Purpose: The aims of the study were to examine the acoustic reflex screening and threshold in healthy neonates and those at risk of hearing loss and to determine the effect of birth weight and gestational age on acoustic stapedial reflex (ASR). Method: We assessed 18 healthy neonates (Group I) and 16 with at least 1 risk factor for hearing loss…

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…

To investigate the transient evoked otoacoustic emissions (TEOAE) contralateral suppression in neonates at risk for hearing loss, 55 neonates at risk for hearing loss (risk group) and 72 full-term neonates not at such risk (control group) were bilaterally tested. In all neonates, the TEOAE were recorded in two stimulation modes (linear and…

The goal of this project was to increase by 50 percent the number of children with significant hearing impairment identified by 12 months of age. Attainment of this goal was attempted through activities in three major areas: (1) replication and documentation of the benefits of a birth certificate-based screening system; (2) investigation of the…
