Chapter 1. Information and safety 1.9 Cybersecurity
1.9 Cybersecurity
As the device and its OTOWIN software are computer-based systems that are integrated into larger information sys-
tems, certain rules and good practices must be put in place to ensure the safety of patients and users.
Électronique du Mazet does not provide or control the operating environment of its products, so it is the responsibility of
the practitioner to ensure that the following recommendations are followed.
1.9.1 Good practices for computer security
-Keep your software up to date, including the operating system (Windows or MacOs)
-Use operating system accounts to manage access.
-Use strong passwords to access accounts
-Lock down the computer when not in use
-Back up the OTOWIN database regularly (see 5.4.1)
-Verify the authenticity of any third-party software you install
-Use anti-virus software and a firewall
-Since the device and OTOWIN do not need to access the Internet, isolate the computer from the network as much as possi-
ble.
-Check echodia.com periodically to see if updates are available.
1.9.2 Technical Information
-The OTOWIN software is a Java program
-It embeds its own java execution environment (JRE+JVM) in order not to interfere with other software. (installed in the
same folder, by default : C:\Program Files\Echodia\Otowin\jre)
-The configurations of the software as well as the database are saved in the .otowin folder of the user folder (ex: C:\Us-
ers\romain\.otowin).
-The software uses the port 32145 of the local loop (localhost / 127.0.0.1) in order to check that there are not several in-
stances of the software launched at the same time.
-The software uses a proprietary USB driver to communicate with the device
ECHODIA advises you to regularly renew the password of your device. It is also advisable to activate the
lock mechanism of the computers on which you have installed the OTOWIN software after a short pe-
riod of inactivity.

Chapter 3
Introduction and test setup
Audiometry is the basic hearing test. This test allows a quick check of the entire sound transmission chain to the
brain in a discriminating manner. The measurement is obtained by emitting a frequency-calibrated sound wave, the power
of which is reduced as long as the patient hears it. The sounds are emitted by an acoustic stimulator in one of the ears,
then in the other.
Pure-tone Audiometry allows the investigation of hearing thresholds for each ear, in a frequency range from 125𝐻𝑧
à 8𝑘𝐻𝑧. While bone conduction assesses the performance of the inner ear and the auditory nerve, air conduction tests
the entire acoustic function from the outer ear to the auditory nerve. The resulting audiogram is interpreted to measure
the degree of hearing loss and the type of hearing loss. Tone audiometry also allows the determination of the discomfort
threshold, or the search for the frequency of possible tinnitus.

Measure in ambulatory mode
4.1 Patient management
The OTOWIN device allows a good organisation of the
measurements thanks to its advanced patient manage-
ment system.
From the home page, select the "Measure" mode: you
can then choose to search for an existing patient or cre-
ate a new one.
4.1.1 Creating a patient
When creating a new patient, five pieces of information
are requested: name, first name, birth date, company
and gender.
To enter this information, simply click on the required
field and the keyboard will appear on the screen.
It is possible to use a numeric keypad by clicking on the
"123" key at the bottom left.
Here the patient information is brief. You will be able to fill in more details when exporting the data to OTOWIN.
Please refer to section 3.2
By entering the patient's date of birth and gender, the normal hearing thresholds can be plotted.
To create a new patient, it is imperative to indicate a Name and a First Name. Please note that it is recom-
mended to enter the date of birth in order to allow the OTOWIN software to organize the patients in the
database.
The date entry format must be in the form DD/MM/YYYY. The OTOWIN automatically formats the en-
try.

4.1.2 Patient follow-up
Once a patient has been created, his or her record is saved
on the memory card. It is then possible to find it by click-
ing on the "Search" button.
A table is displayed with the list of patients sorted in
reverse order of their registrations (the last patient added
appears at the top of the list).
The list of patients is displayed with their name, first
name and company. It is possible to search by clicking
on the magnifying glass at the bottom of the screen.
To select a patient, click on the corresponding row. A
new page will appear with the patient's details.
Now there is the choice of taking a new measure or
viewing previously saved measurements.
The "Consultation" button gives access to a table of
measurements allowing you to go back to the diagnoses
previously made for this patient.
In order to find the measurements of the selected patient,
their main information is displayed (type, date, time and
ear).
The "Diagnosis" button is used to start a new audiom-
etry.
4.2 Audiometry
Refer to the paragraph 4.1for instructions on how to create a patient and start a new measurement.
When you select "Diagnosis" you can choose from four
different modes:
• Automatic patient mode,
• Automatic doctor mode,
• Manual doctor mode,
• Weber mode.
The last button allows you to see which stimulator is
active and to switch between the two audio outputs.
Thus, it is possible to connect the headphones and the
bone vibrator (each to one of the audio outputs) and
switch between the two by clicking this button.
If the patient does not yet have an associated measurement, only the "Diagnosis" button is visible.
For the configuration of the frequencies used, start power of the automatic proto-
cols, please refer to paragraph 2.2.1.
