Hearing Test

The app offers two basic hearing tests: pure-tone audiometry and the digits-in-noise test (digit triplet test) for assessing speech intelligibility.

Pure-tone audiometry determines the degree of hearing loss as a function of sound frequency. The test consists of determining the quietest sound you are able to hear, thereby establishing your hearing threshold. The digits-in-noise test evaluates speech intelligibility and consists of recognizing digits presented in background noise.

Features of the Hearing Test app:
* pure-tone audiometry (using predefined calibration coefficients for manufacturer-supplied wired headphones or Bluetooth headphones),
* digits-in-noise test for measuring speech intelligibility,
* a noise meter for measuring background noise during the test,
* device calibration (when no predefined calibration is available or when using headphones other than the manufacturer-supplied ones).

Additional features:
* high-frequency audiometry,
* classification of hearing loss,
* comparison with age-related norms,
* printing of test results,
* adding notes,
* calibration adjustment (calibration coefficients can be adjusted based on your results obtained using a clinical audiometer),
* verification of calibration coefficients.

Pro version features:
* local database (offline access to test results without connecting to the server),
* synchronization (your test results can be stored in the cloud; the data are easy to recover, can be transferred between devices, and accessed on different devices),
* manual stimulus control in pure-tone audiometry (you can turn the stimulus on and off manually during the test).
