1 Introduction
Thank you for purchasing the AccuScreen PRO handheld Otoacous-
tic Emissions and Automated ABR Screener.
This manual is your guide to the use and maintenance of your
AccuScreen PRO.
We strongly recommend that you read it carefully through before
using your AccuScreen PRO for the first time.
We also recommend that you take particular note of the cleaning and
maintenance instructions. Failure to use and maintain the Accu-
Screen PRO correctly may void your warranty.
1.1 The AccuScreen PRO
The AccuScreen PRO is a fast, reliable, easy to use, and lightweight
hearing screener, optimised for neonatal screening. The AccuScreen
PRO closes the gap between electrophysiological assessment, which
is time-consuming and expensive, and behavioural observation.
The AccuScreen PRO uses TEOAE (Transiently Evoked Otoacoustic
Emissions) and DPOAE (Distortion Product Otoacoustic Emissions)
technologies, which are highly effective for neonatal hearing screen-
ing. Otoacoustic Emissions measure cochlear mechanics and indi-
cate whether the cochlea is functioning correctly or not. Children's
emissions are typically strong, which makes them easy and fast to
detect. Emission strength usually decreases with age.
Automated ABR (Auditory Brainstem Response) is also available in
the AccuScreen PRO. This technology measures responses to sound
in the auditory pathways. It provides a valuable supplement to TE-
OAE and DPOAE screening, and is an essential tool for screening of
infants at risk of hearing loss.
The simple, yet reliable technology ensures that hearing loss can be
detected, and intervention can be implemented, at an early age.
With early intervention, hearing-impaired children are given the
possibility of developing normal speech and language skills.
