Effective Date: 06-01-2015
Introduction
The AVANT A2D+ Audiometer represents a new era of ultra compact diagnostic audiometry for your
office. Compact yet rugged, this PC-Based system is USB powered and supports current ANSI and IEC
audiometric tests. This manual assumes that the system hardware, software and drivers are installed and
working properly. Please refer to the MedRx AVANT A2D+ Audiometer Installation Manual for
assistance. The Installation Manual is included in the original AVANT A2D+ Audiometer packaging in
both printed and PDF formats.
The scope of this manual is to get you “up and running” with the AVANT A2D+ Audiometer System.
Please consult the interactive Help System within the software for more detailed information of features
and functionality. To access this tool, press the F1 key at any time, or click the Help icon or text menu
with your mouse. Access these by clicking on the “Help” tab at the top of the screen, and select “Help

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. Those standards specify the required precision that the Avant A2D+ does achieve.
Measurement uncertainty is +/- 1 dB.
This device and transducers are intended for use at test frequencies between 125 Hz and 8000 Hz.
The Avant A2D+ Audiometer 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 A2D+ Audiometers are typically used to measure patient hearing loss, the degree of hearing
loss, and to create audiograms that will be used by the manufacturer of hearing aids to set the correct
gain levels for various frequencies.
