Getting to Know Your AVANT ARC
The AVANT ARC (Audiometer and Real Ear Measurement Combination) represents a new era of ultra
compact diagnostic audiometry and precision in-situ verification for your office. Compact yet rugged, this
PC-Based system is USB powered and supports current ANSI and IEC audiometric and Real Ear tests.
This Installation Manual and the Training Manual are supplied with your device in pdf format on a
CD. Software to view the pdf files is included on the CD for your convenience.
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 client'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.
