With this audiometer simulation web app, you can practise your audiometry skills on simulated patients.

• In the tab 'Create random patients', you can create patients based on a number of 'typical' audiogram configurations. These patients are generated automatically by the app in a random fashion so that so that all patients are unique properties, that basically will never be created equally twice. Thus, there you work with truly unique patients.

• In the tab 'Load patient from file', you can load patients defined either in text files or in binary (encrypted) .simpat files. Both file types need to contain the following information about your patient.

  • True inner ear thresholds for right (TTR) and left (TTL) ears.
  • Conductive components for right (CCR) and left (CCL) side.

  Here 'True inner ear thresholds' are defined as the average pure tone threshold you would get in many repeated tests if the patient had no conductive component. The TTR, TTL, CCR and CCL data need to be supplied for the following audiogram frequencies: 125, 250, 500, 750, 1k, 1.5k, 2k, 3k, 4k, 6k, and 8k Hz.
  

  The encrypted binary files can be created in the tab 'Create encrypted patient file'. The text files you can create in any text editor as long as they are structured like the following sample patient, where TTR, TTL are the right and left inner ear thresholds, and CCR and CCL are the conductive components (in the order of rising frequency, i.e. from 125 Hz to 8 kHz): Please note! Only use integer values (i.e. no decimals!) delimited by blank spaces. The ID row is optional and can be left out.

  • E - Signal channel 'AC (R-L)' button
  • R - Signal channel 'BC (R-L)' button
  • T - Signal channel 'Insert phone' button
  • S - Higher frequency
  • K - Lower frequency
  • P - Masking channel: level up
  • L - Masking channel: level down
  • Y - Masking channel 'R' button
  • U - Masking channel 'L' button
  • I - Masking channel 'Insert phone' button
  • O - Masking channel 'Rev' button
• About the 'Show audiogram' button:

  When you create a patient using the “Create random patients” tab, you can click “Show audiogram” to view the patient’s true audiogram (rounded to the nearest 5 dB step). When loading patients from a file, this feature is disabled to prevent you from peeking at the audiogram.

Here you can create a random patient. Just select the type of audiograms you want to practice on below, and then press the 'Create new patient' button. The simulated patient will be automatically loaded into the audiometer and respond to your signal presentations very similar to a real patient.

Here you can load patients defined in text files or binary files. You can produce your own text files using any text editor and save as in txt format. See the instructions tab for correct text-file format specification. Only binary files created in the tab 'Create encrypted patient file' can be used here. Such files may have been sent to you by your teacher.

Select the patient file to upload and click the button 'Load patient from file'. Your simulated patient will be loaded into the audiometer and respond to your signal presentations very similar to a real patient.

Here you can create an encrypted file with a simulated patient. Once created, the file can be uploaded in the tab 'Load patient from file'. The file is created in a format called .simpat and is not human readable. It can therefore be distributed to others without them knowing the thresholds of the simulated patient, suitable to use for controlled pure-tone audiometry practising tasks. Fill in the form for right and left side true inner ear thresholds (TTR and TTL) and conductive components (CCR and CCL) of your simulated patient. You can use any of the example audiograms and modify them freely, or create your own custom audiogram. When your're done, click the button 'Download patient file' and save the downloaded patient file on your device.
