Virtual clinic

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.

  • Six simulators: audiometry, acoustic immittance, OAE, ABR, hearing aid and cochlear implant share the same clinic.
  • 96 clinical cases: with three practice modes, from guided learning to working on your own.
  • Assessment: your findings, interpretation and recommendation are compared with the expected answers.

Case History Forms

Fillable case history forms for adults, children aged 0-6 and school-age children. Downloaded as PDF; can be completed on a computer or printed.

  • Three forms: adult, age 0-6 (completed with the family) and school age (6-17).
  • Must-ask questions marked: BAA, BSA and NICE referral criteria; JCIH (2019) risk indicators for children.
  • Coverage: reason for attendance, onset and course of hearing loss, ear symptoms, medical history, noise and family history, device use.
Open the forms On the Academy page
New · Listening

Hearing Loss Simulator

Listen to speech, music, the Ling sounds, everyday sounds or your own recording through the hearing loss you choose.

  • 17 preset audiograms: or right and left ear thresholds you mark yourself; conductive and sensorineural components.
  • Suprathreshold effects: loudness recruitment and reduced frequency selectivity; tinnitus, reverberation, distance and noise.
  • Comparison: listening through a linear or compression hearing aid, a live spectrum, SII and WAV download.

New · Cochlear implant

Vocoder Simulator

Pass speech and music samples through a channel vocoder that works much like cochlear implant processing, and listen.

  • Channels and insertion: number of channels, sine or PSHC carrier, insertion depth on the Greenwood map and current spread.
  • Advanced settings: electric-acoustic stimulation, n-of-m channel selection, disabled channels and background noise.
  • Exercises and report: a channel map, spectrograms, A/B and blind listening exercises and a full parameter report.

New · 3D

Cochlea Simulator

Explore the cochlea in 3D from any angle, from the travelling wave to cochlear implant stimulation.

  • Mechanics: the travelling wave, tonotopy and level-dependent compression; inner and outer hair cells.
  • Types of hearing loss: presbycusis, noise-induced loss and dead regions.
  • Devices: hearing aids, cochlear implants and hybrid (EAS) stimulation.

Where should you start?

A suggested order, from the basics upwards. Click a tool and it opens in the panel above.

01
Learning & practice

Fundamentals

Explore how the ear and the cochlea work, and the key terms, interactively.

02
Audiogram

Audiogram reading

Practise pure-tone audiometry, audiogram interpretation, masking and PTA.

03
Diagnostic tests

Tests and reasoning

Start from the case history; interpret immittance, OAE and ABR findings together.

04
Hearing aids

Devices and verification

Compare device types and examine the processing inside the device and real-ear verification.

05
Learning & practice

Awareness

Listen to how sound is heard with a hearing loss and with a cochlear implant.

What are these tools for?

Interactive tools built to support practice and curiosity in the hearing sciences, and to put knowledge to work.

Note: These tools are for education; they are not diagnostic, therapeutic or clinical decision tools.

On the Academy page you can set assignments with the simulators, print lab worksheets and practical exam checklists, and gather the class codes your students send into one table. Academy: Simulators in class

For anyone interested in the subject, from the curious newcomer to the specialist. Most can be tried without any prior knowledge.

No. The tools are for learning and practice only; they do not replace a clinical assessment, a diagnosis or professional judgement.

Yes. Write to info@isitmeatolyesi.com with the tool you would like to see; the collection grows with feedback.
