Newborn hearing screening using OAE technique (TEOAE or DPOAE) is a mandatory requirement in many countries of the world, and it is performed for every newborn baby a few days after birth.
The portable aScreen system ensures fast, accurate and safe screening. The system consists of the OAE probe that can be connected to the mobile terminal using USB-C cable.
To perform the test, select the ear tip of appropriate size and attach it to the probe. Insert the probe gently into the baby’s ear canal, select the desired technique (TEOAE/DPOAE), click the Start button and get the result—PASS or REFER—in a few seconds. You can immediately print the results on the thermal printer, save them to the device memory or copy to the PC software.
aScreen comes with a set of pre-defined templates that meet the most common recording conditions (Noisy—screening, Normal—screening, Quiet—screening).
Use them or create your own to get the best results any time. Set noise level, intensity, SNR pass criteria and other parameters in the device settings.
aScreen requires no additional equipment to print the results—the mobile terminal features a built-in thermal printer for time-saving result printing.
Maximum reliability of the test results is achieved through using special noise rejection and accurate calibration technologies while thought-out user interface ensures high performance and streamlines the test.
Bluetooth interface allows exporting the data from the device to the computer with installed Neuro-Audio-Screen Manager software. This software is supplied with the device; it facilitates managing and archiving the patient database.
aScreen is supplied with a mobile terminal but it can also work with many Android-based smartphones and tablets with USB On-The-Go feature and USB-C connector. All you need is to choose a device with the screen size and battery capacity you are comfortable with.
