FEATURES

Perform a pure-tone audiometry on your mobile device

Main

Pure tone audiometry using bundled headphones and predefined calibration coefficients from the database (possible for systematically increasing number of devices).
Calibration of the device (in the case of lack of predefined coefficients or for headphones other than bundled).

Additional

Browsing, annotating, printing and sharing the test results.
Customizable test frequencies (125 Hz - 18 kHz).
Interpretation of the results according to the age norms.
Selection of the calibration coefficients that were used during previous tests.

Advanced

Adjustment of the calibration (calibration coefficients may be adjusted on the basis of your audiogram that was produced using an audiometer).
Verification of the calibration coefficients.
Suppressing of the masking noise for the purpose of free field audiometry.

Pro features

Local database (offline access to tests results, without connecting to the server)
Synchronization (your tests results can be stored on a remote account, created for a given email address; data are easy to recover, transfer to/from any other mobile and can be automatically synchronized on different devices)

Permissions

android.permission .INTERNET

The permission is required to download a predefined calibration coefficient from the remote database and store the test results. This is a required permission.

android.permission .RECORD_AUDIO

The permission is required to monitor the background noise during the test. The application analyses the surrounding sound and calculates its level. No other information that the sound level is processed. This is an optional permission.

android.permission .GET_ACCOUNTS .GET_CREDENTIALS

This permissions are required to transfer the data between devices. They are an optional permissions. They concern only Pro version.

Data processing

All data collected by the app are processed solely for the purpose of service provision, application development and scientific research. The data have never been and will not be forwarded to third parties. Data processing for the purpose of application development and scientific research have been and will be anonymous. At any time, upon user request, the user data can be accessed, modified or permanently deleted.

Types of data processed

Provided by the user

These data are provided by the user and are directly related to the app features. These include data such as:
- test results,
- calibration coefficients,
- optional: annotations concerning tests or subjects,
- optional: age provided for comparison with age norms.

Collected by the app

These data are implicitly collected by the app. These include data such as:
- time and duration of the test,
- device manufacturer, device model and identification number,
- IP address,
- optional: noise level during the test.

From the Google account

The only data retrieved from Google account is an email. The email is used to synchronize data between different devices of the same user and to identify data in communication with the support center. Its processing is optional and only concerns the Pro version.

FAQ

How to migrate data to new phone?

1. Install Hearing Test Pro on an old phone.
2. Import the data from the basic version (Settings -> Import previous tests).
3. Synchronize the data with the account (Settings -> Background synchronization).
4. Install Hearing Test Pro on a new phone and synchronize with the same account.

What headphones are recommended?

The application uses calibration coefficients determined for bundled headphones, which are distributed by the manufacturer together with the device. Calibration is based on calibration measurements carried out by other users thus the availability of the coefficients depends of popularity of the device model.

Extended support for Bluetooth headphones has been introduced in application version 2.4. For best results with Bluetooth headphones, we recommend the Sennheiser HD 450BT headphones.

How to calibrate the device?

Two methods are available.

1. Calibration based on the hearing threshold of the normal-hearing person.
The variability of the hearing threshold for people aged 18-35 who had no previous hearing problems is relatively small. They can determine the reference sound level in relation to their hearing threshold. Of course, if we suspect hearing loss in ourselves, we cannot perform calibration ourselves.

2. Calibration based on the clinical audiogram.
Calibration coefficients can be also adjusted so that the app results match the clinical audiogram. After completing the demo test, long click on the results, select "Adjust calibration" and enter the clinical audiogram.

How do I reuse calibration factors that have been used in a previous test?

In the app settings, select Threshold test -> Selection of calibration coefficients. Before the test, after choosing the headphones (bundled, Bluethoot or other), a list of calibration coefficients used in previous tests will be displayed.

The selected coefficients are saved as recent for the selected headphones and the option for selecting coefficients can then be deactivated.

How can I delete my account and all associated data?

To delete your account and all associated data, please send an email to biuro@e-audiologia.pl with the subject line 'Account Deletion'. You will receive instructions on the actions required to delete your data.
