SUMMARY This flimsy was developed to document the work being accomplished by the FAA to assess alternatives for providing PNT services when GNSS is not available due to RFI. Purpose This paper will summarize the scope and initial results of an alternative analysis being performed by the Federal Aviation Administration (FAA), Navigation Services Directorate(More)
OBJECTIVE To assess the feasibility of obtaining transient-evoked otoacoustic emissions (TEOAEs) directly in the nursery, to examine the nature of failures in this population, and to determine the time requirements for this test relative to the auditory brain stem response (ABR). DESIGN TEOAEs and ABRs were recorded from 149 ears, at bedside, in the(More)
The records of 1087 full- and pre-term infants with normal hearing were reviewed for auditory brain-stem response (ABR) abnormalities. Subjects were classified according to various complications common to the newborn. A logistic regression analysis was performed in order to determine the risk of incurring ABR deviations associated with specific diagnoses in(More)
Bilateral ABRs were recorded from 452 infants 32-45 weeks conceptional age. Differences in laterality, gender and appropriateness for gestational age were investigated in order to increase our understanding of developmental processes in early life. Rate effects were also studied in a subsample of infants (145 ears). All subjects were free of conditions(More)
Average auditory brain-stem responses (ABRs) evoked by left and right ear stimulation of varying intensities were recorded from ipsilateral and contralateral scalp placements in human neonates. Subjects included pre-term infants, healthy full-term infants and high risk, full-term infants. Pre-term infants were classified into 4 age groups ranging from 29 to(More)
The Neurological and Adaptive Capacity Score (NACS) and the auditory brainstem response (ABR) are measures that, respectively, provide neurobehavioral and neurophysiological information regarding the status of the central nervous system (CNS) in the neonatal period. We evaluated these measures as indices of CNS functioning in 15 neonates born at risk for(More)
