Getting to Know Your AVANT ARC
Intended Use Statement:
The MedRx AVANT ARC is an electronic instrument containing an audiometer intended to
diagnose hearing loss in adults and children. Audiograms are created and used to set the
correct gain levels of the hearing aid for various frequencies. The device also contains a REM
(Real Ear Measurement) function intended to measure sound levels directly in patient ears.
They are used in the measurement and fitting of hearing aids for adults and children. These
measurements can be done with or without the hearing instrument being worn. They are
also used for hearing loss simulation. The REM can perform Live Speech Mapping (MedRx’s
in-situ method for getting the fitting right the first time). These devices should be operated
by trained professionals with education and/or training in the field of audiometry.
Indication For Use Statement:
The MedRx Avant ARC is an audiometer and a REM (Real Ear Measurement) device
combined into one system. It is for use by professionals with education and/or training in
the field of audiometry to conduct diagnostic hearing evaluations, evaluate basic hearing
function, aid in the diagnosis of otologic disorders, as well as to evaluate the fitting of
hearing aids and for hearing loss simulation in adults and children.
The software includes targets for DSL v5.0 and NAL-NL2. A unique feature of the Real Ear
Measurement System is simultaneous, binaural Live Speech Mapping, MedRx’s in-situ
method for getting the fitting right the first time, every time. The device performs Real Ear
Measurements where measurements are performed directly on the patient's ear. These
measurements can be done with or without a hearing instrument being in place. The reason
to perform Real Ear Measurements for hearing instrument fittings is that shape and size of
an ear canal significantly influence a hearing instrument's performance. Knowing the sound
intensity outside and inside the ear enables the practitioner to determine the actual
amplification and output that the patient receives through the hearing aid and make the
appropriate adjustments.
This unit is a Type 2 AE audiometer that meets the requirements of both ANSI S3.6 and IEC
60645-1 and IEC 60645-2. These standards specify the required precision that the AVANT
ARC does achieve. Measurement uncertainty is +/- 1 dB. This device and transducers are
intended for use at test frequencies between 125 Hz and 8000 Hz. This unit meets the
requirements of both ANSI S3.46-1997 and IEC 61669:2001. These standards specify the
required precision that the Avant ARC does achieve.
The AVANT ARC is an electronic instrument intended for the testing of human hearing using
both tone and speech audiometry. This device meets the specifications and tolerances for
audiometers and standard reference threshold levels for audiometric transducers such as
supra-aural, circumaural, and insert earphones, bone vibrators, and loudspeakers as defined
in ANSI S-3.6 and IEC 60645.
The AVANT ARC conforms to the RoHS directive 2011/65/EU when used with the supplied
accessories.

Loading Calibration Files
Each AVANT ARC audiometer is calibrated in
compliance with the ANSI S3.6 standard. This
calibration procedure results in a series of files
that the AVANT ARC software reads to keep the
hardware in calibration. These files are supplied
on a USB Flash Drive the same serial number as
your AVANT ARC device.
The final step before using your AVANT ARC to
evaluate hearing is to load these device specific
calibration files onto the computer used to
operate the AVANT ARC device.
1. With the MedRx USB Flash Drive
connected, open the AVANT ARC
software and Click:
•Function.
•Calibrate.
•Load Calibration.
2. After a few seconds, this message
will appear.
•Click Load.
3. When the files are finished being
loaded, this message will appear:
•Click YES to complete loading
the calibration.
