1. GENERAL INFORMATION
1.1 INTRODUCTION
The MIDIMATE 622 is the second member of the new generation of
audiometers from GN Otometrics, which started with the Midimate 602. This
dual-channel clinical/diagnostic audiometer features a unique multi- lingual
menu-driven display and five user-programmable test setups for optimal
operating efficiency during daily routine examinations. New features
incorporated into the MIDIMATE 622 include, amongst others, data inter-
face, 1 dB attenuator resolution, ipsilateral masking, and simultaneous
presentation of stimulus and masking binaurally.
Introduction to the
MIDIMATE 622
State-of-the-art technology has enabled GN Otometrics to produce a
compact lightweight instrument not only capable of performing the standard
battery of tests but also featuring many other advanced and innovative
facilities.
All these features have been incorporated into a strikingly simple user-
friendly and ergonomic design, which makes operation fast, easy and
efficient. Silent electronic rotary frequency and attenuator controls have
been provided for optimal operator convenience and comfort while the
hearing level control and the interrupter bar have been arranged to
accommodate both left- and right-handed users.
Human Engineering
In addition, GN Otometrics has developed a completely new attenuator
which permits totally clickfree operation over the entire attenuator range.

Attenuators
Simple and logical multilingual menu-driven dialogue makes the MIDIMATE
622 easy to learn and easy to use. Working with a menu-driven display is
uncomplicated: the upper line simply prompts the operator to select one of
the options from the lower line by pressing the appropriate softkey. In this
way, you can rapidly set up tests and then alter them as required.
Furthermore, up to five test setups may be preprogrammed for instant one-
key retrieval of your most frequently used test setups. The display itself is
easily readable under any lighting conditions and from any viewing angle
thanks to state-of-the-art LCD technology.

Display
In addition to a complete patient communication and monitoring system with
talk-over and talk-back facilities, patient response may also be audible, if
desired, enabling the operator to concentrate visually on the patient.
Patient
Communication
The MIDIMATE 622 is fitted with an RS232C serial data interface as
standard, enabling data transfer to and from a computer, entry of a patient
identification number, and printout of audiograms.

MateBase
I,
GN Otometrics's own audiological software, is supplied free of
charge with the audiometer, permitting patient identification and audio-
metric measurement data to be transferred to a PC for subsequent pro-
cessing, printout and storage. To communicate data from the MIDIMATE
622 to MateBase
I
, version 2.0 or higher is required.
