants were tested for their discrimination of changes in the melodic contour (direction of successive pitch changes) of brief melodies in the context of discernible variations in key or interval size. (PCB)

Assessed auditory temporal acuity among infants of 3, 6, and 12 months of age and adults. Gap detection thresholds were quite poor in infants. Effects of restricting the range of frequencies available for detecting gaps were qualitatively similar for infants and adults. (GLR)

British Medical Journal, 1172 Commonwealth Avenue, Boston, Massachusetts 02134. The effectiveness of current audiometric screening programs was evaluated in Scotland with 535 infants, using both conventional hearing tests and pure-tone audiometry. (Author/DLS)

Determines whether an averaged evoked potential technique using a random-v-repetitive presentation mode could be used to study infant auditory discrimination. Results showed a main effect of presentation mode with shorter latency for random v repetitive. The shortest onset latency was for random stimulus at the fast rate. (Author/DB)

Three experiments investigated four-month-old infants' capacity to perceive bimodally specified events by detecting the temporal synchrony of sound bursts with the visable impacts of surfaces. (Author/SS)

Evaluated with 12 children (9- to 25-months-old) were the efficacy and reliability of auditory stimulus-response control training and assessment procedures. (Author/LS)
