OBJECTIVE To determine the effectiveness of auditory steady-state response (ASSR) as a measure of hearing sensitivity in young children suspect for significant hearing loss. DESIGN Within-subject comparisons of click auditory brainstem response (ABR) thresholds and ASSR thresholds. SUBJECTS The study population comprised 42 children suspect for hearing loss and subsequently referred for hea...

Ž . The Available Bit Rate ABR service in ATM networks uses end-to-end rate-based flow control to allow fair and w efficient support of data applications over ATM networks. One of the architectural features in the ABR specification ATM x Forum, ATM Traffic Management Specification Version 4.0, April 1996 is the Virtual SourcerVirtual Destination Ž . VSrVD option. This option allows a switch to ...

Auditory brainstem response (ABR) thresholds to air- and bone-conducted clicks were investigated in 40 full-term neonates. Subjects were divided into two groups of 20 according to postpartum age: less than 48 hours and between 49 and 96 hours. Mean ABR thresholds to air- and bone-conducted clicks for neonates less than 48 hours postpartum were 14.5 dB nHL (51.5 dB peak SPL) and 1.8 dB nHL (36.8...

OBJECTIVE The aim of this study was to determine the air-bone gaps in adults with mixed-type hearing loss using air-conduction auditory brainstem response (ABR) latencies. MATERIALS AND METHODS Thirty adults with mixed-type hearing loss (study group) and 30 adults with normal hearing (control group) were included in this study. Before performing ABR measurements, ear, nose, and throat examina...

OBJECTIVE Our goal was to determine the cost-effectiveness of including auditory brainstem response (ABR) testing in a screening protocol for the diagnosis of vestibular schwannoma (VS) in patients with asymmetric auditory symptoms at the Christian Medical College and Hospital, Vellore, India, where, commonly, patients with VS have tumors greater than 2 cm at the time of diagnosis. METHODS Ni...

abstract:background : hyperbilirubinemia is one of the most common cause of congenital sensory neuronal hearing loss. these patients are screened by auditory brainstem response (abr) test at bilirubin levels higher than 1% of gestational weight. aim: to determine whether hyperbilirubinemia less than 1% of gestational weight could induce hearing loss and abnormal auditory brainstem response (abr...

In an ad-hoc mobile network where mobile hosts (MHs) are acting as routers and where routes are made inconsistent by MHs‘ movement. In associativity-based routing protocol (ABR) where a route is selected based on nodes having associativity states that imply periods of stability. In this manner, the routes selected are likely to be long-lived and provides maximum throughput. In this paper we cre...

Considering the high-speed data transfer by the ABR service class in a wireless ATM network, we investigate the impact of forward and backward hard handover protocols on the performance of the three rate-based ABR flow-control schemes Explicit Rate Indication for Congestion Avoidance (ERICA+), Fuzzy Explicit Rate Marking (FERM) and a new promising adaptation of FERM, called FERMA. We evaluate t...

Auditory brain-stem responses (ABRs) were studied in 66 subjects with severe head trauma. Middle latency responses (MLRs) were also recorded in 22 of them. Patients were carefully selected to avoid conditions such as pre-existing or acute deafness, hypothermia or ethanol intoxication. In order to evaluate the usefulness of potentials in predicting recovery, patients were classified according to...

OBJECTIVES To examine the relationship between speech intelligibilities among the similar level of hearing loss and threshold elevation of the auditory brainstem response (ABR). METHODS The relationship between maximum speech intelligibilities among similar levels of hearing loss and relative threshold elevation of the click-evoked ABR (ABR threshold - pure tone average at 2,000 and 4,000 Hz)...
