Questions and answers have been memorized, sometimes verbatim, and contributed to extensive archives of old ABR test
material that become the prize possessions of many residency programs,?
The ABR test was re corded with the Intelligent Biologic Master System (Intelligent Hearing Systems; Miami) using traditional montage and recording techniques.
In this study, we evaluated patients with untreated, MRI-proven unilateral vestibular schwannomas with the use of a traditional ABR test and a determination of threshold differences for the purpose of increasing ABR sensitivity.
The ABR test
studies the electric impulses of the auditory nerve pathways from the ear in response to clicks or short bursts of sound.
published in the Journal of the American Academy of Audiology, following recommendations made in the NIH (1993) consensus statement, showed that a two-stage newborn screening program using OAE testing, followed by an ABR test
of infants who do not pass, resulted in the lowest costs per baby tested.
Impedance test results were normal, and the ABR test
showed a good response only in the right ear at 80 dB.
However, without the Clarity System, hospitals must purchase two systems to meet the NIH's recommendations of using both OAE and ABR tests
in a two-stage testing protocol for complete screening.
By combining OAE and ABR tests
into a single, truly portable device, we are leading the way for simple, advanced and reliable hearing screening.
The GSI AUDIOscreener(TM) is the first and only device to combine evoked otoacoustic emissions (OAE) and auditory brainstem response (ABR) tests in a single, handheld, PC-free unit -- providing a practical solution to the National Institutes of Health's recommendation for universal newborn hearing screening using both OAE and ABR tests
