Presentation of the device
AUDIOSMART is designed for screening, documentation, monitoring and diagnosis of hearing functions. It is intended
for ENT doctors, audiologists, pediatricians and other health professionals practicing in private or in a hospital environ-
ment. The audiometry is a behavioral examination allowing to quickly assess the hearing acuteness. Via an acoustic
stimulator, sounds, words or sentences with various sound intensities are presented to the subject. The subject reports his
or her perception to the operator who can, according to the test used, determine an absolute threshold of perception or an
intelligibility threshold.
1.2.1
Intended Use
The audiometric diagnostic test is a behavioural test for the rapid assessment of hearing ability. The subject is exposed
to sounds, words or phrases at different intensities using an acoustic stimulator. He/she transmits his/her perception to the
operator who, depending on the test used, can detect a reduction in hearing acuity, determine an absolute threshold of
perception or an intelligibility threshold. Two modes of transduction can be used, through the normal auditory pathways
using an acoustic transducer (Air conduction), or using a vibrator placed on a bony part such as the mastoid or the forehead
(Bone conduction).
AUDIOSMART is designed to perform the following otologic diagnostics :
Audiometry:
-Air conduction (AC)
-Bone conduction (BC)
-Speech

Patient data confidentiality
The device collects data. It is the practitioner's responsibility to apply and comply with the European Parliament's
General Data Protection Regulation 2016/679. When returning the device to the after-sales service, the user must delete
the patient data from it so that it is not disclosed. The practitioner has the possibility to make a backup copy of the data
by saving them in the ECHOSOFT software (see section Erreur ! Source du renvoi introuvable.)before deleting the
patients from the device (see section Erreur ! Source du renvoi introuvable.).
The AUDIOSMART device is intended to be used by authorized healthcare professionals only. To ensure the confiden-
tiality of patient data and to prevent disclosure to unauthorized third parties, a password can be set at the first start of the
device. Please refer to section Erreur ! Source du renvoi introuvable. for more information.
1.9
Cybersecurity
As the device and its ECHOSOFT software are computer-based systems that are integrated into larger information
systems, 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 ECHOSOFT 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 ECHOSOFT do not need to access the Internet, isolate the computer from the network as much as
possible.
-Check echodia.com periodically to see if updates are available.
1.9.2
Technical Information
-The ECHOSOFT 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\Echosoft\jre)
-The configurations of the software as well as the database are saved in the .echosoft folder of the user folder (ex: C:\Us-
ers\romain\.echosoft).
-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 ECHOSOFT software after a short
period of inactivity.

Introduction and test setup
Audiometry is the basic review of hearing. This test allows a quick check of hearing, from the transmission chain to
the brain. The measure is obtained through the emission of a calibrated frequency sound wave, of which we will lower
the level until the patient can't hear it anymore. The sounds are emitted by a supra-aural headphone, in one ear then in the
other.
Pure-tone Audiometry allows hearing thresholds screening for each ear in a frequency range from 125Hz to 8 kHz with
regular headset and up to 16KHz with high frequency headset. Bone conduction evaluates performance of the inner ear
and the auditory nerve, air conduction tests all of the acoustic function from the external ear to the auditory nerve.
The interpretation of the resulting audiogram allows to know the degree of hearing loss and the kind of deafness.
Pure tone audiometry also allows to find a discomfort threshold, or also the research for any tinnitus frequency.
Speech audiometry is a further investigation of the pure-tone audiometry. It does not determines a threshold of
perception, but a threshold of intelligibility of language, or discernment of phonemes. The test consist of making the
patient repeat a series of words he hears. By varying the power of diction of the words, a curve relating the percentage of
discrimination in relation to the power is obtained. Well known by hearing aid specialist to fine tune the settings of hearing
aids, it is also used to diagnosis retrocochlear pathologies like neuropathy or acoustic neuromas
