AUDECOM - General Information
The AUDECOM offers a comparative auditory system adjustment in an objective/oriented
manner in real time and thereby makes your work more effective and more seamless:
An intelligent, software-supported customer dialogue will guide you through the ad-
justment and toward a quicker decision on the performance class desired by the
customer.
The customer will directly hear the different between up to three hearing aid types. To
do this, it is necessary to switch between the auditory systems by pushing a button
He can thereby decide more clearly what is useful to him and make some clear spe-
cifications to the acoustician.
The customer - AND NOT THE ACOUSTICIAN - changes between the models and
can thereby recognise more quickly which auditory system he really prefers and is
useful to him in his daily routine.
Sound samples are supplied by surround sound and make it possible to implement,
rate and assess qualitative differences in wind noise suppression, verbal reproducti-
on, music reproduction or adjustment characteristics.
With this basis, the customer and the acoustician can usually decide in one sitting
which of the compared systems are actually worn and can best be gradually further
adapted.

Safety instructions
The purpose of the AUDECOM is intended to present the differences bet-
ween various systems to the customer live in a convenient, and most im-
portant, comfortable manner, based on sound samples with the comparative
adjustment of auditory systems.
All other purposes of the device and the accompanying controller that do not
meet this purpose are contrary to purpose and are therefore not permitted.
The following safety notices are to be noted when operating the device:
Attention! If you or the person accompanying the user move in the
room, ensure that the headphones are put down or when
the device is removed, the cable length of the headphone
should be taken into account. Disconnection the AUDE-
COM by the headphone cable or yanking on the cable/
headphones must be avoided because damages can
occur.
Attention! Under no circumstances should the AUDECOM come
into contact with ultrasound baths, running water and
chemical cleaners, e.g. diluters, alcohol etc. It could be
damaged or destroyed.
Attention! Do not remove the cable (power, headphones, USB con-
nection) from the device. The cables could be damaged
and the device moved and even pulled off the table. Hold
the device carefully with one hand. Grasp the respective
connectors with the other and carefully remove it from the
device.
Attention! Only use the AUDECOM in dry rooms and protect it -
from wetness and dampness - both when working and in
a deactivated state. You or third parties can be injured.
In addition, the device could be sustainably and heavily
damaged.
Attention! Only use the supplied power supply to operate the de-
vice. It was especially developed for the AUDECOM.

Installation and commissioning
In this chapter, you will learn how to install the AUDECOM and the software
and which test room situation you need to follow.
Select an area
Select a quiet room with as view noises as possible for the adjustment. The
room should allow the following setting:
The room should be large enough so that you or the person accom-
panying the customer can freely move in the room in order to offer
communication from different directions.
Position the device on a table which is as free as possible on all sides.
The customer should only sit in front of the device in such a way that
he can operate the keys comfortably and can see the mini-lamps next
to the auditory systems. They means that he can easily recognise bet-
ween which auditory systems he can toggle and currently hears “in his
ear”. This makes it easier to note his impressions and comments on an
assessment form. He should have sufficient room for this.
You are sitting behind the AUDECOM, i.e. on the side in which the
headphones are connected and their volumes can be adjusted.
On the table, there must be enough room for a monitor and a compu-
ter keyboard with a mouse. The recommended setting is a computer /
laptop with an additional monitor so that you have access to the Expert
view and the customer has access to the Customer view on separate
monitors.
Installation and commissioning

7
Connecting the AUDECOM
The AUDECOM system is designed in such a way that it can always be in-
stalled as an operating unit. Thus, no new installation is generally required.
1. Insert the small USB connector of the supplied power supply into the
socket provided onto the back of the device.
2. Insert the plug of the power supply unit into a regular 230V mains socket.
3. Insert the small USB connector of the supplied USB cable into the
socket provided onto the back of the device.
4. Insert the large USB cable connector into a free USB port on the
computer.
5. If this does not occur, connect the acoustic shadow (Plexiglas® head) to
the bolts on the top of the AUDECOM.
Note: Plexiglas®distorts the visual impression. Get behind the device and
place the acoustic shadow vertically onto the bolts. Please note the
direction: The “nose” of the acoustic shadow must point in your direction,
i.e. to the side to which the headphones were connected and the volume
has to be changed.
6. Equip the auditory system connection jacks each with a
silicone hose - matching the auditory systems which you
will use (HDO or RIC).
7. Activate the five loudspeakers. To do this, push the sli-
der located on each loudspeaker to the ON position. On
the silver back, an LED with the colour meaning indicated
below will be illuminated.
Tip: Hold on to the loudspeaker with one hand
and press the key with the other hand. You
can thereby prevent the loudspeaker from
getting loose from its ground attachment.

Setting and adjustment
In this chapter you will learn how you can optimally prepare and implement
the session for an auditory system comparison.
Prepare the adjustment as follows:
Prepare the adjustment as follows::
Before the customer arrives ...
1. Start theAUDECOM on the computer. If this is not installed on your com-
puter, follow the steps in the chapter Installing Software.
2. On the start screen, click on the manufacturer logo. You can use its au-
ditory systems for the next comparative adjustment.
3. Switch on the AUDECOM.
To do this, turn the switch on the left (headphone side) to the left.
The operating LED’s are illuminated in blue to display the status.
The computer will attempt to establish a connection to the AUDE-
COM. If it was possible to establish a connection, the connection
LED is illuminated in green.
The loudspeakers automatically increase the volume to the maxi-
mum to always offer a consistent initial output volume. This process
takes approximately 10 seconds so that a volume change is completely
normal during this time.
Tip: In order to save power, you can switch off the loudspeakers if you will
not use them for the foreseeable future. Do not forget to turn off the lou-
dspeaker when you conclude a session with the AUDECOM. In order to
test whether the loudspeakers are connected, please note the following

After the customer arrives... ...
1. Program the auditory systems in the traditional manner according to the
audiometric measurement results. Here you must follow the setting in-
structions included in the program for the best possible effects! Here use
three auditory systems of only one manufacturer and ensure that you
choose from different quality and price segments: Basic - Middle Class -
High-End.
Alternative: 3standard systemswithanoptimisedsettingaccordingtoauditory
system manufacturer information. Fine adjustment later with the auditory
system according to the AUDECOM selection.
2. Connect the auditory systems to the hoses.
Please use the special position for the auditory
systems for RIC systems.
3. On the main screen, always select the respec-
tive auditory systems which you have con-
nected to the respective connection jacks. Here note the order:
Tip: If the auditory system does not correspond to the correct auditory system
which you connected to the AUDECOM device in terms of colours, you
can change the display colour if the image file for it is provided. Right-click
on the image. An image pull-down in which you can click on the correct
4. Print the assessment form out. To do this, click .
5. Give the following to the customer:
Pen
Assessment form with an appropriate notice: Please always fill
out the form during comparison. Please also note sensitivities,
impressions, positive/negative characteristics of the individual
auditory systems compared to the others. Then you have a good
basis for your decision.
Headphones which are connected to the AUDECOM and ask
him to position them on the correct side.
6. Change the volume for the customer as required. Please for contact
the customer for this purpose: Listen clearly and is the volume pleasant
for you? To do this, turn the control knob until the volume is considered
agreeable.
louder: clockwise
quieter: counter-clockwise
7. Repeat this for the person accompanying the customer and for yourself

Briefing customer ...
Before the adjustment, it is important to mention that the hearing impression
for the adjustment would be exactly the same as the customer will have in
the future. The auditory training and the process of becoming accustomed
which follow an adjustments will usually only improve verbal comprehension.
The auditory systems are only roughly adjusted to his needs - fine-tuning
occurs based on device selection.
Rather, the idea behind the process of auditory device comparison with
AUDECOM is to give the customer an impression of the audio quality and the
performancedifferencesof theauditorysystems.Thecomparisonhas the goal
of showing the (added) benefit in the comfort range which the (higher quality)
auditory system will offer in the future. Thus, the customer can assess based
on the differences which auditory system he would like to use and which
system he is willing to purchase:
How does wind noise suppression work?
What benefits does a special adjustment characteristic have?
How is the music and vocal replay in the different performance
classes?
The timeframe and the listener experience/adaptation are required so
that differences in one’s daily routine can be recognised.
“It is important that you can make an assessment based on your
own experience and make a decision on the auditory system most
suitable for you“
Inform the customer that he will be changing between the auditor systems
himself to be able to select in each case which auditory system he would like
to directly compare with which other auditory system and when. It is therefore
a good idea to only toggle after approximately 15 to 20 seconds because the
auditory systems must adjust to the sound situation in order to develop the
full scope of their performance.
Toggling between the auditory systems (for customers explanation):
Select the desired auditory systems with the three keys at the bottom right:
Key 1 for auditory system 1
Key 2 for auditory system 2
Key 3 for auditory system 3
You can recognise which auditory system is
currently selected by the mini-lamps next to
the auditory systems.
Setting and adjustment

Performing an adjustment
1. Click on the existing images of the sound samples in the lower screen
section on the sound samples which the program provides for which you
would like to demonstrate the differences between the auditory system
types. The sample sounds are each played and the corresponding
image next to the note of which the customer should be aware is shown
enlarged.
2. Let the customer operate theAUDECOM himself below. You allow him to
decide between the performance classes himself.
Note: This will allow you to rebut any reservations. You can influence a deci-
sion for or against a certain auditory system or even steer the decision.
On the contrary: By selecting the auditory system himself, the customer
will be more likely to identify with his auditory system and then become
familiar with it.
Important: Follow the following instructions when sound samples can now
be heard:
Do NOT speak when voice-based sound samples are now run-
ning.
You or the person accompanying the customer should speak
when pure noise/sound samples run out.
If you are using two monitors - for example a laptop with a connected
motor - switch to two-monitor-mode . That means that you
show the customer the Customer view and
the expert view for you .
In addition, you will also receive additional information on the auditory
systems you selected in your specialised language. You can also click
on the following buttons:
: View special information from the manufacturer
: Start the videos for the respective auditory system
You can do the following in the Customer View in the centre screen
