VIRTUAL CLINIC · SIX SIMULATORS · PRACTICE ENVIRONMENT

Simulation Center

Practise audiological assessment methods in a virtual clinic, with a virtual patient. You meet your patient in the waiting room, take them into the test room and carry out the measurement yourself. The audiometry, acoustic immittance, OAE, ABR, hearing aid and cochlear implant simulators share the same clinic; when you finish, your findings, interpretation and recommendation are compared with the expected answers.

How does it work?

The workflow is the same in all six simulators: open the center, meet the patient, carry out the measurement, compare the result.

  1. 1

    Open the center

    Start the Simulation Center opens the simulator menu. Choose the simulator you want to work with, or use Explore the center to start from the waiting room without choosing a simulator; you then choose the test yourself by clicking the device in its room. The menu is the same whichever page you open it from.

  2. 2

    Meet the patient

    The patient waits for you in the waiting room; the on-screen directions show which door to go to. You can click a door to go through it, or use the WASD keys to walk around the clinic.

  3. 3

    Choose the case, carry out the measurement

    Choose the case, the practice mode and the patient's cooperation. Read the ENT request, prepare the patient and operate the equipment yourself. The patient reacts too: they hesitate at levels near threshold, and swallow or cry during recording.

  4. 4

    Compare and report

    When you finish, your findings, interpretation and recommendation are compared with the expected answers; you see, step by step, what you missed and where. You can download your report and send your result to your instructor with a class code.

Virtual clinic

All six simulators run in the same building. You can walk around the clinic, from the waiting room to the test rooms and from the corridor to the rooms in preparation. Rooms that are not ready yet have locked doors; they will open as their simulations are added.

Practice modes

You can work through the same case with three levels of support. The modes mean the same thing in all six simulators.

Learning

You follow the clinical sequence step by step. Each step explains what to do and why; the next step unlocks once the previous one is complete. Start here when you practise a method for the first time.

Guided

You carry out the steps in any order you like. Norms, criteria and warnings appear as hints when they become relevant; if you make a wrong step, you see why.

Field

You work as you would in a real session; you are warned only about obvious errors. Suitable for testing yourself and for assessment with a class code.

You also choose the patient's cooperation (reliable or variable). Blind case hides the case name and history; you base your interpretation on your findings alone.

Across the simulators

You can work with each simulator on its own; when you assess the same patient with more than one test, the findings stay together.

Refer the patient to another test

When you finish a test, use Refer the patient to send the same patient to another test; for example, from audiometry to acoustic immittance. The patient arrives as the same person, with the earlier findings in their file.

Shared report and a single code

The tests you carry out on the same patient travel together in a single class code. You can download the audiometry and immittance results as a one-page combined report with the audiogram and tympanogram side by side.

Class code for instructors

The student gets a short code on the assessment screen and sends it to their instructor. When the instructor pastes the code into the decoder in the simulator, they see the measurements, answers, score and report. The code is generated only in the browser; no data is sent to a server.

Score, stars and achievements

Your score looks not only at your interpretation but also at how you carried out the measurement, and is converted into 1-3 stars. Experience points and achievements are stored only in your own browser.

Before you start

Four short notes to help you use the simulators without problems.

Computer or tablet

The simulators are designed for computers and for tablets held in landscape orientation. On a phone screen, the console, the 3D clinic and the graphs do not fit together.

Headphones preferred

Stimuli are presented to one ear at a time; use headphones to keep right and left separate. The headphones are not calibrated; the sounds are correct only in relative terms.

An up-to-date browser

The 3D clinic needs an up-to-date version of Chrome, Edge, Safari or Firefox. The scene may take a few seconds to load the first time you open it.

For educational use

The simulators are not clinical diagnostic tools; they do not replace a calibrated device or a hearing test. The reports they produce are not medical documents.

Frequently asked questions

No. All the simulators are free and need no registration. Your progress is stored only in your own browser; no data is sent to a server. If you clear your browser data, your progress is deleted too.

If you want to follow the basic assessment sequence, start with audiometry, then move on to acoustic immittance for middle ear assessment. OAE and ABR are suitable when you are working on newborn hearing screening and objective tests.

Whichever you choose, when you practise a method for the first time we recommend starting in Learning mode.

You start from the waiting room without choosing a simulator. You can walk around the rooms to get to know the layout of the clinic, and choose the test you want to work on by clicking the device in its room: the booth opens audiometry, the immittance meter opens immittance, the OAE desk opens OAE and the ABR couch opens ABR.

The simulators are designed for computers and tablets. On a phone screen, the console, the 3D clinic and the graphs do not fit together, so we recommend using a computer or a tablet held in landscape orientation.

In the Simulation Center menu, the Update notes button lists the changes in each simulator, version by version. When a new version is released, the notes are shown once, the first time you open the menu.

Please email info@isitmeatolyesi.com and tell us which simulator, which case and which step you were at; this helps us find the problem faster.

If you are ready, let's go to the waiting room

We develop the simulators with your feedback. If you find an error, or there is a case you would like us to add, email info@isitmeatolyesi.com and let us know.
